Acoustics - Hearing protectors - Part 2: Estimation of effective A-weighted sound pressure levels when hearing protectors are worn (ISO 4869-2:2018)

This document specifies three methods (the octave-band, HML and SNR methods) of estimating the A-weighted sound pressure levels effective when hearing protectors are worn. The methods are applicable to either the sound pressure level or the equivalent continuous sound pressure level of the noise. Although primarily intended for steady noise exposures, the methods are also applicable to noises containing impulsive components. It is possible that these methods could not be suitable for use with peak sound pressure level measurements.
The octave-band, H, M, L or SNR values are suitable for establishing sound attenuation criteria for selecting or comparing hearing protectors, and/or setting minimum acceptable sound attenuation requirements.

Akustik - Gehörschützer - Teil 2: Abschätzung der beim Tragen von Gehörschützern wirksamen A-bewerteten Schalldruckpegel; Deutsche Fassung EN ISO 4869-2:2018 (ISO 4869-2:2018)

Dieses Dokument legt drei Verfahren zur Abschätzung des beim Tragen von Gehörschützern wirksamen A bewerteten Schalldruckpegels (das Oktavband , das HML  und das SNR Verfahren) fest. Die Verfahren sind entweder auf den Schalldruckpegel des Lärms oder dessen äquivalenten Dauerschalldruckpegel an-wendbar. Obwohl sie primär für die Exposition gegenüber stationären Lärms bestimmt sind, sind sie auch auf impulshaltige Geräusche anwendbar. Es ist möglich, dass diese Verfahren nicht für Messungen des Spitzenschalldruckpegels geeignet  sein könnten.
Die Oktavband , H , M , L  oder SNR-Werte sind für die Festlegung von Kriterien bezüglich der Schalldämmung für die Auswahl oder den Vergleich von Gehörschützern und/oder zur Festsetzung von Mindestanforderun¬gen an die Schalldämmung geeignet.

Acoustique - Protecteurs individuels contre le bruit - Partie 2: Estimation des niveaux de pression acoustique pondérés A en cas d'utilisation de protecteurs individuels contre le bruit (ISO 4869-2:2018)

Le présent document spécifie trois méthodes (la méthode par bande d'octave, la méthode HML et la méthode SNR) pour estimer les niveaux de pression acoustique effectifs pondérés A en cas d'utilisation de protecteurs individuels contre le bruit. Ces méthodes s'appliquent soit au niveau de pression acoustique, soit au niveau de pression acoustique continu équivalent du bruit. Bien que ces méthodes soient essentiellement prévues pour des expositions à un bruit continu, elles s'appliquent également à des bruits comportant des composantes impulsives. Il est possible que ces méthodes ne soint pas appropriées pour des mesures de niveau de pression acoustique de crête.
Les valeurs par bandes d'octave, H, M, L ou SNR conviennent pour établir des critères d'affaiblissement acoustique qui serviront à sélectionner ou à comparer les protecteurs individuels contre le bruit et/ou à établir des exigences minimales acceptables pour l'affaiblissement acoustique.

Akustika - Oprema za varovanje sluha - 2. del: Ocena efektivne A-vrednotene ravni zvočnega tlaka pri nošenju osebne varovalne opreme pred hrupom (ISO 4869-2:2018)

Ta dokument določa tri metode (oktavno metodo, metodo HML in metodo SNR) za ocenjevanje efektivne A-vrednotene ravni zvočnega tlaka pri nošenju osebne varovalne opreme pred hrupom. Metode se uporabljajo za raven zvočnega tlaka ali enakovredno neprekinjeno raven zvočnega tlaka hrupa. Čeprav so metode primarno namenjene izpostavljenosti stalnemu hrupu, se uporabljajo tudi pri hrupu z impulzivnimi komponentami. Te metode morda niso primerne za uporabo pri merjenju vršne ravni zvočnega tlaka.
Oktavne vrednosti, vrednosti H, M, L ali SNR so primerne za vzpostavljanje meril dušenja zvoka pri izbiri ali primerjavi opreme za varovanje sluha in/ali določitvi zahtev glede minimalnega sprejemljivega dušenja zvoka.
