Abstract
An aspect of the present invention relates to an active noise cancelling or an active noise gating system that applies an algorithm for reducing ambient noise. The active noise cancelling system may be used to cancel undesired background noise but for an audio signal which is desired to be heard by the user. The present invention acts as a noise gate, wherein the algorithm(s) actively senses ambient noise levels and the algorithm stored in system memory instructs the device to mute a microphone at or above certain preset noise levels. The preset levels in which the system may mute background noise may be applied by the user using a slide bar that the user may manually adjust to apply more or less noise gating
