Problems solved by technology

However, to date known exterior acoustic louvres including internal sound-insulating material are only open on a lower surface to absorb incident sound energy.
This is problematic, since in use any sound energy which is reflected from the lower surface of the louvre is immediately reflected by the solid upper surface of the neighbouring louvre below.

Embodiment Construction

[0011]Referring to the drawing, there is shown one embodiment of an exterior acoustic louvre 10 which comprises a louvre body 12 connectable to an exterior support system (not shown due to being widely available and therefore understood by the skilled addressee in this field). Preferably, the exterior support system includes a plurality of brackets for engaging a plurality of the said acoustic louvres 10 in spaced apart relationship. Furthermore, the brackets may locate a lateral extent of the or each said acoustic louvre 10 at an angle to a horizontal plane or a vertical plane.

[0012]The louvre body 12 includes opposing longitudinal capping elements 14, lateral end caps (not shown) for interengaging the capping elements 14, and upper and lower cover elements 16, 18 which extend between the longitudinal capping elements 14 and the lateral end caps. The capping elements 14 and the end caps define minor side surfaces 20 of the louvre body 12, whereas the cover elements 16, 18 define at...

Abstract

An exterior acoustic louvre comprises a louvre body which defines major upper and lower surfaces and minor side surfaces. The louvre body includes a support element, a sound-energy absorption element supported by the support element, and a flexible plastics watertight element which watertightly encases the sound-energy absorption element. The louvre body is arranged so that the watertightly encased sound-energy absorption element can receive sound energy in the directions of both the upper and lower major surfaces of the louvre body.

Description

[0001]This application claims priority under 35 U.S.C. 119(b) from United Kingdom Patent Application No. GB1021888.1, filed Dec. 23, 2010, for Exterior Acoustic Louvre.[0002]The present invention relates to an exterior acoustic louvre, for example, for deadening or damping sound emanating from exterior fan units.BACKGROUND OF THE INVENTION[0003]Exterior acoustic louvres are known and as mentioned above commonly used to deaden or damp noise being generated by exteriorly placed electromechanical units, such as fans, whilst also providing adequate ventilation and shielding against ambient environmental conditions, such as sun and rain.[0004]However, to date known exterior acoustic louvres including internal sound-insulating material are only open on a lower surface to absorb incident sound energy. The upper surface is fully closed by the louvre body to prevent or limit the ingress of rain and other precipitation.[0005]This is problematic, since in use any sound energy which is reflecte...
