Abstract

DISPOSITIVO (1) DE APANTALLAMIENTO ACÚSTICO PARA AMORTIGUAR EL RUIDO PERTURBADOR, ESPECIALMENTE EL RUIDO QUE PROVIENE DE TRÁFICO CARRETERO, DE TRÁFICO FERROVIARIO Y SIMILARES, QUE RESUELVE PROBLEMAS TÉCNICOS DE MEJOR Y MÁS SENCILLO MANTENIMIENTO, TANTO DE LIMPIEZA COMO DE REEMPLAZO EN CASO DE ROTURA, Y DE COSTOS Y FABRICACIÓN, AL REDUCIR LA CANTIDAD DE ELEMENTOS COMPONENTES. EL DISPOSITIVO COMPRENDE UN ARMAZÓN (2),<br /> PREFERIBLEMENTE DE CONCRETO, Y UN ABSORBEDOR (3) DE RUIDOS DISPUESTO EN ÉL, PREFERIBLEMENTE MONTADO DE FORMA PLANA CONTRA EL ARMAZÓN (2), Y EN EL CUAL EL ABSORBEDOR DE RUIDOS ESTÁ CONFIGURADO COMO UN CONJUNTO (3) INTERCAMBIABLE COMPRENDIENDO UNA ESTERA ABSORBEDORA (13) DEL RUIDO, EN QUE UN FORMADOR<br /> (14) DE ESPACIO DE AIRE ESTÁ DISPUESTO DE MANERA INTEGRADA EN EL CONJUNTO (3) DETRÁS DE LA ESTERA ABSORBEDORA (13) DEL RUIDO, DE TAL FORMA QUE UN ESPACIO (15) DE AIRE SE FORMA ENTRE LA ESTERA ABSORBEDORA (13) DEL RUIDO Y EL ARMAZÓN (2); EL FORMADOR (14) DE ESPACIO DE AIRE ESTÁ DISPUESTO PARA FORMAR UN NÚMERO DE CELDAS (16) O COMPARTIMENTOS ENTRE LA ESTERA ABSORBEDORA (13) DEL RUIDO Y EL ARMAZÓN (2). ESTANDO DISPUESTAS LAS CELDAS (16) O LOS COMPARTIMENTOS PARA FORMAR VOLÚMENES DE AIRE SUSTANCIALMENTE<br /> CERRADOS; Y, LA ESTERA ABSORBEDORA (13) DEL RUIDO ESTÁ DISPUESTA PARA SER. AL MENOS EN ALGÚN GRADO, PERMEABLE AL RUIDO Y AL AIRE.<br />  ACOUSTIC SHIELDING DEVICE (1) TO DAMPEN DISTURBING NOISE, ESPECIALLY THE NOISE COMING FROM ROAD TRAFFIC, RAIL TRAFFIC AND SIMILAR, WHICH SOLVES TECHNICAL PROBLEMS OF IMPROVEMENT, MORE SIMPLY CLEANING, AS MORE SIMPLY CLEANING AND COST AND MANUFACTURING, BY REDUCING THE QUANTITY OF COMPONENT ELEMENTS. THE DEVICE INCLUDES A FRAME (2), <br /> PREFERABLY CONCRETE, AND A NOISE ABSORBER (3) DISPOSED ON IT, PREFERABLY MOUNTED FLAT AGAINST THE FRAME (2), AND IN WHICH THE NOISE ABSORBER IS CONFIGURED AS AN INTERCHANGEABLE ASSEMBLY (3) INCLUDING A NOISE ABSORBING MAT (13), IN WHICH AN AIR SPACE FORMER (14) IS INTEGRATED IN THE ASSEMBLY (3) BEHIND THE ABSORBING MAT ( 13) NOISE, IN SUCH A WAY THAT A SPACE (15) OF AIR IS FORMED BETWEEN THE NOISE ABSORBING MAT (13) AND THE FRAME (2); THE AIR SPACE FORMER (14) IS ARRANGED TO FORM A NUMBER OF CELLS (16) OR COMPARTMENTS BETWEEN THE NOISE ABSORBING MAT (13) AND THE FRAME (2). WHERE THE CELLS (16) OR THE COMPARTMENTS ARE READY TO FORM SUBSTANTIALLY CLOSED AIR VOLUMES <br />; AND, THE NOISE ABSORBING MAT (13) IS READY TO BE. AT LEAST TO SOME DEGREE, PERMEABLE TO NOISE AND AIR. <br />
