Hearing protectors - Safety requirements - Part 7: Level-dependent earplugs

This European Standard is applicable to level-dependent earplugs. It specifies requirements on construction, design, performance, marking and user information related to the inclusion of the level-dependent functionality.

Gehörschützer - Sicherheitstechnische Anforderungen - Teil 7: Pegelabhängig dämmende Gehörschutzstöpsel

Dieses Dokument ist anzuwenden für pegelabhängige Gehörschutzstöpsel. Es legt für die Integration der pegelabhängigen Funktionalität Anforderungen hinsichtlich Konstruktion, Gestaltung, Leistung, Kennzeichnung und Benutzerinformationen fest.
Pegelabhängige Gehörschutzstöpsel sind dazu konstruiert, die Wiedergabe von Umgebungsgeräuschen zu ermöglichen, während sie bei hohen Pegeln eine Dämmung des Schalls bewirken. Sie können für die Anwendung in Umgebungen mit intermittierendem oder Impulslärm, in der gleichzeitig äußere akustische Warnsignale gehört werden müssen, eingesetzt werden. Dieses Dokument behandelt diejenigen Gehör¬schutzstöpsel, die mit einem elektronischen Schaltkreis für die Schallwiedergabe ausgestattet sind.

Protecteurs individuels contre le bruit - Exigences de sécurité et essais - Partie 7 : Bouchons d'oreilles à atténuation dépendante du niveau

Le présent document est applicable aux bouchons d'oreille à atténuation dépendante du niveau. Il spécifie les exigences en matière de construction, de conception, de performances et de marquage ainsi que les informations destinées à l'utilisateur pour ce qui concerne l'incorporation de la fonctionnalité d'atténuation dépendante du niveau.
Les bouchons d'oreilles à atténuation dépendante du niveau sont conçus pour restituer les sons externes tout en assurant l'affaiblissement de ceux à forts niveaux. Ils peuvent être choisis pour être utilisés dans des environnements de bruit intermittent ou impulsionnel ainsi que dans des lieux où il est nécessaire de percevoir d'autres signaux d'avertissement sonores. Le présent document concerne les bouchons d'oreilles équipés d'un circuit électronique de restitution du son.

prEN 352-7:2017 (E) 4 Introduction Level-dependent earplugs are designed to provide restoration of external sounds, while providing attenuation of sounds at high levels. They may be selected for use in intermittent or impulsive noise environments and where external warning sounds are required to be heard. This standard is concerned with those earplugs having an electronic sound restoration circuit. The requirements of the standard are concerned primarily with the level-dependent performance of the earplugs. EN 352-7 is part of a family of standards describing product requirements: — 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 and testing — Part 4: Level-dependent earmuffs — EN 352-5, Hearing protectors — Safety requirements and testing — Part 5: Active noise reduction earmuffs — EN 352-6, Hearing protectors — Safety requirements and testing — Part 6: Earmuffs with safety-related audio input — EN 352-7, Hearing protectors — Safety
