C 316

• High Sound Pressure Calibration Coupler

• The C 316 high sound pressure calibration coupler is a sound source specifically designed for ultra-high sound pressure measurements. It performs measurements by generating a pressure sound field inside the coupler and is typically used for testing the sound pressure limit of microphones.

  The C 316 achieves a maximum measurement sound pressure level exceeding 164 dB (at 500 Hz) with distortion of less than 1%, meeting the requirements for maximum sound pressure measurement of high sound pressure microphones.
