Scope
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 a semi.reverberant field. Emission sound pressure level are measured as A-weighted and, if required, C-weighted peak.NOTE 1 The contents of this and related International Standards are summarized in table 1 of ISO 11200:1995.A method is given for determining a local environment correction (subject to a specified limiting maximum value) to be applied to the measured sound pressure levels in order to exclude at least part of the effects of reflections from reflecting surfaces other than the plane on which the machinery or equipment is placed. This correction is based on the equivalent sound absorption area of the test room.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 enclsure remote from the source. One or more specified positions may be located in the vicinity of an attended or unattended machine. Such positions are sometimes referred to as bystander positions.This International Standard specifies requirements for the survey grade of accuracy on the test environment and instrumentation. Instructions are given for the installation and operation of the machine under test and for the choise 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 date obtained may also be used for the declaration and verification of emission sound pressure levels as specified in ISO 4871.
