Abstract (en)
[origin: WO2014139499A1] The invention relates to an acoustic module for influencing, particularly reducing, sound reflections and/or sound transmissions in a space. The module is constructed as a three-dimensional hollow body, comprising at least one sheet material made of thin-walled flexurally elastic material, which is placed under bending stress by at least one additional sheet material so as to form a cavity, in such a manner that said thin-walled flexurally elastic material assumes a curved shape. The module is characterised by particularly good acoustic properties and can be produced economically.
