Abstract (en)
[origin: EP2469004A2] An exterior acoustic louvre (10) comprises a louvre body (12) which defines major upper and lower surfaces (22, 24) and minor side surfaces (20). The louvre body (12) includes a support element (38), a sound-energy absorption element (40) supported by the support element (38), and a flexible plastics watertight element (50) for watertightly encasing the sound-energy absorption element (40). The louvre body is arranged so that the watertightly encased sound-energy absorption element (40) can receive sound energy in the directions of both the upper and lower major surfaces (22, 24) of the louvre body (12).
