Acoustic calibrator / for sound level meters

The Intensity Coupler Type 51AB is a coupler for calibrating the phase response of microphone pairs used for measuring sound intensity, e.g. the Type 40AI and Type 40BI.

It includes a calibrated acoustic resitance to enable the computation of particle velocity and intensity levels.

The Type 51AB complies with the standards of IEC 1043.

Specifications
