Abstract : Conclusions: The audiometrist should initially check an instrument for obvious defects as it comes from the factory, and should monitor it continuously as best he can with his own or other normal ears, or with an artificial ear if available, remembering that intensity output is only one of a half-dozen equally important aspects which may lose calibration. Only a facility which serves many clinics (approximately 500 audiometers) should hire an electroacoustic technician-audiologist team, and install and maintain the approximately $10,000. worth of calibration equipment necessary in a complete secondary calibration center. A primary calibration center should monitor the instruments and procedures of the secondary centers, and could serve as a research laboratory to refine the calibration procedures and as an informal exchange library for research data in this limited area.
