Calibration Service – Audiometry

Accredited calibration of audiometric measuring equipment

We offer services at the highest technical level for the calibration of acoustic measuring equipment. We can also calibrate audiometric calibration devices for medical engineering such as artificial mastoids and ear simulators (DAkkS-certified) and trace them back to the national standard.

You determine the calibration interval. It depends on the application of the sensors. We would be happy to advise you on suitable intervals for your instruments!

  • Calibration in an accredited laboratory (German DAkkS)
  • Services at the highest level
  • Lowest possible measurement uncertainty
  • Traceability and reproducible measurements
  • Short processing time of 5-7 working days
  • Optional: express calibration within 48 h
