Scope: <p>This part of <std><std-ref>ISO 8253</std-ref></std> 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.</p><p>This part of <std><std-ref>ISO 8253</std-ref></std> does not include specifications for the use of hand-held loudspeakers. Speech as a test signal is not covered.</p><p>The purpose of this part of <std><std-ref>ISO 8253</std-ref></std> is to ensure that tests of hearing, using sound field audiometry, give as high a degree of accuracy and reproducibility as possible.</p><p>Examples of graphical representations of the results are given in <xref ref-type="app" rid="sec_A">Annex A</xref>.</p>
