Hearing protectors - Safety requirements and testing - Part 4: Level-dependent ear-muffs
This part of the Standard is concerned with ear-muffs whose acoustic performance may be regarded as being level-dependent, including those fitted with electronic sound restoration circuits and/or noise cancellation systems. 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-ear 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).

Introduction
Level-dependent ear-muffs are designed to provide restoration of external sounds, while
providing attenuation of sounds at high levels. They may be selected for use in intermittent or
impulsive noise environments and where external warning sounds are required to be heard. This
Standard is concerned with those ear-muffs having an electronic sound restoration circuit.
This part of the Standard is a specification intended for type approval purposes, for which four
sets of specimen ear-muffs are tested.
The requirements and tests of the standard are concerned primarily with the level-dependent
performance of the ear-muffs.
