Hearing protectors - General requirements - Part 1: Ear-Muffs
This part of the standard specifies requirements for construction, design, performance, marking and user information for ear-muffs. In particular, it calls for the sound attenuation of the ear-muffs, measured in accordance with EN 24869-1, to be declared and to be not less than a specified minimum. This part of the standard does not deal with ear-muffs for attachment to a helmet or which are part of a helmet. 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 - Allgemeine Anforderungen - Teil 1: Kapselgehörschützer
Dieser Teil der Norm legt Anforderungen hinsichtlich Konstruktion, Gestaltung, Leistung, Kennzeichnung und Benutzerinformationen für Kapselgehörschützer fest. Im besonderen fordert sie die Angabe der durch die Kapselgehörschützer geleisteten nach EN 24869-1 gemessenen Schalldämmung, und daß die Schalldämmung einen festgelegten Mindestwert nicht unterschreiten darf. Dieser Teil der Norm befaßt sich nicht mit Kapselgehörschützern, die an Helmen befestigt werden oder die Teil eines Helmes sind. 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 générales - Partie 1: Serre-tête
La présente partie de la norme spécifie les exigences en matière de construction, de conception, de performances, et de marquage des serre-tête ainsi que les informations destinées à l'utilisateur.
Elle prescrit en particulier que l'affaiblissement acoustique des serre-tête, mesuré conformément à l'EN 24869-1.
La présente partie de la norme ne traite pas des coquilles destinées à être montées sur un casque de sécurité industriel ou intégrés à un casque.
Dans les exigences spécifiées, les exigences ergonomiques sont prises en compte, notamment l'interaction entre l'utilisateur, l'équipement et, si possible, l'environnement de travail dans lequel l'équipement est susceptible d'être utilisé (voir l'annexe ZA et l'EN 458).

Further, by requiring that the measured soundattenuation be declared, the selection of suitable hearing protectors for individual circumstances may beundertaken according to established practice.EN 352-1 deals with requirements for ear-muffs, EN 352-2 with ear-plugs, EN 352-3 with ear-muffs attached toindustrial safety helmets. EN 13819 deals with testing plans common to all types of hearing protectors covered bythis series of ENs, and is in two Parts; Part 1: Physical test methods, and Part 2: Acoustic test methods.Additional safety requirements and the associated test procedures for level-dependent ear-muffs are contained inEN 352-4, for ear-muffs with active noise reduction in prEN 352-5, for ear-muffs with audio communications in prEN352-6 and for level-dependent ear-plugs in prEN 352-7.The Parts of EN 352, other than Parts 1, 2 and 3, cover the performance of functions additional to passive hearingprotection. Hearing protectors which incorporate one or more of these functions are subject to the requirementsand tests of each of the relevant Parts of EN 352, including Parts 1, 2 or 3, as appropriate.An associated standard EN 458 covers selection, use, care and maintenance of hearing protectors.The requirements of the standard are concerned primarily with the physical and acoustic performance of the ear-muffs.The sizing requirements enable the great majority of the industrial population to be fitted satisfactorily by ”mediumsize range” ear-muffs. Populations of other sizes may be accommodated by ”small size range” or ”large size range”ear-muffs, which are required to be accompanied by information regarding the range of sizes which they aredesigned to fit.The standard also calls for the values of sound attenuation afforded by the ear-muffs (measured in accordance withEN 24869-1) in order to assist purchasers in selecting the most appropriate model of ear-muffs for their needs.Minimum values of sound attenuation are also specified.A maximum variability in insertion loss, measured objectively after a series of performance tests, is specified. Theobjective test method only facilitates the making of comparative measurements, and the insertion loss valuesobtained will differ from the measured sound attenuation values.The latter, which require the ear-muff to be tested whilst being worn by human test subjects, is regarded asproviding the reference test method for the measurement of the acoustic performance of hearing protectorsSIST EN 352-1:2003
