Also, in retrospect, it’s pretty fitting that Audible (an audiobook company) is sponsoring a video about listening. Didn’t intend that but it’s neat how things work out.
Well, i could understand bits of both, but no matter how hard i tried, i could never fully understand both sides. But i suppose i also have it kinds more difficult as an enlgish non-native speaker
Dude, i love when your videos, and when you make references. Why do we actually love references?🤔 (wish someone made a video about that)
have a few cocktails and then see how your cocktail party ability works. For me it stops working quite soon.
I could understand the middle clip and right clip. For some reason I couldn't understand the left one.
I tried without headphones and it was very difficult, most notably when hearing 3 voices at once.
But I think it is understandable, taking into account it was the same person speaking 3 times, and that english is not my mother tongue.
Also, you included my last comment on your video! =O
It's easier when they don't have the same exact voice
*HEY VSAUCE MICHAEL HERE, but what is here and HoW mUCh DOes iT coST??*
Ok, time for a little infodump here:
I'm autistic, and for me part of that is having APD(Auditory Processing Disorder). I always use the Cocktail Party Effect to explain what APD means: what your brain does automatically when you focus, I need to put conscious effort into, and even in the two person case, I need help from being able to (somewhat) read your lips to be able to pull your voice out.
Simplest way of phrasing: "My brain doesn't have the filter yours does".
There's also basically no difference between viewing your video with stereo or mono sound through my headphones(ie: split or head-on voice directions)
I need to consciously pull all the tricks, recognizing partial words, phonemes(including the lip reading above to make sure I got the correct one), etc. Attention(in the sense of automatically discarding information that's not relevant as you talked about) is also manual: if a voice is loud enough to pick up words from, I need to dedicate a lot of energy to discard that instead of having it interject the words the speaker I want to listen to is saying.
This means noisy environments are intense and really tiring, and also that audiobooks or podcasts, when listened to in any environment where background noise bleeds through my noise-cancelling headphones, are going to involve a lot of rewinding bc I missed key words.
(Feel free to ask for more details if you're interested)
Looks like I'm a mad lad
The maddest of all the lads 👌
These are so well researched and you have so many references to other people I watch. Glad to see an inspired person.
Ah, I always knew I wasn't superhuman 😝 wasn't able to follow either of the two / three, but I also have a lot of trouble following what people say in noisy environments despite having good hearing
Good hearing as in being able to hear sounds well isn't the same as processing voice well. Two very different skills your brain has(if neurotypical). Ask any person with Auditory Processing Disorder(like me), being taken to hearing specialist after hearing specialist as a kid, only to be told my hearing's completely fine(while not being able to follow any conversation in a noisy environment)
I had to try really hard to hear anything but the rightmost video in both cases. I was confused as to why this was until you said that you separated the audio into separate channels. Due to have damaged hearing in my left ear, the right video was always the clearest. Super interesting! I guess I know how to better focus my attention now, point my right ear toward the person I want to hear!
Informative, entertaining, and funny. You deserve way subscribers than you have. Keep up the amazing videos Alex!
I was able to distinguish between all three, and jump between them. I didn't know that that was something "special", I tend to be able to hear and understand conversations happening around me even while I'm engaged in another one.
does hearing a lot of voices at the same time stress you out? or do you view it more as a good ability you have?
I guess I treat it more as just an ability. I don't really mind it, and I can tune them out if I really need to focus. But if I'm talking with someone I will also be at least partially aware what's going on in the conversation next to me.
Ok. I'm not good at focusing on one conversation. I hate big parties because of that!
v Zuijlen you and me both
Thats some fantastic hair
+Thomas Frank sent me. So glad he did! 👍
While this theory was still being worked on, one psychologist was convinced that this only worked because of the physical separation of voices (left ear vs right ear). His students thought that the meaning was more important though, so they set up an experiment where you were supposed to follow one of two sentences. Each sentence would start in the L or R ear and switch ears with each word (so sentence one went LRLRLRL while sentence two went RLRLRLR). the participants were still able to follow the sentence they had started with because meaning and our understanding of language plays a more important role than the physical L/R separation of the audio.
I learned this from my psych professor so I unfortunately do not have a source lol. Nice video!!
Also Daniel kahneman an TFAS are simply superb
Audible sponsors everything with a pulse. (Pulse optional)
hey great video.
something you did not touch on but that helps very much is seeing the person. i had no problems understanding what you said in all the clips when focusing and looking at the matching face, but looking away or even looking at a different face talking it gets much harder.
i think a important part in the cocktail effect is your brain not only taking to account what you hear but also combining it with visual cues.
another interesting thing your brain does when what you hear and what you see don't mach is the McGurk effect.
have a nice day
Definitely think you should be up there hanging out with Michael, Destin, Steve Mould and similar folks. *heads off to Patreon*
Yasssss another vid love these
Hi, loved the video, but as a psychologist I would suggest having three different voices speaking simultaneously, as it is almost impossible to distinguish particular speech spoken by the same person, creating a floor effect in your experiment.
Now if only i could get invited to a party to test this out
I don't really have that power, I have a really hard time filtering sounds. It partially works with 2 for me, but with 3 it's just gibberish to me.
I never knew this had a name but I always like trying to listen in on multiple different conversations in a loud room. A brain exercise AND a way to listen in on the tea
The Jacksfilms and Gus Johnson references cracked me up! Keep up the funny and informative work! :D
I usually read the description all the way through after videos. I grab links to videos you use or talk about and depending on the subject I will grab sources to read through. So yes, some people do.
good data thanks man
Great video as always, my friend!
I think I'm broken. I couldn't do this at all. Probably why I do so poorly in noisy environments
Edit: maybe my brain just doesn't have enough capacity to do this as easily as others. Being in even moderately noisy places and trying to hear people really stresses me out... For multiple reasons... but partly because I have such a hard time understanding. It's frustrating
Mu51kM4n First person in the comments I've found that also couldn't do it... At least I now have an excuse to tell people when I ask them to repeat themselves 20 times in a busy place.
Not broken, just different 👍😊
I understood very little both overlapped and were indecipherable from each other. This holds true for party’s and other large gatherings. I can’t hold a conversation during one because I am hearing and processing everything in the room equally. The words and sounds blend together and It gets overwhelming whelming quickly. I’m going to look into it because I didn’t know others had this ability. The lack of it might be an autistic trait.
i tried a few times, understood nothing from either. i have ADHD so i guess it means im by default deficit of a superpower😅
@@cjk705 you are never going to believe this but i also have adhd
5:45 nice
At least, now I know in what ear should the only working side of my earphones be.
I just found out about you from Thomas Frank's weekly email and I'm glad he recommended you to us!
I absolutely love your videos! You do a fantastic job with all the research and then presenting that research to all your viewers. It did work for me, I could understand what you were saying in the right clip and in the left clip! Super cool!
This video is chock-full of references that I don’t understand.
I watched your Hamilton video which was posted 2 years ago and did not expect puberty to hit your voice so hard
I couldn’t unhear the first clip I listened to! Anyway, this is a really cool topic I made a powerpoint for my neuroscience class about after seeing another video about the effect.
Buddy love from Pakistan..very funny way of teaching❤
We have the same name and age, we both like science and that Hamilton playbill is making me jealous
Are you my lost twin or something? (?
Also, I love your videos🖤
So today I have a presentation on The Cocktail Party Effect. And your video is so well put together!! It surely helped me understanding the topic (and saving my day😅). Thanks for the amazing video!!
That comic in the corner at 4:40 is "LOSS", a comic part of the comic-series CTRL+ALT+DEL by Tim Buckley
That was frickin' golden.
Dude!! I just saw a video of you about halloween in 2016. And here we are! Such a cool channel..subscribed!
Awesome I heard all 3 while my 2 year old was playing in the background.
I could decipher between the three voices without headphones, just my laptop.
Wow, I am so much worse at that than I think I am. While listening to the first two voices, I was all "Wow, I actually understand what he's saying, maybe except for a few words here and there, but still, wow!", but when I read the transcripts, it turns out I caught less than half without even realizing that I missed so much. At least when there was three voices, I was self aware enough to realize that "Christ, this is just noise to me, wait, what was that about the Bee Movie?"
I luv how u r using a type of theme for the video picture! And u r getting sponsors too! Thats great
Awesome video on a curious subject. I also love the Gus Johnson reference.
Excellent explanation my feathery friend.
You explained it so well! Thanks a lot!
You're awesome dude! Needs more subs
So for the three voices, I could distinguish the Bee Movie hive and Vsauce intro to talk about what is here, the third (middle) one I was barely able to catch what it was fully saying with the other 2 going on at the same time.
EDIT: Now that I finished watching it I really like the video! I especially like the Jacksfilms and Gus Johnson references keep it up you deserve more subscribers
I only understood somthing when I watched the right one. But I am one of that kind that struggle to follow one conversation when many people talk at the same time. Probably because of I have been nearly deaf on my left ear several times from childhood to grown, and still have damaged hearing on my left ear.
Last time I was deaf, almost all of the eardrum gone, about 2014 to early 2017, got a new eardrum late in 2016, and started getting usable heating early 2017.
I don't need hearing aid, but I think my brain still have not reprogrammed to filter conversations in a good enough way. But seeing the persons lips and expressions helps filtering.
I don't think most people know about it or think about it whitout having a hearing loss, but all people can read lips and expressions to a degree to aid hearing. Assuming you have good enough sight.
A more lenghty post than I intended, but I have never tought much of my lack of this ability this way before watching this video.
And going from mono to stereo hearing after 2 years was a weird thing.
when you dropped in 3, I was trying to focus on the one on the left, because going left to right, but all I could hear was THE BEE MOVIE..... Which means, my brain recognized a meme and focused on that as more important, because apparently bee movie memes are bigger memes than hi, vsauce, michael here, or at least higher on my brains priority of memes.
awesome video like always! i leave feeling very informed
It's interesting. When I watched the video on my smartphone, the right one was clearer and louder. Now I rewatched it on my laptop and the left one is louder and clearer.
But then again, I know now, what you are saying, which makes it far more easy to understand it. Since english isn't my native language, it's harder to focus and understand it, probably because I'm not that familiar with the phonems.
Do you know if there is a name for the effect where you're not listening to someone that says something, but then you play it back in your head? (Usually after going- "Huh?" then before they start to repeat it you go "oh, yeah.") My sister and dad do this as well as others I know (but not my mother).
Halosty This is me all the time - it'd be cool to know if there was a word for it!
This happens to me a lot.
Yeah, bad habit :d
My man knows what he's talkin'
Yeah, I can't do that... attention deficit disorder , I can't focus and yes I tried it a lot of times. Some (or all/ have not enough data to know that right) autist have this problem too.
Have a nice day and a better life.
Ah, SO cool! I'm a hobbyist audio engineer so it's cool to see something that plays with my audio perception. 👍
I can't understand either. This is one reason I don't go to parties.
I heard the right one both times but it was clearer when I focused on the face.
loss is a beautiful meme thank you
Dude, i love when your videos, and when you make references. Why do we actually love references?🤔 (wish someone made a video about that)
My ability within this superpower is severily limited. Using it gives me a headache and I noticed now that I can only either concentrate on the stuff to the right of me or focus on everything at once
This makes me avoid parties because they are very taxing and little fun
*Timbre is pronounced "TAM-BER". Your mistake is understandable, though. I mean, seriously.*
It's a french loan word so other than hacking up a hairball for the ending, we retain the pronunciation to say tahm-ber. It's still UK spelling for wood, but not pronounced that way in the context of sound and music.
Ok, brain cells. I really need you to get it together, here.
“I really hope you get that reference”
I didn’t get the reference
Also: the side notes have returned
Have you guys noticed that whenever you struggle to understand what on is saying after understanding another, the difficult one is so much more quieter whist the easy one is louder? Then when I struggled to understand the beginning of the biking one, the v sauce intro which I thought was quieter than the bee movie one was loud whist the difficult one was too quiet. Now they're all loud lmao
Funnily enough, I read descriptions
People on the autistic spectrum often have a lot of trouble picking out voices from background noise. My brother seriously struggles with it and has almost completely stopped eating at restaurants due to it.
Great video. Psychology is an amazingly interesting subject. How the human brain functions has always been an interest of mine, so I loved this video a lot.
If I have this 'superpower', then for me it simply breaks down at 4 conversations in hearing range (meaning parties are no fun for me). :(
I can somewhat recover by no longer listening but trying to lipread, but I'm not trained for that and it makes following conversations really bad and tends to devolve to the variations of the phrase 'Do I have something stuck between my teeth?'...
I love that you watch Jacksfilms
I could hear and understand them when I was looking at each. But after hearing the first one I could also hear the first one while watching the second one pretty clearly at the same time. The three videos was a bit harder but could hear them all while trying to listen to each while watching them.
dope!
true!
I watched this video but was distracted by the voices of screaming kids.
Since I don’t see anyone mentioning it I felt like I should let u know that timbre is pronounced “tam-burr” (tone quality)
So, you missed a fascinating part of this effect. That is, even if people are saying the same thing, without any noise adjustment, you can still pick out a specific, individual voice*. You can do it by watching the mouth of the person you want to hear. Try it with a music video where you can see the mouths of all of the singers, and try to listen to just one of them by watching their mouth.
* If the voices are too similar, it becomes incredible difficult, if not impossible to differentiate.
In the first view I didn't get it. Will try again. I think the headphones are a must.
Kahneman woot woot!
I got the two easy, I did have to slow down from 2x speed though, but when it got to the three I got the first one but then when watching the second I from some reason picked up the third and had to go back again to the second. Still missed that first sentence.
Early!
Like 146th...
It's not much to be proud of, is it...
Anyway, thanks for another great video, funny and informational at the same time!!!
I am proud of you!
Thanks :)
I could only hear the meme video, I think I have a special set of skills.
OH MY GOD, you talk so fast!!
i read the description ;)
is it a super power if every one has it? like guys, i can take oxegen, burn it in my body and transform it into carbon dioxide, i can also turn any drink into a noxious yellow liquid. im a freakin super hero
i have an auditory processing disorder so i cant filter out sound very easily. if i really really focus i can, but its very tricky.
Repping that Slytherin Flag.
Does the fact that the three voices talking at the viewer were all from the same speaker. Would it be easier to distinguish between them if there was more variety in the tone and pitch?
Oho he's sponsored, respectively makin' cash while educatin'
as foretold in the prophecy, I'm not good at this.
I can kinda tune in after the first few seconds, but even then it's hard. for me, the one on the right intruded much more on the other, but I also couldn't hear it as well when I was trying to, which seems odd.
If timber/timbre is part of the criteria for the brain to sperate voices how can we separate the voices of the same person?
I could hear Bee Movie and Vsauce easily but the first few times I tried to listen to Mountain Biking Bee Movie kept butting in
The one clip about the meme sounded WAY louder
I could not understand the talking of the several voices talking at the same time. It works with one person in a crowded room. Only modern people have this ability.
THYIS
It didn’t work for me idk weather my dyslexia affected it but it was just a confusing and didn’t make sense
I have Central Auditory Processing Disorder so I have a hard time filtering the different voices.
blessed mon
Intresting...
Will keep watching but: this doesn't work as well in videos. Without knowing ahead of time what's being said, it's harder to pick up on it, particularly if you're not familiar with the speaker. So both of your bits blended together a bit too much. This is why it's super important to have a mic close to someone you're interviewing in the middle of a loud room - even if you can see their mouth move, in the flat audio mix their voice will get lost. I get the idea, though, and am gonna watch the rest now!
*Edit: OH you mixed in stereo! No wonder I couldn't distinguish it on my mono phone (monophone phone?). Will have to watch again on desktop!
Yeahhhhh so much better with stereo speakers.
Doesn't work for me at all, not even knowing what you said. No wonder huge crowds are so incredibly stressful for me...
