Bibliography

Specifies the use of a series of nine International Standards those describing various methods for determining the sound power levels from all types of machinery and equipment. It provides: - 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. the guidance given a plies only to airbone sound. It is for use in the preparation of noise test codes and also in noise testing where no specific noise test code exist.
