Acoustics — Pure tone air conduction threshold audiometry for hearing conservation purposes
This part of ISO 8253 specifies procedures and requirements for pure-tone air conduction and bone conduction threshold audiometry. For screening purposes, only pure-tone air conduction audiometric test methods are specified. It is possible that the procedures are not appropriate for special populations, e.g. very young children. This part of ISO 8253 does not cover audiometric procedures to be carried out at levels above the hearing threshold levels of the subjects. Procedures and requirements for speech audiometry, electrophysiological audiometry, and where loudspeakers are used as a sound source are not specified.
Acoustics -- Audiometric test methods -- Part 1: Basic pure tone air and bone conduction threshold audiometry
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.
Acoustics -- Audiometric test methods -- Part 2: Sound field audiometry with pure tone and narrow-band test signals
The document describes in a comprehensive form the relation between annoyance, mental strain and stress caused by noise and their influence on health, well-being and efficiency of different working activities. It is broken down in the main-clauses: terms, influence factors, effects of noise immission and assessment of impact noise. It recommends directly or by reference characteristic noise values for planning or reconstruction purposes. Objective of this document is to enhance the efficiency and to improve the well-being in the working environment.
