Nor1294 Phase verification coupler
Based on the innovative method invented by Norsonic to correct the phase response of a sound intensity analyser, the Nor150 offers the following outstanding unique features for sound intensity measurements; Measurement of the complete frequency response with the 12mm spacer with significantly higher dynamics than required in current ISO standards.
Use the phase verification coupler Nor1294 to perform a phase correction procedure to minimize and verify the residual intensity when the intensity probe is exposed to a completely reactive sound field. For use with the Nor1290 sound intensity probe or other 1/2″ sound intensity microphone pairs.
