Abstract
Abstract A sound barrier and sound-absorption panel preferably of a transparent nature so as not to interfere with vision of and light for the machine or other noise-emitting device, to be shielded or enclosed by one or more of the panels. The panel is formed of transparent sound-reflecting material and sound-absorbing material so arranged relatively that the sound waves are received by the panel and deflected into the sound-absorbing material. The reflecting material and sound-absorbing material are arranged to provide one or more sound-receiving pockets or cavities each of which has an outwardly-diverging sound-reflecting wall surface which faces toward the sound-emitter. The sound-absorbing material is in the form of an outwardly-extending member so located in the pocket or cavity as to absorb sound waves which are received in the pocket or cavity and are deflected into the sound-absorbing member by the sound-reflecting wall surface.

Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
175 words
A sound-absorbent structure comprising an outer shell of high-density sound-deflecting material forming a cavity with sound-deflecting walls and a mouth adapted to open toward the sound emitter, and a body of low-density sound-absorbent material disposed within the cavity and extending outwardly relative thereto in spaced relationship to the walls of said cavity; said sound-deflecting walls having inner plane surfaces diverging at an angle less than ninety degrees from an inner vertex, said sound-absorbent body being in the form of a strip of material having opposed plane surfaces and inner and outer edges with its inner edge at the vertex between said sound-deflecting walls and with its outer edge exposed at a position substantially outwardly thereof, said sound-absorbent strip bisecting said cavity formed by said diverging sound-deflecting walls to provide pockets at each side of said strip, each of said pockets having a plane sound-deflecting surface formed by one of said sound-deflecting walls and a plane absorbing surface adjacent thereto and on said sound-absorbing strip which are disposed relatively at an angle of less than 45°.
Claim 2
Dependent Claim
175 words
A sound-absorbent structure comprising an outer shell of high-density sound-deflecting material forming a cavity with sound-deflecting walls and a mouth adapted to open toward the sound emitter, and a body of low-density sound-absorbent material disposed within the cavity and extending outwardly relative thereto in spaced relationship to the walls of said cavity; said sound-deflecting walls having inner plane surfaces diverging at an angle less than ninety degrees from an inner vertex, said sound-absorbent body being in the form of a strip of material having opposed plane surfaces and inner and outer edges with its inner edge at the vertex between said sound-deflecting walls and with its outer edge exposed at a position substantially outwardly thereof, said sound-absorbent strip bisecting said cavity formed by said diverging sound-deflecting walls to provide pockets at each side of said strip, each of said pockets having a plane sound-deflecting surface formed by one of said sound-deflecting walls and a plane absorbing surface adjacent thereto and on said sound-absorbing strip which are disposed relatively at an angle of less than 45°.
Claim 3
Dependent Claim
26 words
A sound-absorbent structure according to claim 1 in which the cavity is of varying depth throughout its length and the strip is of correspondingly varying depth.
Claim 4
Dependent Claim
19 words
A sound-absorbent structure according to claim 1 in which the sound-absorbing surface is covered by a thin protective film.
Claim 5
Dependent Claim
17 words
A sound-absorbent structure according to claim 1 in which the sound-absorbent strip has heat-absorbing material incorporated therein.
Claim 6
Dependent Claim
33 words
A sound-absorbent structure according to claim 1 in which each of said plane sound-deflecting surfaces has a recess along its outer extremity to trap sound waves and deflect them into the sound-absorbing surface.
Claim 7
Dependent Claim
64 words
A sound-absorbent structure according to claim 1 in which a pair of the pockets is formed in a cavity of substantially V-cross-section, formed by a pair of the sound-deflecting walls, said strip extending longitudinally substantially co-extensive with the sound-deflecting walls in the cavity and from the vertex thereof outwardly in the bisceting relationship to the cavity to form the two equal outwardly-opening longitudinally-extending pockets.
Claim 8
Dependent Claim
25 words
A combination sound-barrier and sound-absorbent panel formed from the structure of claim 1 including a plurality of the cavities disposed side-by-side and suitably joined together.
Claim 9
Dependent Claim
19 words
A panel according to claim 7 in which transverse wall members are provided at both ends of the cavities.
Claim 10
Dependent Claim
15 words
A panel according to claim 7 in which the sound-deflecting walls are of diophanous material.
Claim 11
Dependent Claim
26 words
A combination sound-barrier and sound-absorbent panel formed of a plurality of the structures of claim 1 assembled together with their respective cavities in side-by-side parallel relationship.
Claim 12
Dependent Claim
44 words
A panel according to claim 10 in which said sound-deflecting walls members are of rigid material and are disposed upright and one of the transverse wall members is a flat base wall so that the panel can rest thereon and form a free-standing partition.
