Estimating the term…
The invention relates to a sound-attenuating device for separating off spaces in an aircraft, wherein the device (11) has a screening element (1) which is connected to a supporting means (4) such that it can be moved from a closed state to an open state, and which is designed to at least partially close an opening (12), wherein the screening element (1) comprises a first layer (6) having a sound-reflecting characteristic and a compressible second layer (7) having a sound-absorbing characteristic, which layers are arranged between a first cover layer (8) and a second cover layer (9), wherein the first layer (6), the second layer (7), the first cover layer (8) and the second cover layer (9) are stitched so as to form longitudinal seams (2), along which the screening element (1) can be folded.
A sound protection device for separating off spaces in an aircraft, wherein the device has a screening element which is connected to a supporting means such that it can be moved from a closed state to an open state, and which is designed to at least partially close an opening, wherein the screening element comprises a first layer having a sound-reflecting characteristic and a second layer, formed at least in certain sections, having, at least in certain sections, a sound-absorbing characteristic, wherein a cover layer is applied to the first or the second layer, or these are arranged between a first cover layer and a second cover layer, wherein the first layer and the second layer are stitched to the cover layer or to the first cover layer and the second cover layer so as to form longitudinal seams, along which the screening element can be folded.
