BS EN ISO 11201-2010声学.机器和设备发射的噪声.在一个反射平面上方可忽略环境校正条件下进行工作位置和其他指定位置的发射声压级测量

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

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 any environment whichmeets certain qualification requirements. A work station is occupied by an operator and may be located inopen space, in the room where the source under test operates, in a cab fixed to the source under test, or in anenclosure remote from the source under test. One or more specified positions may be located in the vicinity ofa work station, or in the vicinity of an attended or unattended machine. Such positions are sometimes referredto as bystander positions.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.A method is given for determining a local environmental correction (subject to a specified limiting maximumvalue) to be applied to the measured sound pressure levels to exclude the effects of reflections from reflectingsurfaces other than the plane on which the source under test is placed. This correction is based upon themean sound pressure level on a measurement surface, the sound pressure level measured at a specifiedposition, and either an environmental correction or the equivalent absorption area of the test room.With the method specified in this International Standard, results of accuracy grade 2 (engineering grade) oraccuracy grade 3 (survey grade) are obtained. Corrections are applied for background noise and, asdescribed above, for the acoustic environment. Instructions are given for the mounting and operation of thesource under test and for the choice of microphone positions for the work station and for other specifiedpositions. One purpose of the measurements is to permit comparison of the performance of different units of agiven family of machines, under defined environmental conditions and standardized mounting and operatingconditions.NOTE 2 The data obtained can also be used for the declaration and verification of emission sound pressure levels asspecified in ISO 4871.
