Sound Level Calibration: Microphones, Ear Simulators, Couplers, and Sound Level Meters
Lee Grason, Dr.-Ing. Thomas Fedtke · Seminars in Hearing · 2014
This article describes the instrumentation used for the calibration of audiometric equipment and how the sound level measurements are traced back to national/international references. Couplers and ear simulators are crucial for the measurement of the output of audiometric transducers. Therefore, special attention is given to their specification, application, and testing.
