Abstract

An audio processing method and apparatus are described for discouraging vocalisation or the production of complex sounds. The method comprises the steps, performed in a repeating cycle, of: receiving (74) ambient audio; detecting (74) when the received ambient audio is loud; and broadcasting (84, 92) a burst of output audio so as to mix with the ambient audio, the burst of output audio being timed in dependence upon the detection of loud ambient audio.
