What is active noise cancellation and how does it work in phones?

    1. Noise cancellation is a mechanism that is used to reduce or neutralize unwanted background noise.
    2. Also known as active noise cancellation, it involves the production of internal sound signals to counter or suppress external noise.
    3. This process is executed through the coordination of microphones that pick up the noise and a chipset that inverts the sound waves to produce opposing sound signals.
    4. far-field noise cancellation involves multiple microphones arranged in either a circular or linear form to reduce the effect of background/surrounding noise.
    5. This makes your video calls properly audible and your recordings clean with no noise.
