CA 2589442

A hearing protector device is provided including a sound attenuating body and an electronic unit having a microphone, an amplifier, and a loudspeaker, where the electronic unit is selectively activated and, when activated, receives sound from an ambient environment, amplifies a frequency range of the received sound corresponding to a frequency range of human speech, and varies said amplification such that a total level of sound passing through the body and through the electronic unit does not exceed a maximum predetermined sound level.

L'invention concerne un dispositif protecteur d'oreilles comprenant un corps d'atténuation sonore et une unité électronique dotée d'un microphone, d'un amplificateur et d'un haut-parleur, l'unité électronique étant sélectivement activée. Lors qu'elle est activée, ladite unité électronique reçoit un son provenant d'un environnement ambiant, amplifie une gamme de fréquences du son reçu correspondant à une gamme de fréquences de la parole humaine et fait varier l'amplification de sorte que le niveau global sonore traversant le corps et l'unité électronique ne dépasse pas un niveau sonore maximum prédéterminé.
