Title Acoustics - Noise emitted by machinery and equipment - Measurement of emission sound pressure levels at a work station and at other specified positions - Engineering method in an essentially free field over a reflecting plane
Original title Acoustique - Bruit émis par les machines et équipements - Mesurage des niveaux de pression acoustique d'émission au poste de travail et en d'autres positions spécifiées - Méthode d'expertise dans des conditions approchant celles du champ libre sur plan réfléchissant [in French]

Abstract This international standard specifies a method for measuring the emission sound pressure levels of machinery and equipment, at a work station occupied by an operator and at other specified positions nearby, in an essentially free field over a reflecting plane. Requirements are specified for the engineering grade of accuracy on the test environment and instrumentation. Corrections are applied for background noise, but not for the acoustic environment. Instructions are given for the installation and operation of the machine under test and for the choice of microphone positions for the work station and for other specified positions. The purpose of the measurements is to permit comparison of the performance of different units of a given family of machinery or equipment, under defined environmental conditions and standardized mounting and operating conditions.
