- Noise-cancelling headphones have become pretty popular over the last decade or so - here's how they work. The concept actually dates back to 1978 when Dr. Amar Bose, an MIT professor, created the idea on a flight he was on.

Ok Edgelord
Just follow the voice they will stop eventually when you stop breathing

Ideas like your get people killed. 😬

They only block out certain sounds unfortunately
Why not use noise cancelling earphones with noise cancelling headphones?
*I see that as an absolute win*
Basically they make you deaf until you realize that you're jaywalking on a highway
I used it for gaming, they can just go to my room if need something
Some people ain't stupid enough to used headphone outside instead of earphone
Razeluxe 13 uhhh use alien ware headphones better and more bass
they make you deaf not blind...
CptKirk FPV also, they make you deaf. They do not erase one's common sense.
i guess they make u blind too?
Nice ad, Bose.
😂😂😂
Nation wide actually
Actually they're the one to bring this concept and ANC headphones 🤷
@@arjuna8785 but not the only one that makes ANC headphones
@@GAGRA0 I didn't say that bro. Just passing some information 🤗
Headphones be like : “No u”
Basically
Technically true
Imagine using them on the plane and suddenly the plane starts dropping cause u used bluetooth
So underrated coment
Lmao 🤣
Noise cancelling headphones really motivated me to keep working out. It was hard for me because I used to feel a lot of anxiety from being surrounded by that many people and all the noise they make, but now I feel like I'm just there by myself.
Interesting. I'll try to remember that. What headphones did you get?
@@babbisp1 I got some Huawei earbuds, didn’t have much money, but they work great. Freebuds 4i I think they’re called.
Totally agree, they basic cancel everything so if you play music it’s line “already, this is my zone, time to zone in.”
This comment is an ad
What about your eyes?
You explained 'active' noise-cancelling headphones and left out 'passive' noise-cancelling headphones. Now 18k+ people will think all noise-cancelling headphones have this tech.
The term “passive noise cancelling” seems to me to have fallen out of favor and been replaced by “noise isolation”. The packaging on headphones sold today reflects this change, at least in the US
@@Jaur-jaur 'Noise isolation' (as I understand it) refers to earbuds that fit in-ear, like a plug or over-ear cover. They isolate your ear from sound (except of course the sounds from their speakers). A cheap to produce approach and no real tech, just a physical sound barrier in or around your ear. Passive noise-cancelling is where white-noise is injected into the headphones to mask external sounds. I have some cheaper Sony's that do this and I have had some success in aeroplanes with these. Basically a low hissing tone. Active noise cancelling, is well, as per the video, which as we see has left out two of the three types of noise 'cancelling' headphones. (they could update the description to specify what they are really discussing)
djt2412 Active noise cancelling headphones do produce a bit of white noise, though it’s quite low in volume. Older models produce more. Are you sure they’re not actively cancelling?
@@Jaur-jaur Not according to the video above. My active headphones produce no sound unless its music or phone call. It's nice and quiet inside. Passive, they produce white noise to try and mask the sounds. My passive's were much better than airline standard headphones, but the actives, a whole other level of noise suppression.
@@Jaur-jaur My old ones are Sony MDR-NC8's bought in 2013 for ~$50. They make a hissing sound of which Sony says "After you turn on the power of the headphones, you may hear a slight hiss. This is the operating sound of the noise cancelling function, not a malfunction. The noise canceling function works for noise in the low frequency band primarily." They were pretty good for aeroplane use. But my current Parrot Zik 3's are dead silent, even weirdly silent and seem to have no limitation on frequency band (to my untrained ear). On my last long haul flight, it was like the whole cabin just got turned off. We may be splitting hairs on terminology so I'm happy to be wrong (or right ;-)).
I have noise canceling headphones from bose and i love them! when i was little and newly diagnosed with autism i had many meltdowns but ever since i got the headphones they’ve made my life easier
Same. I just got them yesterday
4:09 excuse me let me just put my noise canceling headphones on top of my hair
Its on her hair and not on the ears
True
LOL
4:09 Original Af
These things terrify me solely due to the fact that I cannot stand not being able to hear my surroundings.
You're not supposed to use them on the street lol
Using them in public is scetchy, so many unpredictable things happen
Turn the noise cancelling off
That's a blessing for me, I'm tired of hearing the noise around me.
Fuzion Insanity ok weird
You forgot to tell about the "Cabin Pressure" it creates when Cancelling the noise! That pressure could be Uncomfortable for some people as many of us have Sensitive ears!
Nothing is perfect yet
It'll improve in the future
That's why the Sony wh1000mx3 adjust noise cancelling from the app depending on altitude
Sony uses technology that compensates the barometric pressure change.
thank you! im not the only one
Yes, it's very uncomfortable.
I just got sony xm4 and tried noise canncelling for the first time, omg it is amazing. It's like I stepped into a peacebubble. I can't describe what it feels like, its like heaven. Just having the noise cancelling turn on, no music or anything.
As someone who gets really, really bothered by background sounds (especially the bloody fridge in my room!), noise cancelling headphones are an absolute godsend.
Or why is the bloody fridge is in your room 😂
Get a better fridge. A normal fridge shouldn't make any noise
Will it cancel noise from someone walking on a hardwood floor, or impact noise?
I have tinnitus all my life, never knew what silence feels like
I got it when I was 14
Oh wait i thought everyone had them lol
Got it when I was 15
How to get rid frm tinnitus
Its so annoying
I bought an ANC in-ear earpiece and it works wonders, was wondering how it works and now I'm here. Thank you Bose.
Just bought some noise canceling headphones for the first time and when I turned it on in my room at night I was shocked at how silent my room became because I always keep a loud fan blowing and I thought it became unplugged I was amazed.
What’s brilliant about this invention is that the headphones listen for noise in order to deconstruct it. It actually filters out all the unwanted noise and in doing so makes it easier for the wearer to pinpoint specific sounds and where they’re coming from. Sure you’ve all been in a crowded room and you wonder where that comment came from, well these things cancel out the interference between you and that voice so that you know exactly where it came from. It’s a perfect eavesdropping device.😈
Not how they work
Lemme go deaf real quick.
Lmao
Bought AirPod pros today. And this is exactly what I said. Lmao
@@payitforwardpower9910 same
@@payitforwardpower9910 bought some Sony wh-1000xm4’s recently
@@OfficialXVideos ill be doing the same
How do noise cancelling headphones compensate for any latency between picking up external noises and inverting the phase? For it to work the latency would have to be equivalent to the time it takes from sound waves to travel from where it picks up external noise to the speakers, which is variable depending on air pressure and humidity. Are atmospheric conditions assumed?
As an IT professional I should’ve known this already but didn’t and since I’ve been working with a headset frequently during Covid19 this was an interesting thing to learn!
It has nothing to do with your " IT PROFESSIONALISM" , its more inclined towards sound enginnering . Noise cancellation isn't a feature of IT , rather its more engineering related .
@@shobhitsadwal756 LOL precisely. As far as I know, acoustics has nothing to do with IT. Noise cancellation technology is a product of electronic engineering.
Thanks! I'm affine to technics and hungry to hear, see, read all I can about it. This video made it clear at an easy way, great! Be blessed and please never stop doing this. :)
I got a JBL Tune 660NC a few days ago. I find this technology interesting. It's like a faint white noise or rather a sound one would hear at an open place with currents of air, not really a wind.
having done physics they explained "constructive" and "destructive interference" wrong. LOL when the waves combine it's just called interference. constructive is just the points where they add and destructive it where they cancel each other out. So "goodbye" and "hello" both constructiely and destructively interfered to give rise to the combined wave of both. Then noise cancelling then aims to destructively interfere with that total wave, but not perfectly since if it was perfect then it would actually be silent. sadly we aren't at that point in ANC
See that's probably what they wouldve said if this were a physics class but this is a four minute youtube video
It still gets the point across so their is no real point in being so meticulous about it.
Wasn’t expecting this mind blowing experience of attaining new knowledge
@jamie 999 bro please tell me which one should I buy do they really work neighbors are irritating idiots with their tv noises I need to concentrate on studies please help me
@@Yeesss1356 i have a pair of sony wh-1000xm3's and they are really good. they don't drown out all of the noise by themselves (you can still hear people talking or other sounds) but when you play some music or white noise or something similar it is nearly impossible to hear anything.
I love how I can just touch a button on my beats pro and all the noise just disappears this amazes me every time it never gets old !
I would recommend switching from beats to either Bose or Sony, beats are mostly fashion and Sony headphones are incredible, along with bose
@@OfficialXVideos well the new Beats Fit Pro with ANC are phenomenal..
I also own the Sony ANC buds.. There ANC is next world...
@@Thegoldenchild415 they aren’t bad, I just recommend other brands.
@@OfficialXVideos are you talking about the Beats Fit Pro? Your comment is from 5 months ago, and these just came out on the 3rd of November.
@@Thegoldenchild415 beats in general, though they are getting better I still strongly believe other brands are better
What a great explanation!
Thank you.
I use anker's soundcore q20 and used on planes 4 times this summer. Its pretty good for what it's worth (50 euros). Definitely clears the deep noises. But doesn't kill the all noise. Still very good
Anker is amazing
Lmao using these rn i love em
I own the Sony WH1000XM3. Honestly, if you’re looking for the most well-rounded, I’d choose the sonys. This video was practically an ad for bose, not a single mention of sony, except for images. The bose are mostly for comfort, but also are good at noise cancellation. However, the sony’s can be uncomfortable for others because your ears will most likely touch the drivers. The sonys are definitely the clear winner over noise cancellation. Personally, the touching doesn’t annoy me, but you may beg the differ. Hopefully I make an impact on your choice and make your choice easier and less stressful.
:)
I wore that thing and I thought the world stopped bc noone is talking :P
Really enjoying My xm4’s!
Agreed! The XM4s are amazing. I wear them for significant chunks of the day. Everything is so much calmer and nicer with them.
I will buy an XM5 this week.
@@aubreybondocAre you satisfied with them?
Around the same time this video was uploaded, I ended up getting a pair of the Bose QC35ii in Silver. I still continue to use it more than 1 year later as of March 2021.
Amazing Learning the purpose and what's behind the working of Noise Cancellation Headphones!
What a great innovation and way they are describing it is awesome too✌
These work like magic ✨
Is there any delay that makes this technology inconsistent?
Because when the headphones listen and create a wave, it's already too late, the crowd sound has already changed. Some of the waves gonna be the same if the overall crowd sound is the same but most of them gonna change even just one millisecond after, with different frequencies so this seems impossible to create a good noise cancellation because of the delay. Am I missing something?
This concept is GENIUS. I cant believe someone came up with this
I learned about destructive interference in science and then realized that’s how noise cancellation works and I’m proud of myself for getting it right😎
I didn't get how the waves get eliminate
Pride is the worst sin
@@mary9999fgjj Basically, the headphones generate a opposite wave length that cancels out the original. Like 1 plus -1 equals 0 or “silence”.
The reason talking and other inconsistent noises are sometimes hard for the headphones to cancel out is because the headphones are constantly picking out new wavelengths that it has to attempt cancel out.
i prefer getting the loudest speakers and blasting them so loud that everyone else leaves from getting headaches whilst im chilling being half deaf from them talking so loud
I knew it! Consistent environment. Thankyou so much for confirming.
What an insightful and educational video. Thanks for the knowledge. 👍
Crazy. I am standing on a main street in berlin having my bose nc 700 on. I removed the headphones just to hear that my actual envorinment sounded like a starting jet compared to what i thought it was.
I'm seeing comments saying these are so good on planes and trains but my anxiety is literally saying "But what if there's some important information on the speakerphone about a delay or an issue and I won't be able to hear it because of noise cancellation???"
Just ask the person beside you and ask them to nudge you if something like that happens
can we wear noise cancelling headphone while working with fibregation, metal drilling or metal grinding ?
Very good video!
Concept explain very well.
So THIS is the guy I need to thank for helping me survive the past 5 and a half years of my relationship.
Actually you should specify you are explaining active noise cancelling. Could have included a sentence about passive noise cancelling.
Finally someone explained it...have been searching for it.
It's pretty damn incredible that the headphones can determine the soundwaves that it precisely needs to cancel out and then create the canceling waves in real-time .... amazing this isn't just science fiction.

I have these headphonesfor a year now. It works, mainly used for playing overwatch with a v moda boom pro as my mic. Its good but expensive.
Nice Ad. Quite interesting and informative.
So do they lower the decibels that contact your ear or are they doubling the decibels when they neutralize the sound with another sound wave?
I have a pair of the Bose Quiet Comfort 2 earbuds, and wow, the noise cancelation on those is absolutely amazing. I recently was on a flight, and while is still could hear the place engines, it wasn't nearly as loud. I ended up just using them to dampen the sound while I read a book rather than listen to anything.
I actually can't believe I discovered how it worked before watching anything about this
It's very intuitive tbh
this is a very good and thorough explanation thank you
Wow...i feel so informed right now....so simple....thanks
I use AirPods with noise canceling and they definitely work way better on constant sounds like fans. Speech not as well but they become quieter.
There's a song with the same kind of tune as that in the start. I can't remember it. Can someone help me?
Ash ` I’m have the exact same issue!! I need to know! Did you ever find it?
Ash ` bedroom by litany?
Listening to the song right now, and it sounds different from the background track from the video.
I have a question actually. Does this noise cancelling headphones work while some song is played on the headphone and you won't be hearing anything except for that song or it happens like that nothing is being played on the headphones and even then you won't be hearing anything while wearing it, like it can help you studying or when you want silence in noisy places ???????
Very informative. Thankyouu.
They're great, the ones I own though (Bose) don't really go with my style😅 like I'll wear a hoodie, looking my age, these things look completely out of place😂😂😂
It somehow gives me headaches to listen with those
Nicely made video
use separate drivers to cancel the sound not the main music drivers. that would also fix the distortion problem at louder volumes.
they basically take the soundwaves around you and reverse the frequency to cancel out any incoming noise when you wear the headphones
Amplitudes*
@@axa993 That is a stretch
That’s literally what the video says.
I was about to buy the bose and saw alot of videos and now this?
Hi there when use ANC mode to listen a song is it affect(ANC) To quality of the sound is it compress highs and laws just because of this does reduce the quality of the sound?
No, the Sony xm4s are perfect example of best noise canceling. Sony's DSEE Extreme allows your audio to remain high quality or same with LDAC support to reduce latency that comes with Bluetooth headphones/earbuds.
Watching this on noise-cancelling headphones
I got them yesterday and I was tripped out on how it works
Interestingly bose invested heavily on vehicle smooth suspension technology using same noise cancellation technique .
Well I thought sound waves were longitudinal and that wire was in the shape of a transverse.
True, but this sinusoidal wave is still an accurate way to describe it.
Will they block out the vibrations of heavy base soundbar. Does that even makes sense? 🧐
Need these!
I used to use airpods and they definitely haven’t worked well since my ears started hurting, my surroundings can still hear me and I simply turned the music even louder bc there was too much noise outside.
I got the JBL Live 650 and they’re amazing! Plus they keep my ears warm in winter haha I actually just wanted to get some headphones instead of ear phones and these were on sale and were nc too~ I’m so happy 🥰✨
where did you use your airpods? in a firing range?
Seriously lol, airpod pros were considered on of the best choices for noise canceling last time i looked it up. I certainly have no issues or complaints with the effectiveness of my own air pods noise canceling. Its crazy how well such a tiny package can do it.@tyukikiquinchi7367
This makes so much sense it’s like math
Multiplication cancels division
I get it now
Easier to think of it as adding the negative of a number to itself, you get zero
I was absolutely blown away by my BOSE 700
So how can i in Audacity, create two tracks of opposite wave that cancelling each other?
I have two different headsets. The Bose QC35 and Sony MX4. Ok so the Sony MX4 have better sound and better noise cancelling. But the Bose feel more comfortable to wear for long periods of time (5+ hours) but the downside is the weaker sound in music and weaker noise cancelling. : / I wish both headsets didn't have downsides.
Bomb:is planted
Me:is with these headphones and can’t hear the terrified people near the bomb
Is noise canceling of the Sennheiser HD 450BT good?
Nicely explained
Listening on my XM3s👑
0:27 well I expected this concept to date back as early as 1950s because in some tom and jerry episodes which were made in 1950s ,you could at times see tom put this headphones over spikes ears to prevent him from hearing the noise he was making
Lol I remember that episode but I thought they were earmuffs
@@pranav7551 probably were
How do they process it so fast? and send the sound wave back?
Great explanation
I have the exact same headphones on your video! The Bose quiet comfort. Great vid btw, very informative
Loo
I can save you a whole video.
Reverse sine waves. They listen to the ambient sounds and make a 180° sine wave to drown the outside
That was very interesting, thank you. 👍
Can I use the recorded sound of a plane or a train and allow them to mix with the other noises from the environment? Would that block all the noises if I used it that way?
Nope.
Bose's noise cancellation feature in their wireless earbuds are amazing but it has poor speaker quality. You have to speak a lot louder during calls.
3:31 hearing a car honk may makes the difference between life and death... So is that a bad thing?
Dom Nic Nobody wears these while driving lmao
Have you heard of eyes
How does the microphone makes the same opposite soundwaves?
Very informative video!
I'd buy a pair if they could cancel out the ringing in my ears😏
Bruh same
GOD Bless the inventors of this technology 😌
Almost drown out everything is an overstatement which ends up having people being disappointed
What's the song at the beginning of the video?
Who else is watching this video with their noise cancelling headphones
You girls actually put headphone over the hair and tell
"Poor quality and no noise cancellation"
Right like what goes through their mind
True... they should put their hair back first then wear the headphones
could you people be more sexist? there are people who wear even wear right over their ears and not over their hair
Darshana Balakrishnan that’s not sexist...
I know, I’m a girl and I get so mad when other girls do that
Picture perfect explanation
How are they different from earplugs? Are they making same effect?
