Abstract

Un panel insonorizante (1) para barreras acusticas, definido exclusivamente por una placa (2) preferentemente aunque no exclusivamente fabricada de metal, y que posee en una de las dos superficies laterales una cantidad de aletas longitudinales de quiebre de sonido (3) paralelas y enfrentadas unas con otras, cada una de ellas para quebrar el frente (F) de la onda sonora incidente; donde las aletas longitudinales de quiebre de sonido (3) poseen una seccion en forma de T y se encuentran espaciadas uniformemente a lo largo de toda la superficie lateral (2) de la placa (2) para definir una cantidad de huelgos abiertos (4) para evitar la propagacion de la onda sonora incidente; donde cada huelgo (4) posiblemente aloja un inserto (9) de material insonorizante y/o de absorcion de sonido; y la parte posterior de cada huelgo (4) posiblemente tenga piezas retenidas (11) con la concavidad selectivamente posicionada hacia adentro y hacia fuera del huelgo (4) para variar el volumen total de cada huelgo (4) en el panel insonorizante (1) conforme el requerimiento.A soundproofing panel (1) for acoustic barriers, defined exclusively by a plate (2) preferably but not exclusively made of metal, and having on one of the two lateral surfaces a quantity of longitudinal sound breaking fins (3) parallel and faced with each other, each of them to break the front (F) of the incident sound wave; where the longitudinal sound break fins (3) have a T-shaped section and are evenly spaced along the entire lateral surface (2) of the plate (2) to define a number of open strikes (4) to prevent the propagation of the incident sound wave; where each strike (4) possibly houses an insert (9) of soundproofing and / or sound absorption material; and the back of each strike (4) may have retained parts (11) with the concavity selectively positioned in and out of the strike (4) to vary the total volume of each strike (4) in the soundproofing panel (1) according to the requirement.
