Method to produce sound-proofing panels or surfaces for interiors - involves providing panels or surfaces including inside lengthwise through holes extending for entire length of panel and separated transversely and defining cavities of desired volume

摘要

The method involves providing the panels or surfaces including inside lengthwise through holes (11) extending for the entire length of the panel and separated transversely and defining cavities of the desired volume. At least some of the lengthwise through holes communicate with the face of the panel facing towards the room (15). The noise is generated by lengthwise slits (12) extending for at least a part of the length of the panel. The sound-proofing panel or surface is obtained by coupling together several finished base elements (310), which include semi-concavities on the respective coupling faces. The semi-concavities of one finished base element is coupled with the semi-concavities of the other finished base element so as to define the lengthwise through holes (11).
