SOUND ZONE ARRANGEMENT WITH ZONEWISE SPEECH SUPPRESSION

摘要

A system and method for arranging sound zones in a room including a listener's position and a speaker's position with a multiplicity of loudspeakers disposed in the room and a multiplicity of microphones disposed in the room. The method includes establishing, in connection with the multiplicity of loudspeakers, a first sound zone around the listener's position and a second sound zone around the speaker's position, and determining, in connection with the multiplicity of microphones, parameters of sound conditions present in the first sound zone. The method further includes generating in the first sound zone, in connection with the multiplicity of loudspeakers, and based on the determined sound conditions in the first sound zone, speech masking sound that is configured to reduce common speech intelligibility in the second sound zone.

1. A sound zone arrangement comprising:
a multiplicity of loudspeakers disposed in a room that includes a listener's position and a speaker's position; at least one microphone disposed in the room; a signal processing module connected to the multiplicity of loudspeakers and the at least one microphone; the signal processing module configured to: establish, in connection with the multiplicity of loudspeakers, a first sound zone around the listener's position and a second sound zone around the speaker's position; determine, in connection with the at least one microphone, parameters of sound conditions present in the first sound zone; and generate in the first sound zone, in connection with the multiplicity of loudspeakers, and based on the determined sound conditions in the first sound zone, speech masking sound that is configured to reduce common speech intelligibility in the first sound zone.
