| 1 | This document establishes limits for permissible ambient noise in audiometric test rooms and specifies the methods of measurement to be used. Within this standard, maximum permissible ambient sound pressure levels and their measurement are specified for performing hearing threshold measurements via: – Pure-tone air conduction audiometry by means of various earphones; – pure-tone bone conduction audiometry by means of bone vibrator; – sound field audiometry by means of one or more loudspeakers; primarily over the test frequency range of 125 Hz to 8 000 Hz. The document also specifies ambient noise requirements for performing speech audiometry. The purpose of this document is to ensure that tests of hearing in audiometric test rooms are as accurate and reproducible as possible and are not influenced by the masking effects of ambient noise. | |
