What Is Noise Cancellation In Earphones
As the name suggests noise cancellation refers to cancellation or termination of the noise that your microphone catches.
Noise cancellation is not going to benefit you directly but it makes your voice clear and makes others hear you properly.
Earphones that supports noise cancellation feature are built in such a way that they only catch your voice and ignore the unwanted background noise.
Noise cancellation can be achieved in different ways like by using 2 mics in one earphone, one is present near your mouth that will catch your voice only and the other is preset far from your moth it will catch noise only and then the smart feature subtracts the noise audio from your voice.

The results produced are awesome and it filters out all the irregular, unwanted high-frequency sound and provides crystal clear voice.
Active Noise Cancellation
Active noise cancellation is done by using advanced technology, it is performed by analyzing the sound pattern of the noise and then it generates the same anti-noise signal to cancel it out.
The final results that come out are totally amazing without any kind of noise and disturbance.
This type of noise cancellation is ideal for those noises which produce a uniform pattern, for example, a ceiling fan running in the background.
