Omfattning
This International Standard specifies a method for measuring the emission sound pressure levels of machinery and equipment, at a work station and at other specified positions nearby, in an essentially free field over a reflecting plane. A work station is occupied by an operator. It may be located in open space in the room where the source operates, or in a cab fixed to the source, or in an enclosure remote from the source. One or more specified positions may be located in the vicinity of a work station, or in the vicinity of an unattended machne. As some of these positions may be occupied occasionally of regularly, they are sometimes referred to as bystander positions.

Emission sound pressure levels are measured as A-weighted and, if required, C-weighted peak, and in frequency bands.

NOTE 1 The contents of this and related International Standards are summarized in table 1 of ISO 11200:1995.

The International Standard specifies requirements 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. The data obtained may also be used for the declaration and verification of emission sound pressure levels as specified in ISO 4871.
