Sound calibrators are stable sound sources designed to produce a known sinusoidal sound pressure of specified level and frequency when coupled to specified types and configurations of microphones. The sound pressure level generated by a calibrator will generally depend on the special microphone configuration used and may also depend on ambient parameters such as atmospheric pressure, temperature and humidity. This intercomparison is the third in a series of BCR intercomparisons on acoustic standards, the first one being an intercomparison of one-inch microphone pressure calibration and the second an intercomparison of half-inch microphone pressure calibration. The present study supplements and at the same time links the previous ones. Calibration techniques developed by participating laboratories are summarised and the results are described.
