European foreword
This document (EN 13819-2:2020) 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 2021, and conflicting national standards shall be
withdrawn at the latest by May 2021.
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 will supersede EN 13819-2:2002.
In comparison with the previous edition, the following technical modifications have been made:
— 4.2.3 some details on the test procedure for the sound attenuation of earplugs and custom moulded
earplugs added;
— 4.3 of EN 13819-2:2002 (Sound level effective to the ear (earmuffs only)) deleted;
— Annex ZA of EN 13819-2:2002 deleted.
The technical changes referred to include the significant technical changes from the European Standard
revised but is not an exhaustive list of all modifications from the previous edition.
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

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.
1 Scope
This document specifies acoustic test methods for hearing protectors. The purpose of these tests is to
enable assessment of the performance of the hearing protector as specified in the appropriate product
standard.
