your own acoustic calibration lab


All the equipment needed to build up your own Calibration Laboratory is available as off-the-shelf products from Norsonic.
Acoustical and electrical calibration of sound measuring instruments, measuring microphones and sound calibrators in accordance with the applicable traceable standards.

Periodic Verification of Sound Calibrators

  • Sound pressure level corrected for pressure, temperature and humidity
  • Short term stability expressed in dB (option)
  • Output frequency in Hz
  • Total distortion in % (option)

Periodic Verification of Sound Level Meters
The Periodic Verification of Sound Level Meters can be performed in accordance with several national and international standards. This includes measurements of:

  • Accuracy of input range selector
  • Level linearity
  • Spectral weighting networks A, B, C, Z, Lin and Flat
  • F, S, and I time constants. Pulse measurement capability
  • RMS detector capability
  • Overload detector
  • Inherent noise using microphone equivalent or acousti-cally insulated test vessel
  • Integrating averaging functions Leq and SEL
  • Noise dose
  • 1/1 and 1/3 octave band filters (option)
