Effective Design of Audio/Video Conference Rooms

摘要

Economic pressures, changing business models, and environmental concerns are increasing the use of video conferencing, telepresence, and distance-learning technologies in academic and corporate settings. A successful return on investment for these systems rests on their adoption among prospective users. Acceptance is maximized when the conferencing system provides a realistic virtual presence between users. Acoustics and speech intelligibility are key components of this effect. This article presents an overview of different conferencing technologies, their acoustical requirements, and built-in acoustical controls such as echo-cancellation, noise reduction, and voice lift.
