This article is designed to help the automobile engineer to become familiar with the techniques, units, and language of acoustics and noise control for use in implementing legislation that limits the amount of noise a vehicle may emit. Regulation 23 of the Motor Vehicles (Construction and Use) Regulations 1969 is an example of such legislation in the UK. Under these regulations, the noise emitted by vehicles must be measured in accordance with the method prescribed in B.S. 3425:1966 and the sound levels must not exceed the specified limits, expressed in dBA. The test site for this full throttle acceleration test is described in the article along with the conditions for measurement.
