Abstract

LA INVENCION SE REFIERE A UN PANEL DE INSONORIZACION QUE COMPRENDE UN ALMA DE NIDO DE ABEJA (5) INTERPUESTA EN SANDWICH ENTRE UN REVESTIMIENTO MACIZO (12) Y UN REVESTIMIENTO POROSO (13), ESTANDO LOS ALVEOLOS (6) DEL NIDO DE ABEJA (5) DIVIDIDAS EN EL SENTIDO DEL ESPESOR (5A) EN AL MENOS DOS CAVIDADES RESONANTES (11) POR AL MENOS UN TABIQUE (8) ATRAVESADO POR AMBAS PARTES DE LOS PASOS (14). TAL PANEL DE INSONORIZACION SE CARACTERIZA PORQUE LOS TABIQUES (8) ESTAN CONSTITUIDOS POR MICROBOLAS (15) HUECAS CON PAREDES POROSAS UNIDAS ENTRE SI Y CON LAS PAREDES (7) DEL NIDO DE ABEJA (5) POR SUS PUNTOS DE CONTACTO (16, 17). TAL PANEL DE INSONORIZACION SE COMBINA CON PRESTACIONES ELEVADAS EN TERMINOS DE LINEALIDAD EN FUNCION DEL NIVEL SONORO DE EXCITACION, DE BANDA DE ATENUACION, DE ENVERGADURA Y DE RESISTENCIA MECANICA.
