Foreword
Introduction
1 Scope
2 Normative references
3 Definitions
4 Measurement of sound attenuation of hearing protectors
5 Calculation of the assumed protection value APV[fx] of a
hearing protector for a selected protection performance
6 Octave-band method
7 HML method
8 SNR method
Annex A (informative) Example of the calculation of the
assumed protection values, APV[fx]
Annex B (informative) Example of the calculation of L'[Ax]
according to the octave-band method
Annex C (informative) Example of calculation and use of H,
M and L values
Annex D (informative) Example of the calculation and use
of SNR values
Annex E (informative) Bibliography
Specifies three methods (the octave-band, HML and SNR methods) of estimating the A-weighted sound pressure levels effective when heating protectors are worn.
