Acoustic Calibrators

Acoustic Calibrators to perform Field Calibrations on Sound Meters

When you're ready to take noise measurements, it's strongly recommended that you perform a field calibration using an Acoustic Calibrator. You should calibrate your sound meter before you start to measure, and then once you've finished you should perform a reference check against the calibrator and make note of any drift that has occured. You can find out more about performing Field Calibrators by reading this post and watching a short video.

Annual Calibration by a Traceable Laboratory

LAB23, the latest guidances from the United Kingdom Accrediation Service (UKAS), states the recommended calibration intervals for different types of measuring equipment, including:

  • Personal Dosemeters - 1 Year
  • Microphones (Reference and Workng) - 2 Years
  • Sound Meters (tested to BS7580, where applicable) 2 Years
  • Sound Meters build to IEC 61672 - 2 Years
  • All other Sound Meters - 1 Year
  • Acoustic Calibrators - 1 Year
