Introduction

This document specifies procedures for the testing of personal hearing protection devices in relation to

Regulation (EU) 2016/425 - Personal Protective Equipment.

A series of standards EN 352 describes product requirements of hearing protectors:

— EN 352-1, Hearing protectors — General requirements — Part 1: Earmuffs
— EN 352-2, Hearing protectors — General requirements — Part 2: Earplugs

— EN 352-3, Hearing protectors — General requirements — Part 3: Earmuffs attached to head

protection and/or face protection devices

— EN 352-4, Hearing protectors — Safety requirements — Part 4: Level-dependent earmuffs

— EN 352-5, Hearing protectors — Safety requirements — Part 5: Active noise reduction earmuffs

— EN 352-6, Hearing protectors — Safety requirements — Part 6: Earmuffs with safety-related audio

input

— EN 352-7, Hearing protectors — Safety requirements — Part 7: Level-dependent earplugs

— EN 352-8, Hearing protectors — Safety requirements — Part 8: Entertainment audio earmuffs

— EN 352-9, Hearing protectors — Safety requirements — Part 9: Earplugs with safety-related audio

input

— EN 352-10, Hearing protectors — Safety requirements — Part 10: Entertainment audio earplugs

Test methods for these requirements are described in the series of standards EN 13819:

— EN 13819-1, Hearing protectors — Testing — Part 1: Physical test methods
— EN 13819-2, Hearing protectors — Testing — Part 2: Acoustic test methods

— EN 13819-3, Hearing protectors — Testing — Part 3: Supplementary acoustic test methods

An associated standard EN 458 covers selection, use, care and maintenance of hearing protectors.

EN 13819-2 is intended as a supplement to the specific product standards for hearing protectors.

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.

The performance requirements are given in the hearing protector product standard.
