BS EN 60645-1:2017 specifies general requirements for audiometers designed for use in
determining hearing threshold levels, relative to standard reference threshold levels
established by means of psychoacoustic test methods, and those designed to perform
psychoacoustic tests using speech material.
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.
