Acoustics. Procedure for the comparison of noise-emission data for machinery and equipment Ingestion-build-68772 evaluatingBS EN ISO 11689: 1996 Acoustics. Procedure for the comparison of noise emission data for machinery and equipment BS EN ISO 11689 specifies a method for establishing the noise control performance of machinery or equipment on the basis of noise emission data. It applies to any kind of machinery or equipment for which a noise test code exists or comparable noise emmission data is available. The general procedure specified in BS EN ISO 11689 can also be
