Turbines and turbine sets. Measurement of emitted airborne noise. Engineering/survey method Ingestion-build-133579 — all major overhauls of1 Scope This document specifies methods for measuring the noise emission of a turbine or turbine set under steady state operating conditions. It specifies methods for measuring the sound pressure levels on a measurement surface enveloping a source, and for calculating the sound power level produced by the source. It gives requirements for the test environment and instrumentation, as well as techniques for obtaining the surface sound pressure level
