Spatial Sensitivity for Listening Room Compensation

Autoren: S. Goetze, M. Kallinger, K.-D. Kammeyer, A. Mertins
Kurzfassung: In many applications for room acoustics the distortions introduced by reverberation due to numerous signal reflections at the room boundaries have to be compensated or reduced. Filters for listening room compensation (LRC) are capable of reducing reverberation effects but are often designed for exactly known source- and microphone locations. Especially for a hands-free teleconferencing setup this assumption may be violated. This contribution demonstrates the influence of spatial errors on listening room compensators. Different LRC designs (including least squares equalizer and room impulse response shortener) are evaluated for different room positions, room reverberation times and filter orders by means of objective measures (D50, variance of equalized system, etc.). Thus, numerous conditions can be analyzed and the equalization results are presented visually and  acoustically.
