  abstract={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.
