Anotace
This part of IEC 60645 applies to instruments designed primarily for the measurement of acoustic impedance/admittance in the human external auditory meatus using a stated probe tone. It is recognized that other probe signals may also be used. This document defines the characteristics to be specified by the manufacturer, lays down performance specifications for three types of instruments and specifies the facilities to be provided on these types. This document describes methods of test to be used for approval testing and guidance on methods for undertaking routine 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. This document is not intended to restrict development or incorporation of new features, nor to discourage innovative approaches.
