• One laboratory for both sound & vibration measurements
• UKAS-Accredited acoustic calibration
• Turnround time typically 7 working days
• All measurements traceable to National Standards

We offer the following standard services:

UKAS-accredited acoustic calibration of sound calibrators and pistonphones and of sound level meters to Technical Guide NPL Acoustics 2004/1 or to BS 7580:Part 1:1997 as required.

Calibration of octave band and third octave band filters designed in accordance with either IEC 61260:1996 (classes 0, 1 or 2) or IEC 225:1966 which are fitted to sound level meters.

Frequency response and linearity of Noise Recording Instrumentation (e.g. DAT recorders, tape and cassette recorders, minidisc and other digital recorders)

AV Calibration was the first calibration laboratory to be awarded UKAS accreditation for testing filters fitted to sound level meters and offers a range of options, including full testing of filters used for compliance testing of new buildings.

It is also the first calibration laboratory to be awarded UKAS accreditation for periodic testing in accordance with Technical Guide NPL Acoustics 2004/1 for Class 1 and 2 sound level meters originally manufactured in accordance with IEC 61672-1:2002 for ANY make of sound level meter. It is also currently the ONLY UKAS-accredited laboratory offering customers calibration of noise recording instrumentation.

Traceable acoustic calibration of instrumentation, including sound calibrators, sound level meters, personal sound exposure meters ("dosemeters") and microphones. Performance checks on filter sets and DAT-recorder based measurement systems. These calibrations are not UKAS accredited.

Traceable calibration of vibration instrumentation, including vibration calibrators, vibration meters, accelerometers and filter sets. These calibrations are not UKAS accredited.
