Acoustics - Measurement of airborne noise emitted by information technology and telecommunications equipment

This International Standard specifies procedures for measuring and reporting the noise emission of*information technology and telecommunications equipment.*NOTE 1 This International Standard is considered part of a noise test code (see 3.1.2) for this type of equipment, and is based on basic noise emission standards (see 3.1.1) ISO 3741, ISO 3744, ISO 3745 and ISO 11201.*The basic emission quantity is the A-weighted sound power level which may be used for comparing*equipment of the same type but from different manufacturers, or for comparing different equipment.*Three basic noise emission standards for determination of the sound power levels are specified in this*International Standard in order to avoid undue restriction on existing facilities and experience. ISO 3741*specifies comparison measurements in a reverberation test room; ISO 3744 and ISO 3745 specify*measurements in an essentially free field over a reflecting plane. Any one of these three basic noise emission standards can be selected and used exclusively in accordance with this International Standard when determining sound power levels of a machine.
