Abstract

Dynamic range compression is widely used in digital hearing AIDS, but performs poorly in noisy conditions with multiple sources. We propose a system that combines source separation, compression, and beamforming to compress each source independently. We derive an expression for a time-varying weighted multichannel Wiener filter that performs both beamforming and compression. Experiments using recorded speech and behind-The-ear hearing aid impulse responses suggest that the combined system provides more accurate dynamic range compression than a conventional compressor in the presence of competing speech and background noise.
