Problems solved by technology

Therefore, their installation is time-consuming and requires the collaboration of at least two people
This is a significant disadvantage, especially if the barrier is installed and removed in a short period of time, such as to block out the sound of railroad maintenance going on overnight

Embodiment Construction

[0047] figure 1 The main components of the sound absorbing barrier 10 of the present invention are shown. The screen 10 has a screen body 20 for absorbing noise and mounting means 30 for mounting the screen 10 to a supporting structure (not shown) such as a fence or scaffolding. The screen 10 also includes fastening means 32 for securing the screen in the rolled-up state when it is not in use.

[0048] In this example, the fastening tool 32 comprises a two-piece plastic clip having a receiver 34 attached to a strap at one end of the barrier 10 and an insert 36 attached to an adjustable strap, The adjustable strap is fixed to the barrier 10 and faces the opposite end of the barrier 10 . Other fastening means are also available, such as hook and loop fasteners, or buckles and the like. The straps of the fastening tool 32 may also act as a handle for carrying the barrier when it is rolled up. With this arrangement, the barrier 10 can remain securely rolled up when not in use,...

Abstract

A sound absorbent barrier (10) has a sound absorbent layer (40) disposed between a porous first cover (50) and a second cover (60). The barrier (10) also has a waterproof sound-permeable membrane (70) between the first cover (50) and the sound absorbent layer (40). The sound absorbent layer (40) is thus protected from damage by the first and second covers (50, 60) and water ingress is prevented by the sound-permeable membrane (70). The second cover (70) may be non-porous to reflect sound waves which have passed through the sound absorbent layer (40) back through the sound absorbent (layer 40). Alternatively, the second cover may be porous to enable absorption of sound from two directions.

Description

technical field [0001] The invention relates to a flexible sound-absorbing barrier. In particular, the present invention relates to sound absorbing barriers for sound shielding of construction sites and the like. The invention is readily adaptable to other uses, such as concerts or sporting events. Background technique [0002] Representative noise barriers for such applications include solid barriers constructed of materials such as metal, plywood, or acrylic glass to prevent the transmission of noise. These barriers tend to reflect rather than absorb sound waves. Therefore, the overall level of noise is usually not reduced. In fact, the noise level inside an enclosure constituted by a barrier may be increased by the presence of the barrier. [0003] Alternatively, the noise barrier may include sound absorbing material to reduce overall noise levels. Typically, such barriers include rock wool or fiberglass as sound-absorbing materials. Although sound absorption is eff...
