45、n. DIN EN ISO 11201:2010-10 EN ISO 11201:2010 (E) Introduction This International Standard specifies a method for determining the emission sound pressure levels at a work station and at other well defined positions, in the vicinity of a machine or piece of equipment, in an essentially free field ove
46、r a reflecting plane. It is one of a series (ISO 1120015to ISO 1120519) which specifies various methods for determining the emission sound pressure level at a work station and at other specified positions of a machine or equipment. ISO 1120015gives guidance on the choice of the method to be used to
47、determine the emission sound pressure levels of machinery and equipment. The method specified in this International Standard differs from those in other International Standards in the ISO 1120015to ISO 1120519series in not applying any environmental correction. Requirements to be fulfilled by the en
48、vironment are specified for accuracy grade 1 (precision) and grade 2 (engineering) measurements indoors and outdoors. Precision measurements with accuracy grade 1 can generally be carried out in hemi-anechoic test rooms or outdoors provided that requirements on environmental conditions are met. With
49、 the specifications defined in the following it should be possible in some cases to provide such conditions in industrial ambience on larger plane areas outdoors free from reflecting objects. ISO 11201:1995 provided results of accuracy grade 2 only. This edition of this International Standard provides a method of accuracy grade 2 that is essentially identical to that given in ISO 11201:1995. It also provides a more precise method of
