Acoustics - Hearing protectors - Part 3: Measurement of insertion loss of ear-muff type protectors using an acoustic test fixture (ISO 4869-3:2007)

ISO 4869-3:2007 specifies a method for measuring the insertion loss of ear-muff type hearing protectors using an acoustic test fixture. The method is applicable to the investigation of production spreads of performance as part of type approval or certification procedures, and to the investigation of the change of performance with age. It is intended to ensure that ear-muff hearing protector samples submitted for subjective testing of attenuation according to ISO 4869-1 have performances typical of the type.
The method specified in ISO 4869-3:2007 is not applicable as the basic test for type approval. Performance data obtained by this method are not intended to be quoted as representing the real-ear sound attenuation of an ear-muff, nor the protection provided by the ear-muff.

Akustik -Gehörschützer - Teil 3: Messung der Schalldämmung von Kapselgehörschützern unter Verwendung einer akustischen Prüfvorrichtung (ISO 4869-3:2007)

Diese Internationale Norm legt ein Verfahren zur Messung der Schalldämmung von Kapselgehörschützern unter Verwendung einer akustischen Prüfvorrichtung fest. Das Verfahren ist anwendbar, um im Rahmen von Bauartzulassungen Produktstreuungen zu ermitteln, alterungsbedingte Veränderungen der Leistung zu untersuchen und sicherzustellen, dass Kapselgehörschützer, die für die subjektive Prüfung der Schall¬dämmung nach ISO 4869-1 vorgelegt werden, die für diesen Typ charakteristische Leistung aufweisen.
Das in dieser Norm der Reihe ISO 4869 festgelegte Verfahren ist nicht als grundlegendes Verfahren für Bauart¬prüfungen anwendbar. Es ist nicht vorgesehen, die mit diesem Verfahren ermittelten Kenndaten weder als die tatsächliche Schalldämmung des Kapselgehörschützers noch als die durch den Kapselgehörschützer bereitgestellte Schutzwirkung anzugeben.
Zum Prüfen bestimmter Kapselgehörschützer, wie zum Beispiel an Arbeitsschutzhelmen befestigten oder solchen mit anatomisch geformten Ohrkapseln oder Ohrkissen oder Kapselgehörschützern, die auf dem Ohr aufliegen, kann eine Änderung des in dieser Norm der Reihe ISO 4869 beschriebenen Verfahrens erforderlich sein.

Acoustique - Protecteurs individuels contre le bruit - Partie 3: Mesurage de l'affaiblissement acoustique des protecteurs du type serre-tête au moyen d'un montage d'essai acoustique (ISO 4869-3:2007)

L'ISO 4869-3:2007 spécifie une méthode de mesurage de l'affaiblissement acoustique des protecteurs individuels contre le bruit du type serre-tête au moyen d'un dispositif d'essai acoustique. Cette méthode peut être employée pour l'examen d'éventuelles différences de performances en cours de fabrication, lors de procédures d'homologation ou de certification, ou pour l'étude de modifications de performances dues au vieillissement. Cette méthode est également destinée à s'assurer que les échantillons de protecteurs individuels contre le bruit du type serre-tête, soumis à l'essai subjectif d'affaiblissement acoustique conformément à l'ISO 4869-1, ont les performances caractéristiques du modèle.
La méthode spécifiée dans l'ISO 4869-3:2007 n'est pas applicable comme méthode d'essai de base pour l'homologation. Les résultats de performances obtenus au moyen de cette méthode ne sont pas censés être cités comme les résultats du mesurage de l'affaiblissement d'un serre-tête sur l'oreille réelle, ni comme la protection obtenue en utilisant un serre-tête.
