适用范围
The document specifies a standard reference zero for the scale of hearing treshold level applicable to pure-tone air conduction audiometers, in order to promote agreement and uniformity in the expression of hearing treshold level measurements throughout the world. It states the information in a form suitable for direct application to the calibration of audiometers, that is, in terms of the response of two different standard models of earphone measured on a coupler complying with IEC 60303 and in terms of other supra-aural earphones of models specified in 4.3 measured on an aritficial ear complying with IEC 60318.#,,#
