Abstract
A communications headset has a microphone boom that is moveable through various distances from the user's mouth, in which movement of the boom operates electrical, mechanical or acoustic mechanisms to adjust the transmit sensitivity of the headset such that the ratio of the amplitude of the output signal of the headset to the amplitude of the sound pressure at the vicinity of the user's mouth is maintained relatively constant, independently of the position of the microphone boom.
