发明名称 Device and method for influencing an audio signal according to ambient noise amplifies or dampens audio signal frequencies selectively by mixing signals to suit ambient noise.
摘要 In a reproduction chamber (24) a loudspeaker (20) transmits an audio signal (22), converted to an electrical signal (36) by a pick-up device (32) after sampling with ambient noise (28). After pick-up the audio signal passes to a mixer's (42) inverting input (44) and the electrical signal to a mixer's non-inverting input (40). An evaluator (52), connected downstream to the mixer, picks up a mixed signal from the mixer and triggers an equaliser (12).
