The relevance of the peak sound pressure level to the assessment of industrial workplaces

摘要

In addition to determination of the daily noise exposure level L_(ex,8h,) assessment of noise exposure at workplaces in accordance with EU Directive 2003/10/EC [1] may require measurement of the C-weighted peak sound pressure level L_(cpeak·) At the majority of workplaces, the daily noise exposure level L_(EX,8h),8h is the deciding quantity for assessment, and forms the basis upon which high-noise areas are marked, hearing protectors selected, and decisions taken regarding preventive hearing checks. Only at workplaces exhibiting extremely high impulsive sound events and peak sound pressure levels L_(Cpcak) of 135 dB and higher need the additional sound parameter of this peak level be considered.
