suppression - technical definition

Forceful constraint, prevention, or subduing. In electronics, the elimination or intentional attenuation of an unwanted oscillation, such as a sideband, a carrier, or an echo. In some voice encoding mechanisms, silence suppression senses periods of inactivity in a voice conversation and simply ceases sending data associated with that conversation. See also attenuation, carrier, echo, encode, oscillate, sideband, and silence suppression.
