ACOUSTICALLY ABSORBING ROOM DIVIDER

摘要

A room divider (100) for dividing a room into two sub-portions (R1, R2) and for attenuating sound (S1, S2) travelling between the two sub-portions is provided. The room divider comprises hollow cylindrical elements (110) arranged periodically for dividing the room into the two sub-portions. At least some of the hollow cylindrical elements have a cylindrical shell (111) with at least one slit (112) extending in an axial direction (120) of the shell. The shell extends continuously along the perimeter of the corresponding hollow cylindrical element from one side (113) of the at least one slit to another side (114) of the at least one slit. Each of the at least one slit faces in a local elongation direction (130) of the room divider for increasing acoustic symmetry with respect to the two sub-portions. The use of destructive interference and resonance to attenuate sound allows for a less bulky/heavy acoustically absorbing room divider.

主权项

1. A room divider for dividing at least a portion of a room into two sub-portions and for attenuating sound travelling between the two sub-portions, the room divider comprising a plurality of hollow cylindrical elements arranged periodically for dividing said portion of the room into said two sub-portions,
wherein each hollow cylindrical element has a cylindrical shell comprising a slit that extends in an axial direction of the cylindrical shell, the cylindrical shell extending continuously along the perimeter of the hollow cylindrical element from one side of the slit to another side of the slit, and the slit facing in a local elongation direction of the room divider, and wherein the room divider further comprises a light source arranged to emit light out of at least one of the hollow cylindrical elements.
