National Institute for Airborne Acoustic Metrology

The National Institute of Airborne Acoustic Metrology (NIAAM) offers an independent microphone calibration service that represents the highest metrological level of microphone calibration in the UK:-

• UKAS accredited to BS EN ISO/IEC 17025: 2017 for the secondary calibration of pressure sensitivity of microphones to BS EN 61094-5: 2016 (Calibration Laboratory 0801)
• Using an LS2 microphone
• Expanded measurement UC (k=2) from 0.08 dB to 0.12 dB dependent on frequency.

For University of Salford standard acoustic calibrations of sound level meters, microphones and acoustic calibrators see our calibration page.
