An adaptive volume controlled radiotelephone system includes a microphone, a loudspeaker, a transceiver, and an adaptive volume control. The microphone generates an output electrical audio signal in response to sound, and the loudspeaker produces sound in response to an input electrical audio signal. The transceiver is responsive to the microphone and transmits radiotelephone communications to a remote party and receives radiotelephone communications from the remote party to generate the input electrical audio signal. The adaptive volume control is responsive to the output electrical audio signal and selects an amplitude of the sound produced by the loudspeaker so that the amplitude of the sound produced by the loudspeaker increases as the amplitude of the sound received at the microphone increases and decreases as the amplitude of the sound received at the microphone decreases.
