This Standard specifies general requirements for equipment designed for use in determining hearing threshold levels, relative to standard reference threshold levels established by means of psychoacoustic test methods, and that designed to perform psychoacoustic tests using speech material (hereafter referred to as audiometers).

The object of this standard is to ensure :

a) that tests of hearing in the frequency range 125 Hz to 16 kHz on a given human ear, performed with different pure-tone audiometers which comply with this Standard, give substantially the same results;

b) that the results obtained represent a valid comparison between the hearing of the ear tested and the reference threshold of hearing;

c) that a means of presenting speech material to a subject in a standardized manner is provided. This will ensure that tests of hearing using a specific speech signal and a specific manner of signal presentation, when performed with different audiometers which comply with this Standard, give substantially the same results;

d) that audiometers are classified according to the range of test signals they present, according to the mode of operation or according to their presumed primary application.

NOTE The International Standard corresponding to this Standard and the symbol of degree of correspondence are as follows.

IEC 60645-1 : 2017 Electroacoustics — Audiometric equipment — Part 1 : Equipment for pure-tone and speech audiometry (MOD)

In addition, symbols which denote the degree of correspondence in the contents between the relevant International Standard and JIS are IDT (identical), MOD (modified), and NEQ (not equivalent) according to ISO/IEC Guide 21-1.
