Calibration Service - Acoustics
Traceable quality for acoustic measuring equipment
Trust a competent and DAkkS-accredited partner when it comes to the calibration of your acoustic measuring instruments. We calibrate your measuring microphones, sound level meters, sound level calibrators, pistonphones as well as a wide range of acoustic devices quickly and reliably.
In order to perform reliable measurements, your measuring equipment must be traced back or calibrated at regular intervals. This way you can ensure that you make reproducible measurements and improve their quality.

250 Hz (94 dB, 114 dB or 124 dB) and 1 kHz (94 dB or 114 dB)
Sound intensity probes
- Calibration of the relative free field frequency response of each microphone: 125 Hz...20 kHz
- Including two-point pressure chamber calibration: 250 Hz (124 dB) and 1 kHz (94 dB or 114 dB)
- Calibration of the phase frequency response in the pressure chamber to determine the residual intensity of the probe
- Conformity testing of the frequency response and the residual intensity against the limits defined in the standard DIN EN 61043:1994
By means of a two-channel technology, sound intensity probes enable, in addition to sound pressure level measurement, the recording of the sound pressure gradient and thus the calculation of the sound intensity.
