Introduction
This standard is part of a set of standards for personal hearing protectors.
The EN 13819 series consists of three parts and deals with testing plans of hearing protectors.
— 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
The product requirements are described in a family of standards:
— 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
— EN352-6, 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
This standard also provides informative spreadsheets with
— calculation examples for level-dependent earplugs
— calculation examples for ANR
to allow the user to make own calculations.
CEN is not responsible for errors that may arise or occur with the use of these spreadsheets.
An associated standard, EN 458, covers selection, use, care and maintenance of hearing protectors.
1 Scope
This document specifies supplementary acoustic test methods for hearing protectors with additional
electronic functions. The purpose of these tests is to enable assessment of the hearing protector
performance as specified in the appropriate product standards.
