Acceptance code for gear units - Test code for airborne sound Ingestion-build-95349 are focused on the environmental1 Scope This part of ISO 8579 specifies the instructions and standardized conditions necessary for the determination of the airborne sound emission of gear units and gearmotors. It also specifies the allowed measurement methods, together with the operating and mounting conditions used for the test. The emission characteristics include emission sound pressure levels at specified positions and the sound power level. The determination of these quantities
