Hearing protectors - Safety requirements and testing - Part 6: Ear-muffs with electrical audio input

This European Standard is concerned with ear-muffs whose passive acoustic performance may be augmented by an audio communications facility or circuit. It specifies additional constructional, design and performance requirements, methods of test, marking requirements and user information relating to the incorporation of the audio communications facility. The requirements of this standard are intended to take account of the ergonomic interaction between the wearer, the device and where possible the working environment in which the device is likely to be used (see Annex ZA, of this standard and EN 458).

Gehörschützer - Sicherheitstechnische Anforderungen und Prüfungen - Teil 6: Kapselgehörschützer mit Kommunikationseinrichtungen

Diese Europäische Norm behandelt Kapselgehörschützer, deren passive akustische Leistung durch eine Kommunikationseinrichtung oder -schaltung ergänzt wird. Er legt zusätzliche, für die Kommunikationseinrichtung geltende Anforderungen hinsichtlich Konstruktion, Gestaltung, Eigenschaften, Kennzeichnung und Benutzerinformationen fest und nennt entsprechende Prüfverfahren. Die Anforderungen dieser Norm haben das Ziel, die ergonomische Wechselwirkung zwischen dem Benutzer, dem Gerät und wo möglich der Arbeitsumgebung, in der das Gerät  voraussichtlich benutzt wird, zu berücksichtigen (siehe Anhang ZA dieser Norm und EN 458).

Protecteurs individuels contre le bruit - Exigences de sécurité et essais - Partie 6: Serre-tête avec entrée audio-électrique

La présente Norme européenne traite des serre-tête dont les performances acoustiques passives peuvent être améliorées par un circuit ou un dispositif à entrée audio-électrique pour des raisons essentielles de sécurité. Elle spécifie les exigences supplémentaires en matière de construction, de conception, de performances, les méthodes d'essai et les exigences de marquage ainsi que les informations destinées à l'utilisateur relatives à l'apport du dispositif à entrée audio-électrique.
Les exigences de la présente norme prennent en compte l'interaction ergonomique entre l'utilisateur, le dispositif et, lorsque cela est possible, l'environnement de travail auquel le dispositif est destiné (voir annexe ZA de la présente norme et l'EN 458).

Introduction
This standard for ”Hearing Protectors – safety requirements and testing – Part 6: Ear-muffs with electrical
audio input”, specifies procedures for the testing of personal hearing protection devices in relation to Directive
89/686/EEC - Personal Protective Equipment.
EN 352-1 deals with requirements for ear-muffs, EN 352-2 with ear-plugs, EN 352-3 with ear-muffs attached
to industrial safety helmets. EN 13819-1 and EN 13819-2 deal with testing plans common to all types of
hearing protectors covered by this series of ENs.
Additional safety requirements and the associated test procedures for level-dependent ear-muffs are
contained in EN 352-4, for ear-muffs with active noise reduction in EN 352-5 and for level-dependent ear-
plugs in EN 352-7. An associated standard EN 458, covers selection, use, care and maintenance of hearing
protection.
The particular requirement for hearing protectors in relation to their ability to reduce noise to below daily limit
levels set by Directive 86/188/EEC - "on the protection of workers from the risks related to exposure to noise at
work" is addressed in the standard by means of a requirement to report the output sound levels of the electrical
audio circuit.
An additional acoustic performance test method to that described in EN 24869-1 and applied in EN 352-1,
EN 352-2 and EN 352-3 is required for ear-muffs with electrical audio input. Until such time as this work is
completed, the test method described in Annex B of this standard is recommended for ear-muffs with electrical
audio input, in addition to the EN 24869-1 test required within EN 352-1.
Ear-muffs with electrical audio input are designed to provide speech information and warning signals, while
providing attenuation of sounds in excess of limit levels. They may be selected for use in a number of different
working environments, in air traffic communication, in the police forces, in the broadcasting and entertainment
industries, in intermittent or impulsive noise environments when speech information needs to be received and
where other warning signals are required to be heard.
This part of the standard is a specification intended for type approval purposes, for which four sets of specimen
ear-muffs are tested, (further samples may be required for testing under EN 351, or EN 352-3, as appropriate).
The requirements and tests of the standard are concerned primarily with the electrical audio input performance of
the ear-muffs. The standard may be applied to ear-muffs for fitting to industrial safety helmets.
1 Scope
This European Standard is concerned with ear-muffs whose passive acoustic performance may be supplemented
by an electrical audio input facility or circuit for essential safety-related purposes. It specifies additional
constructional, design and performance requirements, methods of test, marking requirements and user
information relating to the incorporation of the electrical audio input facility.
The requirements of this standard are intended to take account of the ergonomic interaction between the
wearer, the device and, where possible, the working environment in which the device is likely to be used (see
Annex ZA of this standard and EN 458)
