A communication device (1) comprising a speaker (2), a microphone (3), a noise detection module (7) adopted to determine an ambient noise level (NL) from a microphone signal received from the microphone (3) and an automatic volume control module (4), which in dependence of a change in noise level adjusts the speaker volume level (SL) to an adjusted level during an adaption time interval (TA). The communication device (1) comprises a motion sensor (5), and the length of the adaption time interval (TA) depends on a motion signal received from the motion sensor (5).
