14、 inside motor vehicles”, prepared by Subcommittee 1, Noise, of ISO Technical Committee 43, Acoustics, of the International Organization for Standardization (ISO). Terminology and conventions. The text of the International Standard has been approved as suitable for publication as a British Standard w
15、ithout deviation. Some terminology and certain conventions are not identical with those used in British Standards; attention is especially drawn to the following. The comma has been used throughout as a decimal marker. In British Standards it is current practice to use a full point on the baseline a
16、s the decimal marker. Wherever the words “International Standard” appear, referring to this standard, they should be read as “British Standard”. The Technical Committee has reviewed the provisions of ISO 1176:1974, ISO 1999:1975, ISO 2204:1979, and IEC Publication 225:1966 and has decided that they
17、are acceptable for use in conjunction with this standard. Related British Standards for ISO 1999:1975 and IEC Publication 225:1966 are BS 5330:1976 “Method of test for estimating the risk of hearing handicap due to noise exposure” and BS 2475:1964 “Octave and one third octave band-pass filters” resp
18、ectively. ISO 5131, referred to in clause 1 for information purposes only, is in course of preparation. NOTETextual errors. When adopting the text of the International Standard, the errors listed below were noticed and acknowledged by ISO/TC 43/SC 1. In paragraph 2 of 3.2, “type test” should be read
19、 as “verification test”, and in 4.2, “type and monitoring tests” should be read as “verification and monitoring tests”. A printing error in 8.4.2 has been corrected. A British Standard does not purport to include all the necessary provisions of a contract. Users of British Standards are responsible
20、for their correct application. Compliance with a British Standard does not of itself confer immunity from legal obligations.

23、engineering and contractual purposes. It specifies the conditions for obtaining reproducible and comparable measurements of the levels of the noise and the noise spectra inside all kinds of motor vehicles intended for road use, including those where the driver and/or passengers occupy an open cabin
24、or even only a well-defined area, but excluding agricultural tractors and field machinery covered by ISO 5131. The results may be used, for example: to decide whether or not the noise inside the vehicle is in accordance with noise specifications; to estimate hearing damage risk in conjunction with n
