Free-field reciprocity calibrations of standard microphones.

Project Description

The project is a continuation of a similar BCR project between the same partners and which were finished by the end of 1992. In order to resolve the discrepancies observed during the BCR-project the partners will refine their measuring technique and a new intercomparison will be conducted. The program of measurement will be the same and the partners will calibrate the same microphones as used for the BCR intercomparison.
