适用范围：This International Standard specifies a method for determining the emission sound pressure levels ofmachinery or equipment, at a work station and at other specified positions nearby, in an essentially free fieldover a reflecting plane. A work station is occupied by an operator and may be located in open space, in theroom where the source under test operates, in a cab fixed to the source under test, or in an enclosure remotefrom the source under test. One or more specified positions may be located in the vicinity of a work station, orin the vicinity of an attended or unattended machine. Such positions are sometimes referred to as bystanderpositions.Emission sound pressure levels are determined as A-weighted levels. Additionally, levels in frequency bandsand C-weighted peak emission sound pressure levels can be determined in accordance with this InternationalStandard, if required.NOTE 1 The contents of the series ISO 11200 to ISO 11205 are summarized in ISO 11200.With the method specified in this International Standard, results of accuracy grade 1 (precision grade) oraccuracy grade 2 (engineering grade) are obtained. Corrections are applied for background noise, but not forthe acoustic environment. Instructions are given for the mounting and operation of the source under test andfor the choice of microphone positions for the work station and for other specified positions. One purpose ofthe measurements is to permit comparison of the performance of different units of a given family of machines,under defined environmental conditions and standardized mounting and operating conditions.NOTE 2 The data obtained can also be used for the declaration and verification of emission sound pressure levels asspecified in ISO 4871
