ASA S3.25 – American National Standard for an Occluded Ear Simulator
The acoustical performance of an occluded ear simulator is specified. This device is designed tosimulate the acoustical behavior of the ear canal between the tip of an ear mold and the eardrum,including the acoustic impedance at the eardrum of a median adult human ear. The occluded earsimulator is intended for transducers that are sensitive to acoustic load. It is also suitable as the basisfor extensions intended to simulate the complete ear canal and the outer ear (e.g., head and torsosimulators). Specific physical realizations of the ear simulator are described.
