Acoustics. Determination of airborne sound power levels emitted by machinery using vibration measurement - Survey method using a fixed radiation factor Ingestion-build-78747 BS EN 81-2:1998+A3:2009 looks at1 Scope This part of ISO TS 7849 gives basic requirements for reproducible methods for the determination of an upper limit for the A weighted sound power level of the noise emitted by machinery or equipment by using surface vibration measurements. The method is only applicable to noise which is emitted by vibrating surfaces of solid structures and not to noise generated aerodynamically. This vibration measurement method is especially applicable in
