Microphones & Acoustic Sensors

The measurement microphone sets have been combined so they fulfil our users’ typical measurement needs. Independently of your measurement system and application you should be able to find a set that suits your needs.

GRAS measurement microphones are available in many types covering various frequency ranges, dynamic ranges and suiting differerent application situations.

The output from a condenser microphone is a very high-impedance signal and is therefore very sensitive to the capacitive loads of cables. This makes it necessary to introduce a driver with high input impedance and low output impedance. Such a driver is called a preamplifier.

Special microphones are often required for applications where there are particular requirements regarding the methods of measurements and configurations.
