1 Scope
This part of IEC 60645 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.
