More Information
Summary:A hearing protector has two closed muffs (2) which sealingly abut against the wearer's head, so that there is formed a closed space in each muff (2) and about the user's ear. A loudspeaker (4) is disposed interiorly in the muff and has a membrane (5) whose one side is turned to face towards the user's ear, and whose opposing side is turned to face towards a dosed volume which is defined by the membrane and an enclosure. In order to improve the base reproduction in listening to music, the interior of the enclosure is, via at least one hole or one duct, in communication with the ambient surroundings outside the closed space of the muff (2). In one preferred embodiment, the enclosure comprises a capsule (7) which is integrated part of the loudspeaker (4).
