microphone for high sound pressure levels 60 dBA - 186 dB

The 1/4″ microphone set consisting of the MP30 Set and the microphone capsule MK342 E has a constant pressure curve and is therefore optimized for correct acoustic measurements at interfaces or in acoustic couplers with extreme sound pressure levels.

1/4" IEPE microphone with
constant pressure frequency response

The static air pressure is compensated by means of a capillary to the preamplifier (back-ventilated) or by means of a side capillary (side-ventilated).

The membrane is protected against mechanical
damage by a protective grid.
