This document specifies a relatively simple engineering method for determining the sound power levels of small, movable noise sources. The methods specified in this document are suitable for measurements of all types of noise within a specified frequency range, except impulsive noise consisting of isolated bursts of sound energy which are covered by ISO 3744 and ISO 3745.Cross References:ISO 3741IEC 61672-1ISO 6926ISO 5725 (all parts)IEC 61260 (all parts)ISO 3743-1ISO/IEC Guide 98-3IEC 60942ISO 3745ISO 3740ISO 3747ISO 11201ISO 9613-1ISO 4871ISO 1996-1ISO 7574-4ISO 9296ISO 3744ISO 3746ISO 12001ISO 7574-1ISO 7574-2ISO 354:2003All current amendments available at time of purchase are included with the purchase of this document.
