BS 3539 is an International Standard that discusses the aspects of good quality sound level meters that are used for motor vehicles.
BS 3539 specifies the requirements for sound level meters for the measurement of noise emitted by motor vehicles, the procedure for laboratory verification of their accuracy and the information to be shown on a calibration certificate.
BS 3539 on sound level meters specification is useful for:
A sound level meter is a combination of a microphone, a preamplifier, a signal processor, and a display device that is used for measuring the noise emitted from motor vehicles.
BS 3539 lays down the technicalities for sound level meters used for motor vehicles, that follow global standards. BS 3539 covers the requirements for the meters and assists with the procedure for laboratory verification for sound level meters. BS 3539 also leads for information to be provided in the calibration certificate of the sound level meters.
Overall, BS 3539 helps the users to manufacture the best quality, highly efficient, and precise sound level meters on which one can rely and measure the noise emitted accurately.
BS 3539 is a step towards monitoring and reducing sound pollution, which improves the quality of life for those around noise pollution sources.
