— Part 3: Supplementary acoustic test methods
An associated standard EN 458 covers selection, use, care and maintenance of hearing protectors.
This standard is intended as a supplement to the specific product standards for hearing protectors.
The performance requirements are given in the hearing protector product standard.
If deviations from the procedures specified in this standard are necessary, these deviations are
specified in the hearing protection product standard (relevant part of the EN 352 series).
4.1 specifies a method of measuring the insertion loss of earmuffs using an acoustic test fixture.
4.2 specifies a method of measuring the sound attenuation of hearing protectors using human test
subjects.
