1 Scope This part of GB/T 17249 deals with the technical aspects of noise control in workplaces. The various technical measures are stated, the related acoustical quantities described, the magnitude of noise reduction discussed and the verification methods outlined. This part deals only with audible sound. Note: The bibliography lists relevant Standards and literature on noise control measures. 2 Normative references The following part contains provisions which, through reference in this text, constitute provisions of this part. For dated references, subsequent amendments to (excluding corrigendum), or revisions of, any of these publications do not apply. However, parties to agreements based on this part are encouraged to investigate the possibility of applying the most recent editions of the standards indicated below. For undated references, the latest editions apply to this part. GB/T 17249.1—1998 Acoustics-Guidelines for the design of low-noise workplaces-Noise control planning (eqv ISO 11690-1：1996) 3 Terms and definitions All definitions in Clause 3 of GB/T 17249.1—1998 Acoustics-Guidelines for the design of low noise workplaces-Noise control planning are applicable to this part. 4 Technical general of noise control Noise reduction measures can be applied at source (emission), between the source and the receiver (transmission path), and at the work station (receiver). (See Figure 1.)
