The TANDBERG AudioScience microphone is a ceiling microphone designed specifically for use in Videoteleconferencing and Distance Learning environments. It consists of a Crown PZMR microphone attached to a boundary specifically shaped to optimize the Frequency response, Polar response, and reach of the microphone assembly. Also, the combination of those parameters enhances the performance of some echo cancelers, and results in some "natural" automatic gain control functions.
