Abstract

The elements of the accoustic screen are transparent and are made of glass or transparent plastics pref. acrylic resin, polycarbonates, polystyrene etc. and others which are supple or rigid. The screen consists of two main anti noise units. One (A) is of reversed V shape made by moulding or extrusion to trap waves and prevent any echo backwards. These are mounted parallel, one above the other. There can also be several plates (E) of transparent plastic material behind the other modules. These acts as sound deadeners and can be fitted between two sets of the others.

Description

ECRANS ACOUSTIQUES, TRANSPARENTS, Anti-Rdbervérants, Absorbants et Décomposants les ondes sonores.ACOUSTIC, TRANSPARENT SCREENS, Anti-Rdbervérants, Absorbents and Decomposers sound waves.

Le présent n Dispositif " est composé d'4ldments Transparents " comme par exemple le verre et certaines matières plastiques. The present n Device "is composed of Transparent elements" such as for example glass and certain plastics.

I1 est constitué de n Modules n ayant une forme cintrée et horizontale : ces Modules sont superposés et forment un Ecran. I1 consists of n Modules n having a curved and horizontal shape: these Modules are superimposed and form a Screen.

Ces " Modules " ont pour fonction de par leur forme de piéger les fluides et trains d'ondes sonores venant les frapper, de les empêcher de repartir en échos, de les enfermer à l'intérieur des Modules où ces trains d'ondes sonores et autres, s'organisent en mouvements de détentes tout en s'étalant horizontalement de part et d'autre du point d'impact sut le Module. These "Modules" function by their form to trap the fluids and sound wave trains coming to strike them, to prevent them from going back into echoes, to enclose them inside the Modules where these sound wave trains and others are organized in detente movements while spreading horizontally on either side of the point of impact on the Module.

Ce double mouvement a pour effet de modifier la longueur d'onde, d'imposer un long parcours aux ondes et d'é- taler progressivement tonde en lui faisant subir une importante perte de charges par frottements. This double movement has the effect of modifying the wavelength, of imposing a long path on the waves and of spreading the mower progressively while subjecting it to a significant pressure drop by friction.

Ces pertes de charges et dislocation des ondes sont accentuées par des reliefs structurés à l'intérieur des
Modules (rep. C); en bouts intrièursds Modules, il peut également être fixés des matériaux soniquement absorbants les ondes (rep, G planche 2)
Pour compléter l'action anti-sonore des Modules, un panneau transparent (rep. E) peut être disposé derrière ceux-ci : ce panneau peut dtre composé d'une ou de plusieurs plaques parallèles ayant des épaisseurs quelconques, espacées entre elles (rep. E' planche 2).These pressure drops and wave dislocation are accentuated by reliefs structured inside the
Modules (rep. C); inside the modules, it can also be fixed with sound absorbing materials (rep, G plate 2)
To complete the anti-sound action of the Modules, a transparent panel (rep. E) can be placed behind them: this panel can be composed of one or more parallel plates having any thickness, spaced apart (rep E 'plate 2).

Les Modules montés dos à dos symétriquement permettent de constituer des Ecrans absorbants sur les deux faces de ceux-ci. Modules mounted back to back symmetrically make it possible to form absorbent screens on both sides of them.

Les Modules sont fermés en bouts.  The Modules are closed at the end.

Ils peuvent être suspendus ou montés sur des supports verticaux (rep. F. F') ou plaqués contre des parois ou plafonds. Leurs épaisseurs et dimensions ne sont pas limitatives. They can be suspended or mounted on vertical supports (ref. F. F ') or pressed against walls or ceilings. Their thicknesses and dimensions are not limiting.

A titte d'exemple, la figure nO I (Planche nO I) montre un Ecran constitué de Modules rep. A dont la forme indique le cheminement des ondes piégées et leur organisation vers une détente verticale et horizontale. As an example, figure nO I (Plate nO I) shows a Screen made up of Modules rep. A whose shape indicates the path of trapped waves and their organization towards a vertical and horizontal expansion.

Une paroi transparente forme un complément à l'action anti-sonore des Modules (rep. E planche I). A transparent wall forms a complement to the anti-noise action of the Modules (ref. E plate I).

Le plan nO 2 montre repères A-A' des Modules dos à dos symétriquement et permettant l'affaiblissement et l'absorption acoustique sur les deux faces opposées
Une cloison transparente, (repère E' plan n0 2) placée entre les Modules, complète l'action anti-sonore des Modules, quelque soit la direction d'ot arrivent les ondes : elle peut titre aussi à multi-plaques parallèles.Plan 2 shows the AA 'marks of the modules back to back symmetrically and allowing the weakening and the acoustic absorption on the two opposite sides
A transparent partition, (reference E 'plan n0 2) placed between the Modules, completes the anti-sound action of the Modules, whatever the direction from which the waves arrive: it can also be used with parallel multi-plates.

Dans le cas de fortes intensités sonores, pour augmenter l'insonorisation générale des Ecrans, des n Echeveaux n (repère G planche nO 2) de laine de verre ou autres matériaux absorbants les ondes soniques sont disposés horizontalement en partie arrière des Modules rep. A-A' : le cheminement des ondes à travers les fibres des écheveaux produit sur celles-ci une très importante perte de charge et les disloque. In the case of high sound intensities, to increase the general soundproofing of the Screens, n Skeins n (mark G plate nO 2) of glass wool or other absorbent materials the sound waves are arranged horizontally in the rear part of the Modules rep. A-A ': the path of the waves through the fibers of the skeins produces a very large pressure drop on them and dislocates them.

Les Ecrans peuvent également entre constitués de plaques ondulées suivant la même technique. Screens can also consist of corrugated sheets using the same technique.

I1 est évident qu'une des principales caractéristiques de ces Ecrans est la n TRANSPARENCE n des éléments, mais des matériaux "translucides", colorés, m*- talliques, ou quelconques, ayant des formes identiques à celles des " Modules " décrits, auraient la meme efficacité technique d'absorption et d'affaiblissement des ondes sonores et sont donc compris dans le brevet.  It is obvious that one of the main characteristics of these Screens is the n TRANSPARENCY n of the elements, but "translucent", colored, metallic, or any materials, having shapes identical to those of the "Modules" described, would have the same technical efficiency of absorption and weakening of sound waves and are therefore included in the patent.

Ces Ecrans sont destinés à absorber ou affaiblir le niveau de pression acoustique des bruits provenant de la circulation intensive toutière ou d'une voie ferrée, métro, aérodromes ou de machines industrielles ou à l'intérieur de locaux comme les Grands Marchés,
Salles et Halls d'Expositions, de Conférences, Gares,
Tunnels et voies couvertes, façades d'immeubles, balcons, rampes de dégagements, Ecoles, Hôpitaux, Dancings, etc... These screens are intended to absorb or weaken the sound pressure level of noise coming from intensive all-terrain traffic or from a railway, metro, aerodromes or industrial machines or inside premises such as large markets,
Exhibition and Conference Halls and Halls, Stations,
Covered tunnels and paths, building facades, balconies, clearance ramps, Schools, Hospitals, Dancings, etc.
