適用范圍：This International Standard specifies procedures for measuring and reporting the noise emission of computer and business equipment. It is based on the measurement procedures defined in ISO 3740, ISO 3741, ISO 3742 and ISO 3744. 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.The sound power level is supplemented by the A-weighted sound pressure level measured at the operator position(s) or the bystander position(s). This level is not a measurement of total occupational noise exposure of workers (noise immission). However, the data obtained may assist in identify-ing any potential problems that could cause annoyance, activity interference or hearing damage to operators and bystanders.
