About This Item

 

Full Description

The physical configuration and acoustical performance of an occluded ear simulator are specified. This device is designed to simulate the acoustical behavior of that portion of the ear canal between the tip of an earmold and the eardrum, including the acoustic impedance at the eardrum of a median adult human ear over the frequency range from 100 Hz-10 kHz. The occluded ear simulator is suitable especially for transducers that are sensitive to acoustic load. Specific physical realizations of the ear simulator are described.

This standard reaffirmed on 15 October 2003.
