Shure Mics SM91
The SM91 Microphone is designed specifically for surface-mounted applications. It is a professional- quality permanently-biased condenser microphone with a half-cardioid directional pattern (cardioid in the hemi- sphere above the mounting surface.)
The SM91 takes advantage of the well-known prin- ciple that, at a barrier or boundary, sound pressure doubles compared to its value if the boundary is re- moved. When placed sufficiently near the boundary sur- face, a microphone has effectively 6 dB higher sensiti- vity and approximately 3 dB greater rejection of random background noise.
