How Do Noise Canceling Headphones Work?

The engineering inside noise-canceling headphones is rather intricate. Let's see how.
Take a look at their PCB Assembly, for an inexpensive population of the components on your PCBs.

Noise is all around us, so how have engineers designed headphones that eliminate it? Well in this video we explore the physics of active noise-canceling headphones, and how noise can be removed from the environment using technology.

I know how difficult it is to model all these components. You have designed them so accurately. Hats off to you for these contents.

This guy deserves more keep sharing guys let’s help him reach 1M by this year

[JaredOwen]

Great job Teddy! Keep up the good work

[evqwoie]

These are the best videos on the internet for high quality engineering explanations. Thank you for educating the world one subscriber at a time.

people don't appreciate this free high quality content 😔

When I studied this in university, I loved how simple it is in concept to cancel soundwaves with their opposites, but I see that even as simple as it looks, it's still challenging to make it work properly in a real life situation. Great video!

I’m wearing noise canceling headphones watching this! Really interesting to know how they work.

I work in a sawmill and just got a pair of Beats Studio earbuds. Life changer, I haven’t had a headache since than. I literally can’t hear the buzz of the saw’s running.

If it was a gaming or comedy video
It would be in trending
But it is educational video ❤️

How could such a creative person be so underrated ?

[PauloNideck]

amazing video, top notch quality content.

[mrflip-flop]

This feels so relaxing to watch and so high quality as well.

[badhrihari]

I need noise cancelling headphones to binge watch your awesome content

[truthseeker]

i feel so refreshed learning something interesting. too many youtubers trying to sell us tech they dont understand how it works, here i learnt something and i'm happy.

[MvsG]

I loved the 3D graphs and demonstration you've made, also love how you used an earphone that doesnt cancel audio passively or activelively lmao

[heyitsvos]

This relaxing voice and speech characteristic makes this so easy to soak in, even if you're just passively listening. Cheers

[trentoncrabtree]

This video did such a good job at explaining! Thank you for the high quality content! 😃

[LeoFernandez-vppf]

You know what? Thanks a lot. This is lowkey underrated and I learned exactly what I wanted

[olqdnxy]

I was waiting for this video, now is here.

Congrats for the great content

I would absolutely love it if you would do a video on how you make your high detailed models! I know you simply explained the process here and that it is likely some form of photogrammetry among other things but seeing the process would be super cool as your models are always so well done and look incredible.
