Isolation and dementia - Why we should protect our ears | DW Documentary
HTML-код
- Опубликовано: 21 авг 2024
- If you’re young, you don’t usually do enough to protect your hearing. But more than a billion youngsters are at risk of hearing loss worldwide. People often turn to assistive devices when it’s already too late. Hearing loss can result in isolation and accelerate the onset of dementia.
Traffic noise, aeroplanes taking off, music turned up to full volume. At concerts and parties, noise levels often exceed the pain threshold of 120 decibels. This can lead to noise-induced hearing loss - damage to the ears that can’t be cured. Age-related hearing loss is different: in this case, hearing aids can help. The first signs often appear in people when they reach their mid-40s. Those affected can no longer hear high frequencies and have trouble following conversations in a noisy environment. This may mean that people withdraw socially.
Hearing aids filter out background noise such as traffic or wind, suppress reverberation and amplify speech - all depending on the listening environment. Nowadays, the necessary technology fits into tiny casings. However, there’s still one disadvantage to all these hearing systems: the loudspeakers close the ear canal, which leads to sound loss as well as potential inflammation. With the "hearing contact lens", on the other hand, the loudspeaker sits directly on the eardrum and stimulates it directly. The start-up company Vibrosonic says that as a result, the sound is clearer and stronger. Could this be a viable alternative to traditional hearing aids?
We introduce young people suffering from hearing loss as a result of listening to music too loudly for too long, look at everyday situations that put extreme strain on our hearing and present new solutions from the hearing aid industry.

I will never understand why cinemas and concerts have to be so loud. I OBJECT!!!!
I object , music must be loud to wake up the heart 💓 and the rave that u get is speechless way to express live
I understand concerts and raves but not street buskers. They pull out a nice guitar but absolutely deafen the entire street with the amplifier!
Or amplifying naturally loud instruments such as drums and saxophones. It's a headache working in a pub with live music fridays. Five months and I quit!
This documentary got me so spooked that I have decided to watch the rest of it on mute.

That's what captions are for.
A world without DW is boring. Thanks for helping me in learning English while I'm enjoying your exciting stories and documentaries honestly you made the learning easier. Thanks to you I got My IELTS exam and made it to Canada. Big heart
Thank you for watching! We’re very glad to hear that, congrats!
Also using DW to learn some english❤👏 thank you DW

Just please, don't get excited about their ecopropaganda
Even more when the DW targets are in countries outside Europe
@@r.guerreiro140youre right, I've also noticed that as a common eastern european
I'm not sure about this comment...
It's only relevant for people who have teeth
I appreciate all the work that is done for the people with impaired hearing, but more work needs to be done in mitigating noise pollution and other causes of hearing loss. Good documentary as usual, DW
Thanks for watching!
I completely agree! As for many other diseases as well!
You know what we need? Drone delivery, everywhere!
Louder lawn mowers, leaf blowers, and weed whackers!! >:D
2020 and the reduced air traffic because of COVID....months of little to no air traffic for months was truly amazing.
DW Documentary does a fantastic job. It's like studying plenty of global subjects for free. Worth to watch according to the time we spend on RUclips ❤🎉
Strongly agree.

What?
Fascinating. I moved to a small town in Sweden from a busy part of Budapest over 5yrs ago. There I lived in a big house with several flats with constant noise almost 24/7. Most annoying time was during Summer when temperatures forces you to leave the bedroom window open but people passing on the street under your window talk and laugh loud during the night. I woke up to every human sounds.
Here in Sweden I live in a quite residential area with lots of families and dogs yet nights are so quiet as if I lived in the desert. People respect others’ privacy and rest, and they train their dogs so there is hardly any dog barking even during the day. It’s absolutely amazing. I almost always manage to sleep through the whole night without waking up to any noise.
We need to be more considering towards others.
Thank you to everyone who is contributing towards a better future for these people. The advances in science and technology fascinates me. I hope one day tinnitus will be something that will be able to be cured or healed. I value silence so much and have never thought about how much I took it for granted until it was to late. I think the health of our hearing is just as important as everything else therefore should be taken as seriously as everything else. This brings me joy and hope. Thank you DW for educating us and teaching us this knowledge. I truly do appreciate it.
many forms of tinnitus can, but many are told by their physician it's untreatable. It often is, but it's not emphasized enough: go to an ENT if you are experiencing tinnitus!
@@hangedfox9286 very true. In my case its untreatable, I've gone to a handful of general physicians,ENTs, and audiologist. They have all told me they don't know what caused it so I've been told that I will have to learn to live with it. I do agree with you though. Always go see an ent, general physician, and an audiologist. They dedicate their lives studying this and I'm sure over the years new treatments will become available as technology and science advances.
This was a great documentary on so many levels. It helped us understand the risks to ear health even among the younger. It educates about what those with hearing loss experience socially. And it was inspiring to see the incredible research of medical experts, scientists and technicians. Thank you again DW for great reporting.
Thanks for watching and sharing your thoughts!
I was taught around 3 years old never yell indoors. It’s not necessary. Use your indoor voice. Don’t run or chase in the house. Certain activities make children want to yell and scream so those activities should be done outside not indoors but no one teaches their kids these things anymore it seems. Not to talk or make a bunch of noise while people are on the phone or talking to adults, you go play and be quiet about it, don’t interrupt unless it’s an emergency. There’s nothing like having an important conversation and a 5 year old comes up and keeps interrupting talking about nothing really. Many adults think they would be looked at like they hate kids if they told them to pipe down. Well then deal with the stress.
Okay, thanks for that info!
Documentary no doubt goes beyond. Thanks for a lovely education.
Thanks for watching!
I've come to appreciate my hearing much more after finishing the documentary and absorbing all the sounds including 19000hz
Thank you DW, every time great documentaries.
Thanks for watching and taking the time to comment.
Extremely useful video explaining everything about Sound,Noise, Hearing, Hearing loss, remedies and why we should protect our hearing ❤
Thank you for your comment!
Certainly a good precautionary mini documentary... I freaked and turned the volume down on my ear buds! Really appreciate this channel and all of the great topics ♡ it's also enjoyable to see the innovation that is being used to tackle these types of issues!
Am struggling coping with noise for a long time .If I could I would move out into the forest away from people.
I did, sold out and bought on a forest reserve.
@@elzaaltmannwhere there is WiFi?
@@thechansfamily No, but there are data package deals, so I use my tablet. I can surf the net, watch you tube. No tv. But I can hear nature at its best. I am lucky I guess.
Have you been diagnosed with hyperacusis?
Can I come, too?? Silence is golden. 🌲
I lowered my volume after clicking on this video 😅
Most valuable and knowledge thing that I found on u tube is DW documentary, it is 💯... Really worthful...
I began using cheap, spongy earplugs from the pharmacy. It was 30 for $10 I think. They help me sleep and maintain some sanity when traveling. They let me frequent rock venues and play my own music too. You learn to hear THROUGH them nonetheless, it raises your visual awareness. Mack's Earplugs are the best. But whatever you find, reuse and horde them for later.
Great connection you've made! A few years back when I was getting pretty stressed and whatnot, I came to a realization one day that I was so over focused on my visual awareness and what's in front of me, that I noticed how much had stopped taking attention to my sense of hearing. Which therefor made me focus on my ears more, correcting my posture, and slowing down my pace and stress levels, due to hearing my inner monologue more clearly!
wax ones are far better than sponge
Appreciate the sharing of your personal experience & knowledge! Before this video, I had very little awareness of what Noise levels could do to me.
Foam ear plugs can be washed and reused. The will inflate in size many times, and by absorbing water they will expel contaminants when pressed with cloth to dry.
Admittedly this is only anecdotal, I do not know how well they maintain their protective qualities, but the process exists.
Be safe!
26:00 Can’t hear 16KHz but can hear 19KHz very well
Make an appointment with an ENT doctor ASAP 😂
I think they forgot to include the sound for 16KHz. This was the only one i couldn't hear, also.
I searched for a website and was able to hear the 16KHz very loudly
Same here
Haha me too
Also
A BIG THANKS to DW Channel
DW are the best, thanks for that informative documentary.
Thank you for your comment!
Great documentary.
We often forgot that in the information/digital age, visual information is not the only way to be overloaded. All this easily accessible entertainment like music is problematic.
I'm optimistic about the future, I have a feeling awareness of information overload will drastically higher than now.
Thank God for closed captions.
Highly recommend documentary to watch
and listen to
Noice and disturbing sounds must be the reason why office landscapes are so popular. You get so sharp and creative in such envorionment, no stress, all joy!
lol!
Great documentary as always,Thank You DW✌🏽!
Thanks for watching and taking the time to comment.
I listened to a lot of music, all the time, been shifting to full silence even for mundane work, helps with ease, but habits will fight, stay on it to experiment. Much love and care to YOU, stranger.
DW, can you please do some quality documentary about TINNITUS, "ringing in the ears."? Millions and millions of people are quietly suffering from that, in many cases untreatable health condition. Is there some serious scientific research going on right now? If any? Thank you.
This can also be a result of severe magnesium deficit.
Causes can differ from person to person which is why it is so difficult to treat. Doctors are still people who can't know everything.
I'm getting a lot out of this channel. Thank you all so much!
Thanks for watching!
Fascinating and extremely underrated topic. Now I understand why in Germany there are so many hearing clinics, next to eye clinics. We should be more aware of our sense of hearing...

Content is primarily in English, stands to reason many engaging in the comments speak the language. As such, if commentor is able to express themselves in English, it's just preferable they do so. And yes, I know about CC and RUclips's translation features.
Why are hearing aids SOOOO expensive? I mean they are about 2,300 euro for a low end pair, and they only work well for about 3 to 4 years.
I suffer from noise, terribly painful. Could we teach our children to quiet down, instead of screaming all the time?
Not the children, the classroom instead outside in nature. These brick/concrete rooms reflects (compresses sound to higher levels) that is the real problem. naturally we love loud sounds of short peaks and long pauses like music :)
@@robfontijn1406 In general, there is too much noise, especially when alot is going on. My parents always curbed our noise as children. We make excuses for them. No need for yelling I would say to mine, I am not deaf.
@@robfontijn1406 you can, and should, definitely tell children not to scream and shriek. It's called learning to be considerate of others.
We were not allowed to just scream like banshees. We were taught that many people around us are ill. You're upsetting animals, et al. Kids don't need to scream like that to enjoy themselves. Ridiculous!
That's not compression @@robfontijn1406
I feel the DJ, but I was lucky. I do hear a constant very high frequency on my left, but when there is not much noise in the environment. Take care of your ears or you may not be so lucky. Great work DW, thanks for this nice doc.
Thanks for watching and sharing your thoughts!
A really great documentary, I learned a lot about the new technologies in restoring hearing, which are all really exciting and promising.
Impressed by information that cochlear cells can be sensitive to light. No mention of ossicle function and the small tensor muscles that protect the ear from loud noise and then failure when the joints between them wear out. No mention that cochlear function is not simple resonance and requires complex neural processing that itself disappears quickly as hearing-loss progresses. Early use of hearing aids helps preserve this complex neural processing. Wishing that all DJs and movie-houses understand the difference between total power and peak-to-peak intensity of large loudspeakers.
Wow. I was listening to this on earbuds in a noisy cafeteria. I had just turned the volume up and dismissed the phones warning about listening above recommend levels. ....makes a guy think.
Very valuable . And I realized value of appreciating and being greatful to ourlives and see the good things we already have that we are not much considering like our good health , eye sight , hearing , speaking and moving abilities . In away these are the most and greatest profit in our lives than any other thing like lotof money, fame and power. So lets be greatful everyday for what we already have without being too late .
I live alone, avoid concerts and all mass human activity in general. I should be good.👌
9 years ago, i started having tinnitus. I listened to loud music through my adolescence while wearing cheap Chinese plastic earplugs. After hearing the tinnitus, i never used earplugs again. I avoid loud events. I have to be careful. My right ear is unbalanced and had massive vertigo attacks. The crystal inside were screwed. I had to do special exercises and diet for a month to heal.
Excellent documentaries
DW, I love your movies so much. Thank a lot.
Used to work in a car shop. Loud noise was also one of the reasons I quit.
My little brother screamed in my left ear a few years ago. Ever since, occasionally, noises from my left come with a crackling - like what happens to a microphone if it's recording something louder than it can actually record. It was quite common for a while, now it's rare.
One scream has had a impact lasting years.
I actually took my earbuds out and enjoyed some silence just now before watching this...
It's kind of ironic though that we are using our headphones to listen to this.
I've only experienced silence once in my life. During a soft snowfall in the upper basin of a mountain range.
"None of our senses Are as sophisticated as our hearing . " Except the senses you don't even realize you have
This is scary me as someone who wears headphones a20 to 24hrs a day.
Acoustic panels on the walls could help in classrooms.
Weird, I heard the 19k Hz tone but not the 16k Hz one.
Same wtf 🤔
Myself as well, initially I thought it was the frequency response of my phone speaker but with headphones still nothing. Then I read another comment with other people agreeing and one person speculated that perhaps that sample was accidentally left out of the final edit.
One good thing about dementia is that i keep on watching old western films again and again to pass my time
Yup...can watch any film you liked again and again and enjoy it just as much... 😊
Silence has become a luxury
thatz why I don’t club or use headphones allmost never, silence is better for mind and soul
It is an eye opening for new technologies in horizon....but still there is a dilemna...hearing loss with aging... don't blame on noise pollution because there are something else associated with aging that still eludes us..
As people live longer, this will be a challenge to medicine and technologies to overcome it so millions of seniors can enjoy their times remaining on earth.
You raise a very interesting point, longer life expectancy & the resulting durability expectations on our bodies.
My guess is eventual bypass of the eardrum thru to auditory nerve system. As I understand it, regardless of the type of hearing aid there is still reliance on the hairs & nerves, which eventually deteriorates.
As much as I disagree with, bc of the high likelihood for misuse, something like the brain implant Musk & co have developed may serve the purpose.
But in all likelihood I misunderstand fundamental constraints, being an outsider attempting to look in.
This is an excellent video.
I didn’t realize how loud I listen to RUclips videos until I watched this one
I value my healing. Always use foam earplugs when operating machinery on my farm.
I really appreciate using my cordless electric chainsaw. It is so quiet you can talk with other workers, which increases safety. I often use our EV to pull trees down, which as the same benefits. Look forward to getting an electric tractor in a few years, or making one.
I've always wondered why we can't "blink" our ears.
When my child was born, they came and tested her hearing within a day of her birth. Her hearing was good. I wondered how that test was supposed to work.
I have hyperacusis, so sounds feel louder for me than so for the average person. I wear earplugs often because things are so loud in public. I can hear electricity especially when I'm charging electronics. I also struggled in situations with a lot of other noise, like a party.
When I listen to music on my phone, I'm on the lowest sound setting on my phone and it's still too loud for me.
It never surprises me that when I meet a woman who works with children yet never wants to have any of her own. I understand completely.
Yup
isn't it based to judge from working with only a certain range of age? Would give you a perspective that they'll be like that their whole life, which some are, but most arent
its like how cooks never want to cook decent food for themselves once they're off work. I could never understand, should be the other way around if you ask me
I'm trying to become a midlife mum. I don't know any children. In fact, I have no idea if I even LIKE children. I figure that I'll only have to like and love my own child.
I always thought that my hearing loss was due to loud music and popping my ears when flying. An ENT doctor told me it was from ear infections through out my years. I’m thinking now he didn’t have a clue! 🤦🏽♀️
I go to about 10 music festivals a year and religiously wear eargasm ear plugs . They still allow the mids and highs to come in but at 20db less . I’m there for the bass anyhow and always leave with no more ringing in my ears or pain .
Always had difficulty understanding people in noisy rooms. I'd like one of those "focus" systems to hear my conversation partners plz
If you are subject to very loud music in discos or at rock concerts/music festivals and are also intoxicated on alcohol or relax drugs like ecstasy then the damage to your hearing can be even greater-- under normal conditions the ear muscles close in to protect the ear drums etcetera but alcohol and drugs prevent this protective mechanism from kicking in.
I never did like clubs or bars for the same reasons
Very informative documentary about hearing and hearing aids but I find the title misleading; there was no discussion about a link between impaired hearing and dementia which is what I was hoping for.
New DW video. Turn the volume up!
😂
if it's safe for me to assume that children have the best hearing, why are they so loud?😂
The content is very good
Is it possible to have vertigo without hearing loss.
There are exercises to eliminate vertigo. I’ve done these exercises and it took care of the vertigo. Seems to me hearing aids don’t improve your vertigo. Check out the video by Carol Foster MD. Her video shows the exercise needed to stabilize the crystals in your ear tubes. It worked for me. Anybody who has suffered from vertigo and use these exercise well benefit and wonder why they did not find out sooner.
A strange thing about vertigo is, if you stand right next to a tall building and look up, do you feel vertigo?
Vertigo, or BPPV? I have the latter - for me it was caused by a wakeboarding accident and trauma to the head. After that I developed BPPV. Doing the “epley manoeuvre” helps to move the loose crystals to a location where they don’t cause problems. For me, it only comes back once every 18 months or so. An anecdote only, but the last time I had BPPV, I swung upside down on gymnastics ring (I work out on them every day) and it went away immediately (I didn’t do the epley manouvre that time). Worth a try if you have the problem. But epley manouvre is generally effective, but it can take a few days for it to go away completely.
I'm in my mid 30's. I couldn't hear 16000hz, but I heard every other frequency. I don't know what that means.
It's great to see the progress being made to rectify hearing loss but there was not much on any leading research into tinnitus. Life with cicadas in your head is unpleasant and unending.
Every time I hear a loud noise, I’ll be able to visualize my little ear hair like things falling in battle
DW makes documenatry about how harmfull noise can be. Proceeds to demonstrate every harmfull noise at length and loud.
Yea, ouch!
I feel like I always need music playing instead of silence.
Nice and interesting..... pollution is in everywhere... Sound... Vision.... Intellectual...and so on....👍
25:53 Why I can hear the 19,000Hz and 15,000Hz waves but not the 16,000Hz one? Did the software converted the waves?
Same
Same…
Even if DW produced the sound correctly, you still can't guarantee if RUclips will process it correctly or if the user-side software and hardware will output it correctly.
The test is only useful at calibrated machines in the doctor office.
A noisy documentary on noise. At various points i had to hit mute.
40:45 Now if you listen the English dub really carefully.... the dub man might not know who you are and what you want, but he do have a very particular set of skills that he acquired over a long career.
Unfortunately my ear already damaged by my job working on agriculture sector by grass trimmer now I use ear protection. I had been exposed to loud sound for 4 year
Have missed an important part that how to protect our hearing
I have had a high pitch tinnitus 24/7 for many years and I suspect it's induced not only by loud noise (I used to work on sonicator without ear protection during grad school) but also by regular, intense meditation I have been doing. Does it bother me? Yes, especially at the waking time in the morning.
Why would regular, intense meditation cause tinnitus?
@@raksh9 check out meditation-induced tinnitus. This is not an uncommon phenomenon among seasoned meditators.
While in Hungary in Kerox people work without any hearing protection in a hall full of very loud automated machines. There's a box near the entrace with cheap earplugs but you aren't encouraged to use them. There's also a work process when they use ultrasound for cleaning and staff does that also without any protection.
Soviet era custom
@@somozasi I think not. In soviet era factories had libraries and a very own kitchen for their employees. This is capitalism in it's purest form. We just toil to earn enough money for our employers to go on a hunting trip or on an ocean cruise.
@@sage_silvestris a kichen doesn't protect your ears !!!

Yes it is the same for me. I think they did not used 19000Hz but some lower frequency maybe 14000Hz at the limit of my hearing.

Since 3 years I do experience the same ears problems that you are talking about ; maffle sounds ,vertigo ,tinnitus I was never exposed to to loud sound !!! (?)
I think Hearing damage, and Brain damage go "Hand in Hand" 😂
38:18 That knife handling though 😱
2024: If only common sense prevailed in the world over the past half century for this topic, but then again there's common casual ethanol ingestion so what else can I say? I was one of those "sensate" children that covered his ears when my dad ran his table saw in the garage. I've been to small-town parades here in the US where they celebrate by igniting vintage cannons rolling down the street. Incredible how children are left to sit just 20-feet away from rolling machines that otherwise probably damaged the hearing of soldiers, not to mention the "shaming" by peers of not enjoying loud music as a teenager. It was literally painful, what else can I say?
All those unprotected youth working in fast food restaurants. The excessive beeping of all tthe cookers you hear in those places are abusive to their ears surely.
I put headphones at work to listen to classical music but after a while it doesn’t feel comfortable anymore. Luckily the office is getting quieter lately so I don’t listen to anything anymore it feels better without earphones I don’t know how some ppl put earphones on all day I can’t stand it
My experience if someone have bladder or kidney problems or urine infection have hearing problems.
Thanks
I went to the shooting range and used cheap 3 dollar ear plugs bought at a military post exchange. I now get a low and high pitch ringing in my right ear that never goes away. It bothers me when I sleep.
as a deaf sometimes people told me that I'm not good at listening
Great 👍🏻

This is a condition of noise sensitivity called hyperacusis, which is often related to tinnitus.
Yep.. I wear earplugs most of the time... everyone is so loud.
My tinitus started after chiropractor adjusted my neck.
Went to chiropractor some time ago just to see what that is about, not having any problems but told by a friend that it maybe beneficial in my age. Have a stiff neck ever since
good to know what's coming in term of technology assistance. never in life I imagined a contacts lens for eardrums. however, as each technology has it limitations or specific purposes, I don't think te contact lens would fit to someone with damaged cochlea. so, it's seem that the technology for IC hasn't advanced that much compared to others aids. in that sense, I think we are very far from closing the gaps of hard of hearing feelings being part of the rest of community.
