Abstract
PARA ELIMINAR LA DISTORSION ACUSTICA PROVOCADA POR LA RESONANCIA LOCAL EN CELULAS DE NUCLEO DE PANEL, SE PROPORCIONA UN ELEMENTO RADIADOR MULTIMODO RESONANTE PARA UN ALTAVOZ EN FORMA DE PANEL, CON UN LIMITE DE FRECUENCIA SUPERIOR FUNCIONAL F SUB,MAX . EL ELEMENTO TIENE DISIPADORES Y UN NUCLEO DE BASE CELULAR. LOS REVESTIMIENTOS TIENEN UN ESPESOR H, UN MODULO DE YOUNG E, UNA RELACION DE POISSON DE V Y UNA DENSIDAD DE MATERIAL RO, Y EL NUCLEO TIENE UN TAMAÑO DE CELULA ICELL CARACTERIZADO POR EL HECHO DE QUE EL TAMAÑO DE CELULA ICELL ES INFERIOR A (I).
