Introduction of GB/T 17249.1-1998

1 Scope This standard outlines strategies to be used in dealing with noise problems in existing and planned workplaces by describing basic concepts in noise control. It includes those important strategies to adopt when buying a new machine or equipment. This standard is applicable to all types of workplaces containing machinery. 2 Normative References The following standards contain provisions which, through reference in this text, constitute provisions of this standard. At the time of publication, all the editions listed were valid.
