Sound Calibrators

Sound calibrators produce a known tone at a known sound pressure level so you can check and adjust a sound level meter before and after measurements. The units listed produce reference levels such as 94 dB and 114 dB, and some listings include a traceable calibration certificate.

Confirm the microphone diameter the calibrator fits, the reference levels and frequency, and the accuracy class. IEC 60942 covers sound calibrators. Request a quotation from TSA; we ship worldwide, DDP.
