Active Noise Cancellation Explained

[@poojashah6183]

Now we know the fact of that secondary microphone on the mobile phones. We owe you sirr👌👌

[@rishabhkrm]

thanks for a detailed video... KEEP UP THE GOOD and QUALITY WORK...👍👍👍

[@aurkom]

Thoroughly enjoy your videos! Would be amazing if you could upload videos explaining working of a transistor too.

[@ALLABOUTELECTRONICS]

Yes, soon I will start the series of videos on the transistor.

[@solidzonewavestation]

Thats is excellent ..um from sri lanka

[@Saxyct]

Very informative, even if it was very hard to follow the content due to the way the speaker talks. all those random pauses between the words make it very tricky to understand what it's being said, we had to rewind the video several times to properly get the content.

Thanks guys . Waiting for this video since i can remember 🙏😊

[@shrutishah7156]

Wow... great information

[@imavileone7360]

Dam, finally, a great explanation!

[@ajithsb1853]

Thank you very much for the detailed explanation. Is there a way to determine the type of noise cancellation technology used in a specific headphone just by looking at it or via visual inspection?? Rather than reading its manual to understand its features. Thanks in advance!

[@ALLABOUTELECTRONICS]

In some headphones, visually you can find the microphone on the outer side. But from that it is difficult to judge, which technology is used for the noise cancellation. Because it can be either feed-forward or hybrid (As, internal microphone is not visible). So, it's better to refer the manual for more details.

ALL ABOUT ELECTRONICS Thank you so much really appreciate your quick response. All the best to your future videos

[@tomc642]

Thank you. Is there also a way of canceling low frequency noise like the high energy bass of a car boom box? To me it seems that is much more of a challenge than high frequency noise.

[@ALLABOUTELECTRONICS]

Using the feedback ANC, the low-frequency noise can be canceled to the certain extent. I have provided more detail about it in the description of the video also. You might find it helpful.

Today i knew the fact about that 2nd small hole in mobile phones. I always thought its for catching signals.. lolxxxxxxxxxxxx

[@peterweber9880]

Minute 2:42 you explain, why the feed-forward technique works for cancelling out high frequency, by saying that ´´the mike is outside the ear, so it picks up the sound early on and has more time to react and generate the anti-noise.´´ Do higher frequencys take longer vor building a anti-noise for them? your explanation about this would clear my mind. thank u

[@ALLABOUTELECTRONICS]

What I mean to say was, at higher frequencies the time available for the noise cancellation reduces. as f = 1/T. So, in feed-forward technique if the sound is picked up early then there is more time to respond and to generate the anti-noise. I hope it will clear your doubt. If you still have any doubt then please let me know here.

Bro which course did u studied bro 😎

[@gy9gy8]

Why feed foward is good at HF and feedback is good at LF?

[@joon7658]

Please.... release more episodes

[@tweakradje]

Does Feedback NC with the microphone near the ear also remove audio "coloring" of the driver? Since it compares with the original input audio it might be the case.
