A noise gate or simply gate is an electronic device or software that is used to control the volume of an audio signal. Comparable to a limiter , which attenuates signals above a threshold, such as loud attacks from the start of musical notes, noise gates attenuate signals that register below the threshold. [ 1 ]
Noise reduction is the process of removing noise from a signal. Noise reduction techniques exist for audio and images. Noise reduction algorithms may distort the signal to some degree. Noise rejection is the ability of a circuit to isolate an undesired signal component from the desired signal component, as with common-mode rejection ratio.

This audio allows users to have face-to-face conversations in high-noise environments up to 95 dB without removing their hearing protection. It also provides 360-degree situational awareness (Directional - 3D sound ) that allows the wearer to determine which direction the voice or other audio (Noise) is coming from.
Sound masking is the inclusion of generated sound (commonly, though inaccurately, referred to as "white noise" or "pink noise") into an environment to mask unwanted sound. It relies on auditory masking. Sound masking is not a form of active noise control (noise cancellation technique); however, it can reduce or eliminate the perception of sound ...
Microsoft is doing something about annoying background sounds by introducing noise suppression to party chat in the latest Xbox update.
Adaptive noise cancelling is a signal processing technique that is highly effective in suppressing additive interference or noise corrupting a received target signal at the main or primary sensor in certain common situations where the interference is known and is accessible but unavoidable and where the target signal and the interference are unrelated, that is, uncorrelated [1] [2] [3].
