Active noise control ( ANC ), also known as noise cancellation ( NC ), or active noise reduction ( ANR ), is a method for reducing unwanted sound by the addition of a second sound specifically designed to cancel the first. The concept was first developed in the late 1930s; later developmental work that began in the 1950s eventually resulted in ...
Echo cancellation and suppression can work in conjunction to achieve acceptable performance. Quantifying echo[edit] Echo is measured as echo return loss(ERL). This is the ratio, expressed in decibels, of the original signal and its echo.[8] High values mean the echo is very weak, while low values mean the echo is very strong.

The internal electronic circuitry of an active noise-canceling mic attempts to subtract noise signal from the primary microphone. The circuit may employ passive or active noise canceling techniques to filter out the noise, producing an output signal that has a lower noise floor and a higher signal-to-noise ratio. Applications.
