Noise Cancellation As Fast As Possible

Noise-cancelling headphones go beyond just blocking sound with physical barriers. What makes them special, and how should you go about choosing a pair?

0:45 you can see YouTube's compression in full effect. The "white noise" background is uncompressable so the quality of everything else drops - in that case it's Linus - so that the footage looks like 240p even though it's supposed to be 4K!

wow the picture at 2:04 is kinda disturbing

3:26 "Although many headphones with active noise control do offer solid sound quality"

Shows beats -_-

linus is one of those youtubers for which I like the video first and then watch it.

[DrSQUIRRELBOY]

Installs those speakers in car => Cant hear that car that is honking at you to go because the fucking light is Green!

[SreenikethanI]

I always love it when it's Linus everywhere :-)

I'm using my Xperia Z3 noise cancellation hear plug headphones and honestly I won't go to anything different, at least some new noise cancelling headphones. Looking forward to see more advanced consumer products with this feature, glad there was a video for this as in the future people will search more often about that :)

at 0:50 of the video there is a high (Somthing) photo in the background and it is preventing all my devices including my phone to render the video. Linus! Take a note and use less high (Something uhh... White noise picture). Not all devices have a great graphics card to render that great of a picture. Oh and like i said i tested it on all my devices which is a total of 5 including my Chromecast for my tv. my internet is also fine since i get a good 70-80Mbps download and standard 10Mbps upload, there is very little traffic going on right now.

Great video but Linus looks a bit yellow at times xD. Please fix this.

Speaking of this, Bose Quiet comfort is the best headphones I ever owned. I have been an avid "gaming" headphone shopper and none of them ever lasted as long as my Bose. I had this Bose for over 3 years now and it's still working and still comfortable to wear. The only downside to this is MIC feature on desktop does not work unless you have a splitter or attach a removable boom MIC like modmic. Otherwise, it was definitely worth $300. From now on, this is the only headphone I'll ever get.

Worth noting that some cars (such as the 2013 or newer Honda Accord) include active noise cancellation (or more accurately, reduction) directly from the factory.

[MrMouse]

Not exactly correct, they have to be in anti-phase to completely cancel out the wave, not just out of phase but good video :)

Welcome from Austria. Nice vid as allways.

[PetarStamenkovic]

Why isn't there software that does this? With good enough microphone(s) and speakers you could noise isolate your own room. With our own high end PC/mic/speakers we normally have anyway. All that's missing is software that would allow this. So, wheres this software?

Teaching superposition to my year 13. What a coincidence! Thanks LMG.

Is it me or does linus have yellow palms and other parts?

[CrafterSandstone]

I think it makes it simpler to understand the principle of how noise cancellation works through his explanation with transverse waves. The logic would still transfer over to longitudinal waves (the kind of wave which sound travels in).

[Uejji]

Sound waves move in compression waves (forward-backward), not transverse waves (up-down) like light or water waves. Other than that the properties are similar enough for the analogy to work.

Interesting fact: Car companies like Audi (Others probably too, but i don't know about them) already use active noise cancellation. Some engines can shut down some of their cylinders to reduce mileage which leads to a "out of roundness" and therefor unpleasant noises. These then get cancelled out by sending antiphase-waves over the car's sound system. So it is the same principle like in your headphones only that the calculation of the right frequencies and phases gets far more complicated since the interior of a car is a three dimensional space.

I have a set of Bose noise cancelling headphones. I used to wear them to bed because my roommate was a snorer. I absolutely love them
