The MI19-HS is the first 1/4″ measuring microphone with a sensitivity of 100 mV/Pa and a self-noise of 24 dB(A).
The high signal-to-noise ratio and high sensor sensitivity optimize the dynamic range of the measurement data acquisition, resulting in better measurement results.
Standard 1/4″ measuring microphones with prepolarized capsules deliver a voltage of 3 to 5 mV/Pa and have a self-noise of about 35 dB(A).
In contrast, the MI19-HS has a twenty times higher output voltage and 11 dB lower inherent noise at 24 dB(A).

We offer complete solutions from microphones to analysing and monitoring acoustic signals for industry, research and development.
We measure sound levels below 6.5 dBA, which are designed for measuring very quiet sound sources.
Noises with sound levels above 186 dB, such as those generated by rocket engines or firearms, can be measured without distortion using our 1/4″ microphones.
Our class 1 microphones are calibrated and traceable to national and international standards to ensure consistent and precise measurement results.
Sound level meters for extremely loud noises up to 186 dB as well as multi-channel data acquisition systems, e.g. for sound power measurement, and impedance tube systems round off our range.
