Basics of measurement: practical implementations

摘要

More than 40 delegates attended the one-day meeting at the Building Research Establishment, Watford, in November, arranged by the Measurement & Instrumentation Group, with presentations on nine different topics. These were developed from the articles which have appeared in Acoustics Bulletin, under the regular Instrumentation Corner feature. In the main, the speakers were members of the group committee, chaired by Richard Tyler. The meeting kicked off with Sue Dowson from NPL presenting an overview of international and British standards and the process by which these are developed. The key standards for sound level meters and calibrators were described, and how instruments are testing to specifications. Sue also described the current status of BS EN 61672, which is being updated, and the implications for the users.
