Abstract

The current Standards for sound level meters are at present being revised into a new singledocument, IEC 61672, which will contain specifications, tests and test methods. These test methods will cover both pattern evaluation of new models of sound level meters and periodic verification of individual specimens. The aim of this project was to perform trial sound level meter verifications using the draft of IEC 61672 current at the start of the project, and to report any problems encountered in interpreting the text or applying the tests to the IEC Working Group responsible for the new standard. In addition valuable data on uncertainties of measurement was sought. The project was organised through Euromet which is a forum for collaboration and research between national metrology institutes from countries within Europe. Twelve European institutes participated and this report gives details of the project and of the conclusions reported to the IEC Working Group.
