Bibliography

Provides guidance for the use of a series of nine International Standards describing various methods for determining the sound power levels from all types of machinery and equipment. Gives: - brief summaries of these basic International Standards; - guidance on the selection of one or more of these standards which are appropriate to any particular type.
