ABSTRACT:
A sound environment control apparatus which allows a user, by operating a remote control unit, to selectively suppress any or all of multiple noises in his or her environment, or selectively listen to any of these while suppressing all other sound. One or more "primary" sound detectors are located in the user's sound domain to acquire all sounds that the user desires to hear as well as interfering sounds, and one or more "reference" sound detectors are placed at each interfering sound source that the user may wish to be able to control. Signals from the sound detectors are sent to a central processing unit/multiple sound controller where the interfering sounds are adaptively cancelled from the total audio provided by each primary sound detector or, when enhancement of a particular sound, rather than suppression, is desired, the audio from a reference sound detector is amplified and added to the total sound from the primary sound detector or used to replace the total sound from the primary sound detector. The resultant processed sound is then provided to the user.
