Why old screens make a ʰᶦᵍʰ ᵖᶦᵗᶜʰᵉᵈ noise
HTML-код
- Опубликовано: 30 сен 2024
- Last week I made a video surrounded by old-school CRT monitors and televisions - cathode ray tubes. And I completely forgot to remove the high pitched whine they produce. Here's why: why they make that noise, and why I didn't notice it.

Last time I was here I had a professional camera operator. This time, I have... well, me. At least I checked the audio though. (Thanks again to everyone at the Cambridge Centre for Computing History!)
hey was that a Morse code or something in the end?
not just you getting old Tom, I didn't notice a thing and thought it was a greenscreen...
Well, I can still hear it. Wait the video stopped? But I can still hear it...
Jeremy is it stuck in your head? like you hear it even if the video isn't on?
Starts at 3:58. It's bloody headache inducing.
This video went from “oh cool science” to “oh mortality” very quickly
Indeed :(
So from "oh cool science" to "oh bummer science"? 😂

"...at least you can still hear it."
Me: "Can I though?"
(1 second later)
Me: AAAAAAAAAA
never gonna give you up, never gonna let you down
Arrghh! The pain!
This is funny, video still great!
There is secret morse code ;)
What do you mean? There was just the end card
>"Sorry you were slightly inconvenieced by my video, I was too busy confronting my impending mortality"
This video got dark.
It really did.
when did it say that
@@huntleysheep4787 more like paraphrasing the entire video
@@huntleysheep4787 Near the end, that "I'm getting older" is the most obvious clue
@@billkoul9780 Well, at the end, it is customary to fade to black...
I heard the high-pitched beeping at the end. I recognized it as morse code. I downloaded the audio for the video, put it into audacity, and transcribed it. I wasted 30 minutes of my life on this, just to see that I was writing down "NEVER GONNA GIVE YOU UP"
Thank you for sparing me the time bc the curiosity was about to drive me mad
Lmao
GODDAMNIT TOM

Thank you for doing it so I don't have to
As you get older you start hearing a low pitched grunt every time you get up from a chair. Its odd
W92Baj - Minecraft and games Hi Baj!
i hoping someone can explain this more, becuase that sounds depressing.
@concurrent Flame, I think it's a joke about things taking more effort as you get older, like getting up from a chair and making a grunt from the effort.
I'm already doing that. I'm 26.
Baj!
WHAT THE MORSE CODE AT THE END SAID: "NEVER GONNA GIVE YOU UP". I like the sense of humor
Morris code?
Thank you this is what I was looking for
Morse* My bad.
From 3:59 onwards
That was a very painful version of morse code.
Tom: Well, at least you can still hear it

I noticed it, but only slightly. When I turned off the 20 year old plasma TV I used as a monitor and listened on the laptop speakers, it was very obvious. That plasma also puts out quite a buzz, and it was drowning out the audio.
It's not the same noise that CRTs make (it is 1080p after all), and it changes based on how bright the picture is. My newer 4K LED backlit LCD also makes a high pitched buzz based on how bright the picture is. It's so annoying that I turned the brightness down on the TV just so I don't have to listen.
@@questioner1596 That's just....weird. You must be superhuman. Lcd's don't make sounds
@@unliving_ball_of_gas, it certainly does make a sound, and I find it worse than the CRT TVs' sound because its fluctuations make it more noticable.

Yeah, that was a bit depressing... it reminded me of how much older I am getting as well!
What manga is in your pfp?
I can't believe I spent 10 minutes translating the morse code at the end just to get rick rolled. Tom, I'm disappointed in you.
You should know better than that. No one would be disappointed at that. Except us who did not hear it.
What did it say?
Wtf I didn’t hear it
we're no strangers to love
@@filiplayz1893 I have bad news for you
This used to be my "superpower" as a kid. I could always tell when the television was on without even looking at it and with seemingly no sound. Sometimes when a TV takes a long time to start and my parents would keep pressing the start button, I would tell them to just wait because the TV had already started and is just loading. Other times when someone would watch the TV on mute (to avoid disturbing sleeping people in house) i could still tell the TV was on because of this sound. I genuinely thought I had a superpower
Same! I could pick out where in the computer lab a monitor was left on too, not always perfectly, but enough to go to the right row instead of walking the whole room. I wonder if I still can.
Back in the 1970s my second ever job was as an apprentice TV Engineer. Because I was hearing that 15,625 Hz noise all day long in the workshop, I think I must have learned to mostly tune it out. Back in those days most TVs had a "Horizontal Hold" - I could adjust it by sound alone knowing that, when it was set right, it didn't appear as loud to me.
SAME! My mother used to go nuts turning the tv on and off b4 the picture could start and I was watching in amusement hearing the noise getting on and off.
@@Nimerian what a lad
this is exactly what I've been through (:
"At least you can still hear it."

Let the record show that Jorge here figured it out first.
Maybe you'll get older Tom Scott but memes will live on forever
Tom Scott rick rolled yet again
You Rick Rolled us?!
But the big question is, do you hear it Tom?
who remembers when you could tell if someone left the tv on the moment you walked into the house?
Babalooza I miss those times 😢
i dont
Everyone
A freakin superpower
i have strong memories of back in school when you walked down the hall past a bunch of classrooms, if the door was open you heard the sound for a second.
Bravo, Tom, for showing some vulnerability, something that seems to be more and more lacking these days.
The bulk of the video explains why, as a kid, I knew when one of my siblings had snuck downstairs to watch tv in the middle of the night.
I guess they are all traumatized now and this may be a too private question? But if not, why not ditch age restrictions at all if midnight program does not seem to have harmed them?
@@offichannelnurnberg5894 They were watching cartoon videotapes.
That turned depressing real quick.
even more depressing fact: the mean thing is, even tho you cant hear high frequences, they can still damage your hearing. thats why these animal ultrasonic devices are so increadibly dangerous and dumb.
I know right I some reason feel sad for tom
I sat through and painstakingly wrote out that morse code, and you rickrolled me Tom, I don't know what I expected
Protect your hearing, then blasts high pitched hell at the end.
What high pitched hell?

Oh. :(
Har Simaja if you are on a phone, it doesn't play those frequencies, i had to turn on my headphones to hear it
@@tanuki9691 My s10 plays it just fine tho
@@TheScaith depends on the quality of the speakers probably
@@46rt76 Yea, although s10 speakers are neither really good nor really bad, I just thought that the frequency range would be something that stays rather consistent in smartphone speakers. It's usually more about how low and how loud the small thing can get and the frequency of that morsecode is about that of the higher frequencies a high hat produces, which you really don't want to be missing from your music.

I checked with a spectrogram app and it's actually there. So sad :(
Yep - I can't hear even a suspicion of Morse code.
I can hear it, but only in my left ear
Just found out my right ear is totally bad at both high and low frequencies
I can hear it if I switch my volume from low to high, because then I can tell which new frequencies have been added to the mix. Otherwise it just blends in.
The morse code is ringing in my ear now. I'm continuously getting RickRolled.
hahaha i just noticed
Do you know what it says
NEVERGONNAGIVEYOUUP
Now I wished that I had learnt Morse code. Cos I could hear it but didn't know what it was trying to say.
@@flyinggreenbee never too late to learn it
I though being able to hear when CRT screens were on was my childhood superpower. My parents couldn't hear that pitch and when I told my friends they didn't seem to know what I was talking about, so I thought I was one of few people that could do it. I haven't been any more disappointed with an informative RUclips video in my life.

Anybody know how Tom made the words 'high pitched' appear as superscript in the video title?
@@paulf1071 superscript text generator
Well, this is among the more elaborate ways I've been rickrolled.
I'm impressed
Me, being a pilot in my twenties hearing the end card: "Wait a minute, that sounds like Morse! 'N..e..v..e..r..g..o..n-' oh for feck's sake"
You have to admit, it's one of the most clever ways to rickroll all of RUclips...
Wait, what morse co... oh... *sigh*(
The second I heard beeping, I knew that was the morse code but I had no idea what it meant lmfao
He cant keep getting away with this!😩
LMAO
There's a real fun game you can play when you've got sensitive hearing but you also deal with loud noises often. I call it "Am I actually hearing something or have I finally developed tinnitus". Loads of fun.
I feel like Tom was hiding sad feels when he started talking about age and hearing... :(
I think so too, it's sad to see :(
at 4:00 there's some type of high pitched morse code sounds playing. Tom, you're the definition of attention to detail, even if you can't hear your own jokes anymore ;)
SummerWizz1 if only someone here was young enough and knew Morse code
Pamgin that's a very good point!
I caught it... and now I want to know what it was
Pamgin I am young enough to hear it (28 but still...) and am a Licensed Amateur radio operator, but I still haven't mastered CW/Morse-code.
I'll try to get the pitch down and ask a very skilled friend on Wednesday.
SummerWizz1 it probably says "things you might not know"
That noise is a *wonderful* noise when you're a kid in school, and you can hear that you're going to be watching a video instead of regular, boring class.
Me Auntie Nora
I guess it also indicates that your school doesn't have enough money to replace 15 year old televisions though.
I heard that noise a lot.
Haha, indeed... it could also be true that I haven't been in school in 15 years as well.
We had a TV in school which was so loud that it would drown out the audio... Our teachers didn't understand why we were complaining.
No idea about in Europe, but in the U.S. schools are dreadfully underfunded for the most part.
Still to this day, many grade-schools use the old TVs and see-through plastic/magnifier projectors.
It's less wonderful when the teacher leaves the TV on for the entire period after watching a 10min video and you sit right next to it...
When you’re 17 and didn’t hear anything at the end 🗿
this got strangely emotional
The feels.
>ywn regain your hearing
Bit cringeworthy how he Nearly started crying
When the video ends but you still hear ringing...

Its not your ear ringing, its a morse code :D it translates to "never give you up"
Considering what Tom said, we're lucky we could still hear it (*^o^*)
@@kurigohan7800 I think they meant after the entire video ended, which would mean they have tinnitus like me
wait which type of ringing
i have a white noise type ringing
like when you turn on a tv from the 2000s
I could still hear it after the video but i could not before. Did it cause tinnitus?
I literally just turned 28 yesterday and you hit me with this
That took a sudden sad and introspective turn that I don't normally expect from your videos, but it was sincere and touching. Thanks, Tom.
3:59 I just got Rick Rolled by high pitched morse code.
what?
ah so that's what it was, thanks tom

Yes, it's a rick roll.
It was a high pitched noise

"Protect your hearing" as i listen to high quality bassboosted memes every day
Bass is a different frequency and near harmless to hearing. If it's around your natural frequency it can disintegrate organs
@@dcarbs2979 "Near harmless"
"Can *disintegrate organs* "
I'm getting seriously mixed messages here
@@thejojomonado3647 Audible bass is near harmless. The frequency you need to disintegrate an object is the natural frequency. For humans that's 7Hz (below the audible range of 20Hz). And you'll probably need a bigger amplitude than domestic hifis can produce to achieve it. Club and festival-scale PA's should be able to do it!
Ears have smaller components, more susceptible to damage from higher frequencies.
If that's are frequncey, I wonder why I have not heard if sound weapons.
@@dcarbs2979 while resonating at our natural frequency can be discomforting, it will not desintegrate organs. The natural frequency of a human body ranges from 3Hz to 7Hz, with newer studies saying up to 10Hz. However different body parts have different natural frequencies.
Is that morse code at the end card?
Yes, and according to some other comments, it says
"Never gonna give you up"
Anyone know morse code?
is that actually what it says or are you just posting a stale 2005 dead meme

It does, in fact, say "never gonna give you up".

My tinnitus developed at a very young age and it has always sounded sort of like the CRT whine, but also warbling in directionality. I think I've always had it, but it has become louder as I've gotten older.

I went back and listened to the previous video. I couldn't hear the high pitched noise either.
Maybe we need to view the inability to hear such noises as an asset. At level 7, we get +4 resistance to sonic damage.
Unfortunately, that's not how it works. You can't hear it - and it still damages your hearing. Sort of like how you can't see UV light, and it'll still boil your retinas. This stuff's super unfair.
I can hear it but just barely. For contrast I had no problem hearing the easter egg at the end of this video. I think the humming is just low in volume and at a frequency made by a variety of electronic devices (or ear congestion).
Jeremy Baxendell An immunity to Unrelenting Force... FUS RO DAH!
You could also have speakers/headphones that can't play those noises, as well. And it does not make you more resistant to sonic damage, it means you already have it.
what's the last video with the high pitch noise?
The gap in my front 2 teeth is the perfect size to allow me to make the mosquito noise. I can adjust the pitch up and down and have always been able to bring the pitch beyond my own range of hearing. (I had people tell me they could still hear it after I couldn't anymore.)
This video made me think about my ability to do this over the course of my life. Good stuff.
Wow, I have the same talent too, except for the part about not hearing high frequencies, I really didn't think I would meet anyone who could do it.
Thanks, I unlocked a new skill today
I use my lips to adjust the hole and the frequency. But Idk if I can go that high pitched.
what, how do you do that????
@@Lou-li5mv it's like whistling but while smiling
For anyone who isn't aware, Tinnitus - for a lot of people including myself - is that very sound, but constant. Never going away completely, always there, often an amalgamation of multiple high pitch frequencies. I've had it for as long as I can remember and notice I often tune it out subconsciously, but when it's quiet around me, it's there.
So this video's coming up on 3 years old but I only recently found it, sorry!
My tinnitus is the same frequency as a CRT. Grew up with it always on and even slept with it through the night. I wonder if this is a cause of tinnitus
Same. I can never have total silence and need background noise just to sleep because of it.
@@kirara2516 box fan
@@professorjack2099 that helps. Sometimes I also have to use a video of a crackling fireplace or rain falling in a forest to help.
i dont have tinnitus but my ears have a genetic thing in that they grew in a weird way that lets me hear higher pitch frequencies than a person with normal hearing, i hate the sound of CRT screens beacause i can hear them, not only higher pitch frequencies but i can hear lower volumes too
yes i do have frequent headaches from this

I'm 33 years old, and I couldn't hear a damn thing at the end. Not with the big hi-fi speakers nor the headphones. I guess 20 years of heavy metal has taken its toll.
I wonder if they are just pulling our legs! What buzz?
@@chocobrowniewin Haha, this makes me remember about my grandparents when I told them their plasma tv is loud.
@@chocobrowniewin
Nah, i can hear it just fine (am 16 years old)
Not only that, it isnt just a random buzz either, its a message in morse code!
(Ow, it really hurts my ears though. High pitched noises are very unpleasant)
Don't worry, the metal is probably not what did you in. It's probably genetic. Someone around 70 I know could hear those rods they use to scare moles away underground, which beeps at the same frequency(or a bit higher) as the end of the video, while my dad(same age) couldn't
I only heard the beeping on my right ear at 25... I guess my left ear is worse
BTW the morse code message is a rick roll
I am 70. My upper limit is now 9000Hz. My hifi stereo system still sounds the same. I guess my brain is filling in the missing frequencies.
Most likely you just lost your hearing so slowly that you forgot what those frequencies sound like. My freinds grandpa has a really good home theater and hifi system in his basement that we use whenever we hang out there, and its kinda disappointing because the calibration and speaker placement is really messed up because his grandpa can't hear well enough to realize that it sounds like garbage due to the way its set up. Its all pretty decent equipment, its just setup wrong.
One time we played an old cassette in it, and I could hear the azimuth was completly off. I fixed it, and his grandpa couldn't hear the difference, while my friend was shocked that cassettes can actually sound really good with nothing but a quickly done by ear calibration.
As you age, your brain starts to make symbolic shortcuts. You think you see or hear something, but more and more of it is memories.
If you can't hear the morse code at the end card, put a portable AM radio tuned to around 530 KHz up to your computer's speakers. You can clearly hear it thru the AM radio. Turn up your computer's volume to max.
geocarey That is absolutely true. Your mind compensates for shortcomings in all your senses. It does this in a way you cannot discern.
Well then you probably didn’t hear the high pitch in the end. It was morse code that said “Never gonna give you up”. At least you’re immuned to high pitched rickrolls, so I guess that’s your silver lining?
my parents used to tell me that i was just hearing things as a kid but i knew it was there, and it was thanks for proving it to me
Well, technically, you were _hearing_ things
No offence, but your parents were probably just too old to hear it. Your ability to hear high pitched noises like this goes away with age.
Don't you just love that? I asked my parents about these things I sometimes get in my eyes. They told me I'm crazy. Years later Michael from Vsauce talked about eye floaters.
That's why I don't have more respect for older people. They often think they've got things figured out and don't want to learn.

@@NahrAlma I've spoken to 50 year olds that still say the world is still an amusement park for them. Still learning silly things they couldn't figure out for decades. You could see how their eyes light up like a young child fascinated by something new they discover. I really hope that love for learning stays with me as well.
I used to ask my parents about the high pitched whine from the television when I was growing up. They were never able to hear it.
As I was watching this video, I remembered of a very funny story of how me and my friends installed an app that allows you to release a constant sound with a especific frequency, and we tested in many ocasions. One of these ocasions was our physics class, where we generated a 17000 Hz sound (very annoying and agonizing sound) and the cool thing is that our teacher was not only old but on top of that, confiscated our cellphones and put them on his table, and for a period of 45 minutes, the entire classroom suffered with that sound, everyone except my physics teacher, that believed the students were being too distracted and finding excuses to leave the class. I could barely hold my laughter.
I kind of want to try this some time
*Some men just want to watch the world burn*
How did I not see you on r/madlads yet
May I know the app name?
Same thing happened too me. Bunch of annoying as kids who play high pitched sounds and the teacher never notices it.

I forgot I'm literally an empath and started crying
@@emilytrost4123 Aww that's sweet :)
@@emilytrost4123 whats an empath?
@@inmiseryseekrootbeer4966 Empaths are empathetic. Empathy = the ability to actually feel how others feel and show a genuine concern for them as if it's your problem too. Like sharing someone's troubles, crying together etc..
I understand it but my asbergers gets in the way often, sometimes I'm only capable of sympathy (which is more like understanding it must be hard/sad for someone and being sorry for them, but not actually feeling how they do)
Sometimes I feel sociopathic were I feel nothing for no one apart from maybe myself. Contrary to popular belief, sociopaths are capable of empathy and can even feel large amounts of guilt/shame. It's more like a switch flips in their mind and they loose touch of empathy. It could be a protective measure to flip, because they can't deal with their overwhelming feelings.
The opposite to empathy is Apathy. Apathy is a common trait in horrible people (such as serial killers & psychopaths) but of course not everyone. Being closer to apathy than empathy can be a sign of childhood trauma - many of us have a tough background, leading to a degree of trouble in our emotional intelligence. It's often that we neglect the importance of our mental health, perhaps, even accusing others of always being the problem when really we need to take a deep and long look in the mirror.
We are not responsible for others and their behaviour, we aren't here to alter them. We are responsible for our own behaviour and the way we response to others, despite how they act.

32 factorial?... phew that's OLD
It's just occurred to me that I might've lost my ability to immediately tell whether or not a CRT TV/monitor was on in a 25m radius, and not even know it, because of course nobody uses those old things any more. I was the same as Tom, could easily do this all the way through my 20's!

Thanks to tinnitus, I have that "old TV whine" in my right ear 24/7...joy...
Im gonna copy and paste this from a page i read a long time ago for a temporary cure for Tinnitus (Although apparently it can stop it with time)
- Place the palms of your hands over your ears with fingers resting gently on the back of your head. Your middle fingers should point toward one another just above the base of your skull. Place your index fingers on top of you middle fingers and snap them (the index fingers) onto the skull making a loud, drumming noise. Repeat 40-50 times. Some people experience immediate relief with this method. Repeat several times a day for as long as necessary to reduce tinnitus.
Does this actually do anything?
My dad worked as a military doctor/surgeon and he says it drives him crazy. His left ear is damaged from the repeated shockwaves.
+Zachary Law covering the ears with your palms so sound amplifies from the fingers hitting the skull? That's interesting what about when taking a shower do the same but instead of fingers you can hear the water dropping onto your skull very clearly.
Yep. Despite being young, I didn't notice the high pitched noise in the video because I thought it was the noise in my head.
NEVERGONNAGIVEYOUUP... Is the Morse code message at the end. Thanks Tom...
Edit: Damn I was too slow xD
i remember turning on the tv in the morning and hearing "PWOOOOOOWW" (i never acctually had a tv as a kid but when i was at my grandpas house there was and still is a almost one meter thicc tv and when you turned it off and put your hand 1 cm away from the screen it went crackle crackle and it felt like tiny hairs touching my hand.)
Omg, you just reminded me of doing that myself. You could also smell it on your hands, was it ozone maybe?
That crackling is just the SUPERMASSIVE capacitor(s) in the CRT losing their 15000v static charge! I managed to discharge one while it was on while poking around in the back of it with a digital multimeter measuring voltages and resistances on the dimmer circuit. Sony Trinitron tubes were the absolute best, but they had a problem after many many hours of on time, where they'd start to go overly bright and you could see the scan lines on the screen as a result, which really sucked. I had a 21" trinitron which I got for free after helping fix a bunch of them with this problem. we hand picked me the best one out of the lot as my payment for all the work I did, and it was that experience which got me comfortable working inside dangerous electronic devices as an adult. I also learned you shouldn't short the CRT's main caps to ground! That was how i learned what arc flash was XD
I loved petting the tv screen because of that feeling
I set up my microphone. I hope that when I play the Morse code it will pick it up in audacity. It does and I'm able to see the dots and dashes. I painstakingly type each dot and dash into a translator (I know zero mores code). All this to get the glorious words of Rick Astley. I think the all energy was worth it:)
why not just download the audio off the video?
Jeremy B Also if you're not into piracy I believe Audacity also lets you record your speaker output directly, no microphone required. so yeah. been a while since I used it though so I dunno
Downloading this is no piracy, it's a legit private copy (at least in Germany it is that way). The only thing you could do is violate youtubes business terms.
Well that was depressing
Fredrico Spalding you know that noise at the end. that was Morse code Rick roll. you got trolled by noises...
The worst part is... I didn't hear that high-pitched sound either :( yeah... getting old sucks. I noticed it a while back when I re-listened to a music cd from years ago and found I couldn't hear the detail that I KNEW was there deep in the mix. :(
richard mattocks What record was that?
I find the opposite - although my ears are ageing, my brain continues to learn and improve. I am hearing more and more details in music.
PROTECT YOUR HEARING - Every slight bit of damage you do is permanent.
That noise in the end hurts
Don't worry; won't be TOO long before it won't bother you anymore...
It's morse code! A special message just for us younger beans. ;)
hurts in more way than one
Am i weird for finding it al little pleasant
I can't hear it
I have the strongest urge to hug you right now.
Mya R same
Me too

I had a feeling "I can't hear it anymore" was going to come into play at some point. I was shocked at how sad he managed to make me about it, though…
When I was younger that noise would give me horrendous skull splitting headaches if I spent too long on the TV. My parents couldn’t hear it, so we assumed it was from eye-strain. It wasn’t until years later, when we got a new TV, but my grandparents still had their old one that I realized what the real cause was.
I put 15850hz into a tone generator. Couldn't hear a thing. Damn. (41 years old)
anthakata 14500Hz is where I top out (37 years old)
The more you age, the lower the high frequency sound you can hear, well in general. Depends on if you had blasted loud music before that age, then it might get lower than average...
I stop hearing at 14900hz (16 year old here)
I couldn't hear the Morse code (age 73) but I can hear a snake in the grass, so I'm not too concerned (loss of high end doesn't necessarily mean loss of other frequencies)
P.S. Actually, not getting rickrolled might be considered a blessing. ;-)
anthakata Remember that the speaker you put it through may have almost zero output at that high frequency. The flyback transformer, on the other hand, has no such restriction.
Anyone pick up on the morse code at the end of the video? I don't know morse code but if anyone knows it and could hear it can you please tell me what it said?
Or am I an idiot and that wasn't morse code at all?
i am wondering the same thing.
I can't hear it :(
I do believe so but I have neither the skill not "Can be arsed"-ness to decode it.
My morse code is rusty as nails, but I think it says "things you might not now", probably? Half the letters I barely distinguish (yes I'm old).
Tom is like the English Vsauce.
James M No, he's not annoying and unfunny.
Tom didn't sell out yet
I like eggs
Wow... All these VSauce haters...
Tom: Just remember, you’re going to lose your hearing
Me: ok
Also Tom: Let’s hurt them necks
This video actually makes me kinda sad.
This reminds me of when I was in Japan where some of the stores/malls had high pitched noises to keep birds and stuff away and I remember my ears hurting when it didn’t bother anyone else.
I thought they used it to keep teenagers away
@@almachizit3207 I don't think that's ethical use of tech
@@planefan082 doesn't stop most shops where I live
@@planefan082 well it’s still a thing people do
@@planefan082 In some places they blast high pitch noises down alleyways to stop teenagers from congregating in there.
I remember always hearing that high-pitched sound when a TV was on, and wondering why my parents couldn't hear it. It would be many years later that I found out what it was. The thing is, I got so used to the idea that TV screens made that sound, that now I imagine I hear it even on modern LCD TVs, which don't make that sound.
if you put your ear to the back of an LCD monitor and move it around at some point you will probably hear a slight high pitched whine from a capacitor. Hell I can even hear my phone in a quite room if i put it to my ear haha
@@TheBanana93 Either I have tinnitus or I can hear my phone's capacitors screaming in pain.
Isn’t it that you might just have tinnitus
Its really kind of a placebo effect. You grow up hearing it and so you expect it to be there
I think I have tinnitus at that frequency but I only hear it when stuff like this reminds me about it. I have decent hearing though. The other night I noticed that my bedroom TV's backlight makes a slight noise when it's set to an even number but not an odd number.
All you kids whining about that noise, just imagine if every video display on the planet made that noise. You don't even know.
Actually you got used to the high-pitch noise, and it started to get annoying only after you got a newer device that didn't emit that noise.
As a kid I could always hear it but never cared. As soon as something was playing it was masked.
yeah I'm used to the sound so I'm able to tune it out naturally when using a CRT yes I can hear it, I simply am able to ignore it
I've never been able to hear it.
If you were close enough to the tv because you were watching it at volume 4 since your parents told you it was time to go to bed, you could hear it
Me: what high-pitched...ahh, I forgot more younger people are here over the years
I came here on a school trip, me and one other child had to walk out because of the migraines they gave us. The adults didn’t know what we were talking about
OMG thank you for this, I always described my Tinnitus as an old TV screen ringing and no one knows what I'm talking about!
lalaland I've had tinnitus since I was a kid, and I always described it as an old crt turning on.
wow PPTA and lalaland. Found someone like myself!
KT just try not to go insane if you're in a sound-free bedroom. Like always turn on the fan or something so you won't get annoyed.
KT, I also only remember I have tinnitus when someone mentions it, but mine is faint enough that it doesn't bother me even when I notice it.
I can't tell whether the high-pitch sound is coming from the video or my tinnitus. I'm just going to pretend it's coming from the video so that I don't feel old.
What's the high pitch Morse code at the end of the video say?
Jack O'Rourke it says 'Never gonna give you up'
-. . ...- . .-. --. --- -. -. .- --. .. ...- . -.-- --- ..- ..- .--. = nevergonnagiveyouup ... yeah thats what I thought
"NEVER GONNA GIVE YOU UP"
"Never gonna give you up." We got rickrolled.
Those used to drive me bats, when I could still hear it. And speaking of bats, I could also hear bat sonar (not joking). That was some time ago.
Well, I guess it's hard to tell if you're watching this on a CRT.
You just had to put in that bit at the end...
Well, at least it wasn't that image from that video that Tom used as a thumbnail for another video and had to apologise for using that image from that video. That would have been really annoying...
_"I don't shut up."_ ~Tom Scott, 2017
HEY WHY DO YOU INSERT THAT HIGH PITCH SOUND AT THE VERY END YOU CAUGHT ME OFF GUARD!!!!!!
tom: at least you can still hear it
video: beep boop boop beep
me: *IT HURTS, MAKE IT STOP*
That beep beep beep in the outro is morse code, which translates to "NEVER GONNA GIVE YOU UP"
@@allaroundwindows7794 WAIT REALLY
@@allaroundwindows7794 I thought I heard something and was going to ask if anyone could check if it was morse or binary, seems you already cracked it!
@@allaroundwindows7794 I just checked and you're correct lmao
It sounds like Morse code but I don’t know how to translate it
Anyone who likes to attend concerts fairly frequently: custom made ear protection is more than worth it!!
you know how the sound gets worse towards the end of the night? That's not the sound, that's your ears. With custom made protection it will sound better all night long.
I used to carry gunrange earplugs to metal concerts, and my friends laughed at me. Then the following days they wondered why their ears kept buzzing and I laughed at them.
Matt & Tom on the Park bench did an entire video about this, if I remember correctly. Every time they have to work somewhere loud, they bring ear protection.
Salah Eddine H That video is linked in the description.
Dear god, those last 10 seconds are *agony* on the eardrums!! D:
I KNOW! SO LOUD! D:
It's morse code spelling out "NEVER GONNA GIVE YOU UP".
Guess I didn't get Rick Rolled then - couldn't hear it.
Well, I guess I'm getting old. Last 10 seconds? Completely dead silent to me. Didn't hear a thing.
be glad it wasn't agonisingly painful.
Never gonna give you up. That end tho, I just got rickrolled by a high pitched screech
I am really sensitive to high pitch noise for some reason. I go around the house unplugging wall watt powers supply's because of their coil whine. My family thinks I am crazy though.
I have that too!
Will That is annoying. And only I can hear it too
I hear lamps buzz beefore they light
i have a ps4 in my room and i literally cannot sleep if it's plugged in, even if it is completely turned off
Now that you mention it, I think I was like that (to a much lesser extent) a few years ago, and now I don't notice it
Was that some sort of mores code beeping at the end? or am i imagining things
i heard it as well, and now it's stuck in my head.
It says "Never gonna give you up". We got rick rolled.
oml does it actually/ Well he's done it before so I wouldn't be surprised by this point XD
WimpyVids bugger I did not hear that.. #gettingold
I couldn't hear it :/ I'm only 21 haha
Tom: "Protect your hearing"
Also Tom: *Plays ~20kh noise at the end of the video
Thanks mate, good to know I can still feel this pain at age 24.
I'm 15, and I was baffled when I realised I couldn't hear it. But then I realised my headphones just filtered them off. Hopefully.
Yeah. Specially High Fidelity headphones often filter out extreme noises to protect hearing.
You're halfway to being 30.
I’m your age and I’m not wearing headphones, still can’t hear it, oops
That's a pair of very shitty headphones you've got there.
Im 19, and just found out only my left ear can hear it soooooo
"Anger is fear in disguise". Now that's a quote I shall never forget, thank you.
FYI, hearing damage is permanent and accumulative. Always have ear plugs on you and never be ashamed to use them.
How can I tell what noise is damaging?
I remember the big CRT TV we had when I was a child. I hated watching movies on it, as it was so loud (the noise). Some weeks ago I was on vacation and the hotel still had CRTs, but they were really quiet somehow. Sadly I forgot to check the frequencies with my phone, but I am able to hear really high noises and all other CRTs, so that somehow was a special one. I can also hear the morse-code in the CRT-pitch at the end of the video perfectly fine.
