Proper room acoustics for audio teleconferencing and video teleconferencing facilities has been, at best, a matter of guesswork. In this paper, room acoustic treatments are varied in material and location within a typical conference room and the results studied using binaural analysis techniques. The relationship between room acoustics, speech intelligibility, speech interference, and mechanical noise levels in regard to teleconferencing systems will be explored in a quantitative manner, including the effects of ``echo cancelling'' technology.
