Designed for phase match, amplitude match and pressure-residual intensity index measurement of sound intensity microphone pairs.
Type 9721-B
A microphone calibration system for phase match, amplitude match and pressure-residual intensity index measurement of sound intensity microphone pairs. The system, Type 9721-B, applies specially designed comparison couplers for the measurements.
Type 9721-B is a specially designed system for determining the phase and amplitude match of sound intensity microphone pairs described in IEC 61043. This system also calculates the pressure-residual intensity index of the calibrated microphone pair. The system has specially designed comparison couplers for ½-inch and ¼-inch microphones. The couplers, adaptors and other system hardware are designed to fit Brüel & Kjær microphones, but can also be used with other makes of microphone with similar dimensions and electrical terminals.
