EN 352-1 deals with requirements for ear-muffs, EN 352-2 with ear-plugs, EN 352-3 with ear-muffs attached to industrial safety helmets. EN 13819 parts 1 and 2 deal with testing plans common to all types of hearing protectors covered by this series of European Standards.
Additional safety requirements and the associated test procedures for level-dependent ear-muffs are contained in EN 352-4, for active noise reduction ear-muffs in EN 352-5, for ear-muffs with safety-related electrical audio input in EN 352-6 and for level-dependent ear-plugs in EN 352-7. An associated standard EN 458 [2] covers selection, use, care and maintenance of hearing protection. The particular requirement for hearing protectors in relation to their ability to reduce noise to below daily limit levels set by Directive 2003/10/EC "on the protection of workers from the risks related to exposure to noise at work" is addressed in the standard by means of a limitation of that sound pressure level effective to the ear which is generated by the entertainment audio equipment of the ear-muff. This limitation is to be tested and reported at full volume setting. The sound pressure level limit for the reproduced sound of the audio entertainment is limited to 82 dB(A). Completion of the information given on entertainment audio ear-muffs by the passive attenuation data reported within EN 352-1, which is required by this standard, enables the user to fulfil the particular requirement on daily limit levels set by Directive 2003/10/EC.
Entertainment audio ear-muffs are designed to provide not only sound attenuation to ambient sound but also to provide entertainment audio via built-in loudspeakers. The entertainment audio signal can be transmitted by radio (broadcast or local plant programmes) or by wire or other communication. The audio signal transmission is for entertainment and not for safety or work-related purposes. This part of the standard is a specification intended for type approval purposes, for which four sets of specimen ear-muffs are tested (further samples may be required for testing under EN 352-1 or EN 352-3, as appropriate).
The requirements and tests of the standard are concerned primarily with the entertainment audio performance of the ear-muffs. The standard may be applied to ear-muffs for fitting to industrial safety helmets.

EN 13819-1, Hearing protectors — Testing — Part 1: Physical test methods EN 13819-2, Hearing protectors — Testing — Part 2: Acoustic test methods EN ISO 11904-1:2002, Acoustics — Determination of sound immission from sound sources placed close to the ear — Part 1: Technique using a microphone in a real ear (MIRE technique) (ISO 11904-1:2002) 3 Terms and definitions For the purposes of this Standard, the terms and definitions given in EN 352-1:2002 or EN 352-6:2002, as appropriate, together with the following apply. 3.1 diffuse field related sound pressure level sound pressure level of a diffuse sound field which will give rise to the measured ear canal sound pressure level, when a subject is exposed to a diffuse field (EN ISO 11904-1:2002, Clause 3.6)
NOTE Ear canal sound pressure level is the equivalent continuous sound pressure level measured at the ear canal measurement position (EN ISO 11904-1:2002, Clause 3.2). Ear canal measurement position is the position in the ear canal where the sound pressure is measured (EN ISO 11904-1:2002, Clause 3.1). 3.2 entertainment audio ear-muffs ear-muffs additionally providing reproduced sound for entertainment purposes
NOTE They may be designed with an electrical audio input or with built-in broadcast receivers. Or they may be part of a complete system composed of transmitters and receiving audio ear-muffs.
