  abstract={Modern hands-free telecommunication systems have to reduce different acoustic disturbances of the desired
speech signal, amongst them echoes of the far-end speaker due to the acoustic coupling between loudspeaker
and microphone and room reverberation for the nearend listener caused by reflections at the room boundaries.
Common systems for listening-room compensation (LRC) try to design an equalization filter which is the inverse of the room impulse response to achieve spectral flatness of the concatenated overall system of equalizer and room transfer function. Such designs need reliable knowledge of the room impulse response (RIR) which is not available in real systems. Furthermore, it could be shown that shaping approaches which preserve the masking effects of room impulse responses lead to perceptually better results especially in case of estimation errors. In this contribution a system for room impulse response shaping is analyzed depending on the influences of realistic RIR estimates, which are obtained by an acoustic echo canceller (AEC).
