This part of ISO 8253 specifies relevant test signal characteristics, requirements for free, diffuse, and
quasi-free sound fields, and procedures for sound field audiometry using pure tones, frequency-modulated
tones or other narrow-band test signals presented by means of one or more loudspeakers. The primary
purpose is the determination of hearing threshold levels in the frequency range 125 Hz to 8 000 Hz, but this
range can be extended to 20 Hz to 16 000 Hz.
This part of ISO 8253 does not include specifications for the use of hand-held loudspeakers. Speech as a test
signal is not covered.
The purpose of this part of ISO 8253 is to ensure that tests of hearing, using sound field audiometry, give as
high a degree of accuracy and reproducibility as possible.
Examples of graphical representations of the results are given in Annex A.
