Patent CA-1332626-C (CA)
Inventor: MUNDAY EDWARD
IPC: G10L21/0208
Filed: 1989-01-18
Granted: 1994-10-18
Abstract: ABSTRACT         A  noise reduction system for enhancing noisy speech signals by performing a spectral decomposition on the signal, passing each spectral component through a non-linear stage which progressively attenuates lower intensity spectral components (uncorrelated noise) but passes higher intensity spectral components (correlated speech) relatively unattenuated, and reconstituting the signal.   Frames of noisy signal are transformed into the frequency domain by an FFT device, with windowing. Each transformed frame is then processed to effect a non-linear  transfer  characteristic,  which  is  linear above a soft "knee" region, and rolls off below, and transformed back to a reconstituted time-domain signal with   reduced   noise   by   an   IFFT   device   (with overlapping).   A level control matches the signal to the  characteristic.    In  further  embodiments,  the characteristic may vary between frequency bands,  and may be matched to speech formants by tracking formants using an LSP technique.

Title: Multi-band programmable compression system
Inventor: WALDHAUER FRED D
IPC: H03G9/18

Granted: 1992-01-28
Abstract: IMPROVED MULTI-BAND PROGRAMMABLE COMPRESSION SYSTEM  ABSTRACT OF THE DISCLOSURE A programmable low voltage multi-band compression system suitable for use with hearing aids is described.  Received audio signals are processed by a band split filter which separates the received audio signal into a plurality of frequency bands.  A plurality of compressors coupled to the band split filter compresses each of the respective frequency bands.  The output of the compressor are then summed to generate a composite audio signal.  The compression ratio of each of the compressors is set, in response to a set of control signals, to a preselected independent value.  The average gain of each of the compressors is set to a preselected level independently of the other compressors.  In addition, the compression ratio of each compressor may vary with input signal level. Another set of control signals is employed for setting the gain of the compressor to provide a volume control function.
