Pressure chamber calibration for microphones

Akustischer Kuppler

Measurement microphones have so far only been calibrated with a one- or two-point calibration using a calibrator but can now be examined over the entire frequency range using the SPEKTRA SQ-4.1/4.2.

Possible variations in the frequency response may not become visible by examining only one single point. A comprehensive study of the frequency response makes them visible.

Details to the electro-acoustic coupler can be found here.
