Abstract
EL CUAL TIENE FORMA DE PANEL CAPAZ DE SOPORTAR LA VIBRACION DE ONDAS DE FLEXION QUE SE CARACTERIZA PORQUE LA VELOCIDAD DE LAS ONDAS DE FLEXION DENTRO DEL PANEL SE HACE VARIAR DE FORMA CONCRETA DENTRO DE LA REGION DE COINCIDENCIA PARA PRODUCIR UNA GAMA DE FRECUENCIAS DE COINCIDENCIA DE FORMA QUE EL ACOPLAMIENTO ACUSTICO DE LAS ONDAS DE FLEXION EN EL PANEL A LAS ONDAS SONORAS EN EL AIRE AMBIENTAL SE PRODUCE EN TODA UNA GAMA MAS AMPLIA DE ANGULOS Y/O DE FORMA QUE EL ACOPLAMIENTO DE LA POTENCIA ACUSTICA AL AIRE AMBIENTAL ES MAS UNIFORME
