European foreword
This document (EN 13819-3:2019) has been prepared by Technical Committee CEN/TC 159 “Hearing
protectors”, the secretariat of which is held by DIN.
This European Standard shall be given the status of a national standard, either by publication of an
identical text or by endorsement, at the latest by May 2020, and conflicting national standards shall be
withdrawn at the latest by May 2020.
Attention is drawn to the possibility that some of the elements of this document may be the subject of
patent rights. CEN shall not be held responsible for identifying any or all such patent rights.
This document has been prepared under a standardization request given to CEN by the European
Commission and the European Free Trade Association.
According to the CEN-CENELEC Internal Regulations, the national standards organisations of the
following countries are bound to implement this European Standard: Austria, Belgium, Bulgaria,
Croatia, Cyprus, Czech Republic, Denmark, Estonia, Finland, France, Germany, Greece, Hungary, Iceland,
Ireland, Italy, Latvia, Lithuania, Luxembourg, Malta, Netherlands, Norway, Poland, Portugal, Republic of
North Macedonia, Romania, Serbia, Slovakia, Slovenia, Spain, Sweden, Switzerland, Turkey and the

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.
