GRAS 51AB Phase Calibrator according to IEC 61043
The Sound-intensity Calibrator 51AB is a coupler for phase and level calibrations of sound-intensity microphone pairs. It can be used for residual intensity testing, sound-intensity level calibration and particle velocity calibration as specified in IEC standard 1043 Electroacoustics-Instruments for..
