Abstract
The invention relates to processing signal for improving a sound pick-up in telephone and/or videophone units. The inventive method consists in comparing () a signal transmitted by a unit microphone (Mic) with a threshold low value (THR_LOW) and in amplifying () said microphone-transmitted signal when it is less than the threshold low value. However, said steps depend on the test () carried out on a signal used for feeding the loud speaker (HP), in particular consisting in controlling said last signal (crete_HP) of a background noise order (BDF) in such a way that the background noise is not amplified by an acoustical coupling between the microphone (Mic) and the loud speaker (HP).
