Abstract

A multichannel acoustic system (MAS) comprises an arrangement of microphones and loudspeakers and a multichannel acoustic processor (MAP) to together enhance conversational speech between two or more persons in a shared acoustic space such as an automobile. The enhancements are achieved by receiving sound signals substantially originating from relatively near sound sources; filtering the sound signals to cancel at least one echo signal detected for at least one microphone from among the plurality of microphones; filtering the sound signals received by the plurality of microphones to cancel at least one feedback signal detected for at least one microphone from among the plurality of microphones; and reproducing the filtered sound signals for each microphone from among the plurality of microphones on a subset of loudspeakers corresponding that are relatively far from the source microphone.

Description

[0001] Cross References to Related Applications [0002] This application claims priority to commonly owned U.S. Provisional Patent Application No. 62 / 091,367, filed December 12, 2014, and U.S. Nonprovisional Patent Application No. 14 / 808,870, filed July 24, 2015, above The content of the application is expressly incorporated herein by reference in its entirety. Background technique [0003] Conversation between two people may be difficult in a shared acoustic space where other people are speaking, other sources of noise (speech and non-speech), and / or other physical limitations of the environment make speech difficult accomplish. For example, in the context of a moving car, it may be difficult for a person in the front passenger seat to easily and clearly converse with a person in the third row passenger seat because other people in the vehicle (which may be closer) Voice is occurring between the front seat occupant or between the front seat occupant and the third row seat...
