35、s International Standard specifies an engineering method (grade 2 accuracy) to determine the emission sound pressure level of machines in situ, at the work station or at other specified positions, using sound intensity. It is an alternative to ISO 11201, ISO 11202 and ISO 11204 for in situ measureme

36、nts. It is applicable to all kinds of test environments provided that the requirements on background noise and field indicators are fulfilled. This International Standard is applicable to equipment emitting stationary broadband noise. The noise can differ between operational cycles and can be with o

37、r without discrete frequency or narrow band components. 2 Normative references The following referenced documents are indispensable for the application of this document.
