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
