- 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.
- The procedure for this correction of the phase response is so conveniently integrated in the Nor150 that it can be performed very easily and quickly before each measurement!
- For use with the Nor1290 Sound Intensity Probe.
Dynamics with single spacer
- The diagram shows that thanks to the new algorithm with a 12 mm spacer, this phase calibrator makes the Nor150 Sound Intensity measurement system fulfill the requirements described by IEC 61043 for a 100 mm spacer:
