Reciprocating internal combustion engines. Measurement of sound power level using sound pressure - Engineering method1 Scope This document specifies the engineering method, which is the measurement method of the sound power level for reciprocating internal combustion engines. This document applies to all reciprocating internal combustion engines falling within the field of application of ISO 30461 and other internal combustion engines where no suitable International Standard exists. NOTE In this document, reciprocating internal combustion engines are referred to as
