PRESSURE SENSITIVITY CALIBRATION OF 1 INCH MICROPHONES BY THE RECIPROCITY TECHNIQUE
An intercomparison involving five other primary calibration laboratories within the EEC has been carried out with NPL acting as the Reporting Laboratory. Detailed results obtained from the calibration of ten Bruel and Kjaer microphones Type 4160 using the closed coupler reciprocity technique over the range 63 Hz to 12.5 kHz are presented. Pressure sensitivity levels measured prior to the dispatch of two microphones to each of the participating countries are compared with those obtained following their return to NPL, whilst the mean value for each microphone is compared with that reported by the relevant Contributing Laboratory.
