Hearing protectors - Safety requirements - Part 5: Active noise reduction earmuffs

This European Standard is applicable to active noise reduction (ANR) earmuffs. It specifies requirements on construction, design, performance, marking and user information related to the inclusion of the active noise reduction facility.

Gehörschützer - Sicherheitstechnische Anforderungen - Teil 5: Kapselgehörschützer mit aktiver Geräuschkompensation

Dieses Dokument ist anzuwenden für Kapselgehörschützer mit aktiver Geräuschkompensation (ANR, en: Active Noise Reduction). Es legt für die Integration der aktiven Geräuschkompensation Anforderungen hinsichtlich Konstruktion, Gestaltung, Leistung, Kennzeichnung und Benutzerinformationen fest.
Kapselgehörschützer mit aktiver Geräuschkompensation haben die Aufgabe, mit Hilfe einer das Geräusch „auslöschenden“ Schaltung eine zusätzliche Schalldämmung der Umgebungsgeräusche zu bewirken. Diese zusätzliche Schalldämmung wird üblicherweise für tiefe und mittlere Frequenzen bereitgestellt. Sie sind für den Einsatz in tieffrequentem Lärm mit hohen Schallpegeln geeignet.

Protecteurs individuels contre le bruit - Exigences de sécurité et essais - Partie 5 : Serre-tête à atténuation active du bruit

Le présent document est applicable aux serre-tête à atténuation active du bruit (ANR). 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 du dispositif d'atténuation active du bruit.
Les serre-tête à atténuation active du bruit sont conçus pour assurer un affaiblissement supplémentaire des sons externes au moyen d'un circuit anti-bruit. En général, cet affaiblissement supplémentaire est assuré aux basses et moyennes fréquences. Ce type de protecteur peut être sélectionné pour des environnements de bruit élevé dominés par les basses fréquences.

prEN 352-5:2017 (E) 4 Introduction Active noise reduction earmuffs are designed to provide additional attenuation of external sounds by means of a noise cancellation circuit. This additional attenuation is usually provided at low and mid frequencies. They may be selected for use in low frequency dominated high noise environments. The requirements of the standard are concerned pri
