CEN/TC 159/WG 2 - Amplitude sensitive hearing protectors

This document is applicable to earmuffs supplemented by a safety-related audio input. The audio signal can be transmitted by electrical input or other communication like Bluetooth . It specifies requirements on construction, design, performance, marking and user information related to the inclusion of the safety-related audio input.
Earmuffs with safety-related audio input are designed to provide speech information and warning signals, while providing attenuation of external sound. They may be selected for use in a number of different environments, for example in air traffic communication, in the police forces, in the broadcasting and entertainment industries.

This document specifies supplementary acoustic test methods for hearing protectors with additional electronic functions. The purpose of these tests is to enable assessment of the hearing protector performance as specified in the appropriate product standards.

This document is applicable to entertainment audio earmuffs. It specifies requirements on construction, design, performance, marking and user information relating to the inclusion of the entertainment audio facility.
Entertainment audio earmuffs use a wired or wireless system through which audio entertainment can be relayed. They may incorporate a radio receiver set or music player for entertainment or allow audio input from external devices.
They also offer the possibility to communicate warning signals or messages. The product standards impose a limitation on the reproduced sound pressure level at the ear.
The entertainment audio signal can be transmitted by radio (broadcast or local plant programmes) or by wire or other communication like Bluetooth.

This document is applicable to entertainment audio earplugs. It specifies requirements on construction, design, performance, marking and user information relating to the inclusion of the entertainment audio facility.

Change the requirement for linearity to check the performance up to 110 dB(A) and to report the limit of linearity if found.

This European Standard is concerned with ear-muffs whose passive acoustic performance may be augmented by an audio communications facility or circuit. It specifies additional constructional, design and performance requirements, methods of test, marking requirements and user information relating to the incorporation of the audio communications facility. 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).

This part of the Standard is concerned with ear-muffs whose passive acoustic performance may be augmented by a noise cancellation electronic circuit. It specifies constructional, design and performance requirements, methods of test, marking requirements and user information. This part of the Standard does not deal with ear-muffs for attachment to a helmet or which are part of a helmet. Neither does it deal with open-air electronic earphones that are not intended to provide attenuation. 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).

This part of the Standard is concerned with entertainment audio ear-muffs. It specifies constructional and design and performance requirements, methods of test, marking requirements and user information relating to the incorporation of the entertainment audio facility.
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 [2]).
