Abstract:
1. In a telecommunications system having voice communications subject to noise, a distributed noise suppression system for suppressing the noise for a given one of the voice communications, said noise suppression system comprising: a first noise suppressor, within a first device, giving a first amount of noise suppression level for suppressing noise in the first device prior to transmission of the noise-suppressed signal to a destination device prior to an encoding process, wherein the first noise suppressor is adapted to suppress acoustic background noise, said first noise suppressor including: a second noise suppressor, within the destination device, giving a second amount of noise suppression level for further suppressing the noise-suppressed signal received from the first device, and decoded in a decoding process, wherein the second noise suppressor is adapted to suppress noise due to encoding and decoding distortion and transmission noise, said second noise suppressor including means for adjusting the level of noise suppression in inverse relation to a bit rate utilized in the encoding and decoding processes; whereby the noise associated with the given voice communication is reduced by an overall amount of noise suppression level.
