Abstract
The present invention relates to an ear cap intended for use as hearing, the ear cap having a sound-reflecting outer shell and a liner of sound absorption materials. The ear cap is characterized by at least one sound-reflecting and vibration-damping weight element arranged on or within the sound absorption liner to at least partly block an audio mode of vibration that would have existed in the cap in the absence of the weight element.
