How Active Noise Cancellation technology works?

You must have heard the term Active Noise Cancelling Technology (ANC); many of you might be using it on a regular already. But, the majority of customers still feel confused about this term, and this article will give you a basic idea of ANC technology. 

How Active Noise Cancellation technology works?


Noise, as we know, is a mixture of compression and refraction phases of waves. Active Noise cancelling technology creates what is known as antiphase, which is a wave of amplitude similar to that of the outside noise; but with an inverted phase. This antiphase wave, created by the internal circuitry, comes out of the speakers and mixes with the noise.  Now, it should not be difficult for you to imagine that what will happen when the noise from the outside world meets the noise created by the headphone with inverted phase –they will negate or cancel each other. This phenomenon is known as destructive interference. The term “active” means, the noise cancellation technique required energy, and this energy is derived from an inbuilt battery in the headphones.

Now, going back to the other question that how much noise can the ANC reduce, well, the active noise cancellation technique can cut 100% of the unnecessary noise, but, at the present moment, companies, keeping the angle of cost-effectiveness in eyes, make such headphones that are capable of reducing the noise till 80 to 85%.


SRHYTHM is contributed by professional R&D team, product managers, technical support experts, and the customer service team. SRHYTHM focuses on noise cancelling and wireless technologies and is dedicated to providing high-quality headsets. We have been the noise cancelling technology provider to famous headset brands for more than a decade, and most Srhythm’s products can reduce the 85% of noise.


You don’t need to doubt, whether the sound waves created by the headphones will interfere the music you want to listen. Headsets with active noise cancellation are good in distinguishing between the audio sources a user wants to listen and undesirable outside noise that annoys him. It is interesting to know that these headsets can be used even when you don’t want to listen to music; by wearing these headsets, you can have a peaceful sleep in a noisy environment.

Hey, the real feel is in experiencing the ANC first hand and not reading articles about it; so, don’t wait, guys, go get one for yourself (please go to our PRODUCT pages).
