Abstract:
A system for forming hearing protectors, an ear cup of such a system and a hearing protector formed from such a system. The system includes a number of first ear cups and a number of second ear cups, the first and second ear cups having noise-reducing spaces of different size, and at least one electronic unit with at least one speaker. This system allows the same type of electronic unit to be used for ear cups with different degrees of noise attenuation.
