Electroacoustics - Audiometric equipment - Part 6: Instruments for the measurement of otoacoustic emissions
IEC 606045-6:2022 applies to instruments designed primarily for the measurement of otoacoustic emissions in the human external auditory meatus evoked by acoustic probe stimuli. This document defines the characteristics to be specified by the manufacturer, specifies minimum mandatory functions for two types of instruments and provides performance specifications applicable to both instrument types. This document describes methods to be used to demonstrate conformance with the specifications in this document and guidance on methods for periodic calibration. The purpose of this document is to ensure that measurements made under comparable test conditions with different instruments complying with this document will be consistent. Instruments can provide a measurement function not specifically within the scope of this document and still comply with the relevant requirements of this document for the functions that are within the scope. This document is not intended to restrict development or incorporation of new features, nor to discourage innovative approaches. IEC 606045-6:2022 cancels and replaces the first edition published in 2009. This edition constitutes a technical revision.This edition includes the following significant technical changes with respect to the previous edition:a) the nominal test frequency used in DPOAE is now defined as the higher of the two frequencies, f2;b) the permitted deviation of the stimulus signal for TEOAE has been specified;c) the frequency range for DPOAE stimulus signals has been redefined,d) the stimulus level requirements for TEOAE have been redefined;e) the stimulus level requirements for DPOAE have been redefined;f) the harmonic distortion requirements for DPOAE have been redefined;g) a minimum measurement range for DPOAE has been added.

Electroacoustics - Audiometric equipment - Part 6: Instruments for the measurement of otoacoustic emissions
IEC 60645-6:2009 applies to instruments designed primarily for the measurement of otoacoustic emissions in the human external acoustic meatus evoked by acoustic probe pulses or tones. This standard defines the characteristics to be specified by the manufacturer, lays down performance specifications for two types of instruments and specifies the functions to be provided on these types. IEC 60645-6:2009 describes methods of test to be used for approval testing and guidance on methods for undertaking routine calibration. The purpose of IEC 60645-6:2009 is to ensure that measurements made under comparable test conditions with different instruments complying with the standard will be consistent. Instruments which provide a measurement function not specifically within the scope of the standard shall still comply with any relevant requirements. This standard is not intended to restrict development or incorporation of new features, nor to discourage innovative approaches.
