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 UNIFORMEWHICH HAS THE FORM OF A PANEL ABLE TO WITHSTAND THE VIBRATION OF BENDING WAVES WHICH IS CHARACTERIZED BECAUSE THE SPEED OF THE BENDING WAVES INSIDE THE PANEL VARIES IN A CONCRETE WAY WITHIN THE COINCIDENCE REGION TO PRODUCE A RANGE OF FREQUENCY FORM THAT THE ACOUSTIC COUPLING OF THE BENDING WAVES IN THE PANEL TO THE SOUND WAVES IN THE AMBIENT AIR IS PRODUCED IN A WIDER RANGE OF ANGLE AND / OR IN A WAY THAT THE COUPLING OF THE ACOUSTIC POWER TO THE ROOM AIR IS MORE UNIFORM
