Abstract  Abstract

(57) Summary A noise suppression system (109) implemented in a communication system (700) makes improved update decisions in the case of a sudden increase in background noise level. The noise suppression system (109) performs updates, inter alia, by continuously monitoring spectral energy deviations and forcing updates based on predetermined threshold conditions. The spectral energy deviation is determined utilizing elements having past values of the exponentially weighted power spectral components. Exponential weighting is a function of the current input energy, which means that the higher the input signal energy, the longer the exponential window. Conversely, the lower the signal energy, the shorter the exponential window. The noise suppression system (109) also prohibits forced updating during a continuous non-steady input signal (such as music-on-hold).
