Acoustics. Measurement of airborne noise emitted and structure-borne vibration induced by small air-moving devices - Airborne noise measurement Ingestion-build-276583 irrespective of the materials contained1 Scope This part of ISO 10302 specifies methods for measuring the airborne noise emitted by small air moving devices (AMDs), such as those used for cooling electronic, electrical, and mechanical equipment where the sound power level of the AMD is of interest. Examples of these AMDs include propeller fans, tube axial fans, vane axial fans, centrifugal fans, motorized impellers, and their variations. This part of ISO 10302 describes the test apparatus
