Annex A - Recommended units and terms
Covers instruments designed primarily for the measurement of modulus of acoustic impedance/ admittance in the human external acoustic meatus using a probe tone of 226 Hz. Defines the characteristics to be specified by the manufacturer, lays down performance specifications for four types of instrument and specifies the facilities to be provided on three of these types. Methods of test to be used for approval testing rather than routine calibration are also specified.
