Description
ECRANS ACOUSTIQUES, Transparents, Anti-Réverbé- rants, Absorbants et Dscomposant les ondes sonores. ACOUSTIC SCREENS, Transparent, Anti-Reverberant, Absorbent and Decomposing sound waves.
Le présent n Dispositif n est composé dtélé- ments n Transparents n comme par exemple le verre et certaines matières plastiques. The present n Device n is composed of elements n Transparent n such as for example glass and certain plastics.
Il est constitué de n Modules n ayant une forme en spirale horizontale : ces Modules sont superposés et forment un Ecran. It consists of n Modules n having a horizontal spiral shape: these Modules are superimposed and form a Screen.
Ces n Modules n ont pour fonction de par leur forme spiralée de piger les fluides et trains d'ondes sonores venant les frapper, de les empêcher de repartir en échos, de les enfermer d l'intérieur de la spirale où ces trains d'ondes sonores et autres, storganisent en mouve- ments tourbillonnaires, tout en s'étalant horizontalement de part et d'autre du point d'impact sur le Module. These n Modules n have the function of their spiral shape to pick up the fluids and sound wave trains coming to strike them, to prevent them from going back into echoes, to enclose them inside the spiral where these wave trains sound and others, organize in vortex movements, while spreading horizontally on either side of the point of impact on the Module.
Ce double mouvement a pour effet de modi- fier la longueur d'onde, d'imposer un long parcours circulaire et d'étaLer progressivement l'onde en lui faisant subir une importante perte de cares par frottements. This double movement has the effect of modifying the wavelength, imposing a long circular path and gradually spreading out the wave by subjecting it to a significant loss of edges by friction.
Ces pertes de charges et dislocation des ondes sont accentuées par des reliefs structures à l'inté- rieur des Modules (fig. 3); en bouts latéraux des
Modules, il peut également être fixes des matériaux soniquement absorbants les ondes.These pressure drops and wave dislocation are accentuated by structural reliefs inside the Modules (fig. 3); in the lateral ends of
Modules, it can also be fixed wave absorbing materials.
Pour compléter l'action anti-sonore des Modules, un panneau transparent peut titre disposé derrière ceux-ci : ce panneau peut titre composé d'une ou de plusieurs plaques parallèles ayant des épaisseurs quelconques, espacdes entre elles et des spirales. To complete the anti-sound action of the Modules, a transparent panel can title placed behind these: this panel can title composed of one or more parallel plates having any thickness, spaced between them and spirals.
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 implants sur des supports verticaux ou plaqués contre des parois ou plafonds. Leurs épaisseurs et dimensions ne sont pas limitatives. They can be suspended or implanted on vertical supports or pressed against walls or ceilings. Their thicknesses and dimensions are not limiting.
A titre d'exemple, la figure n I montre un
Ecran constitué de Modules rep. I dont la forme spirallée indique le cheminement des ondes ptdgées et leur organisation tourbillonnaire au centre de la spirale.For example, Figure n I shows a
Screen made up of Modules rep. I whose spiral shape indicates the path of ptdged waves and their vortex organization in the center of the spiral.
Le repère 2 indique une paroi double transparente et formant un complément à l'action anti-sonore des Modules. Reference 2 indicates a transparent double wall forming a complement to the anti-noise action of the Modules.
La figure n 2 montre repères I des Modules dos z dos symetriquement et permettant l'arfaiblis- sement et l'absorption acoustique sur les deux faces opposées. Figure 2 shows benchmarks I of the modules back to back symmetrically and allowing weakening and sound absorption on the two opposite faces.
Une cloison transparente, repère 3 placÉe entre les Modules, complète l'action anti-sonore des !bidules, quelque soit la direction d'où arrivent les ondes : elle peut entre aussi à multi-plaques parallèles. A transparent partition, mark 3 placed between the Modules, completes the anti-sound action of the widgets, whatever the direction from which the waves arrive: it can also be entered in parallel multi-plates.
Les Ecrans peuvent également être constitues de plaques ondulées suivant la même technique. The Screens can also be made up of corrugated sheets using the same technique.
Il est évident qu'une des principales caractéristiques de ces Ecrans est la n TRANSPARENCE n des éléments, mais des matériaux "translucides", colorés, métalliauesZ ou quelconques, ayant des formes identiques à celles des n Modules " décrits, auraient la même 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 n Modules described, would have the same technical efficiency 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 routière ou d'une voie ferrde, 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 road 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 ...
