A Psychoacoustic Noise Reduction Approach for Stereo Hands-Free Systems

Authors: S. Goetze, V. Mildner, K.-D. Kammeyer
Abstract: One demand for comfortable high quality hands-free video conferencing systems is the transmission of a spatial acoustical impression. Therefore a major task is the transmission of stereo speech signals from a noisy environment. The suppression of the noise components must not corrupt the stereo effect. In this context different single channel, multi-channel and hybrid speech enhancement systems will be evaluated in this contribution. The problem of musical noise in Post-Filter-algorithms is addressed. Therefore a psychoacoustic masking threshold for the noise reduction algorithms is considered.
