Abstract

A LO LARGO DE UNA ESTRUCTURA EN FORMA DE ANILLO SE REPRESENTAN LOS NIVELES DE SONIDO (EL2) EN DIFERENTES LUGARES DE MEDICION (XI) EN UN PRIMER DIAGRAMA DE BARRAS Y EN UN SEGUNDO DIAGRAMA DE BARRAS DISPUESTO AL LADO (B1,B2). A CONTINUACION SE BUSCA A PARTIR DE LA COMBINACION DE LOS DOS DIAGRAMAS DE BARRAS (B1,B2) UN SEGMENTO (A) CON UN CONJUNTO COMPLETO DE POSICIONES SENSORAS (X1), EN EL CUAL EL NIVEL MAXIMO MAS ALEJADO POSIBLE ESTE EN EL CENTRO. PARA ESTE SEGMENTO (A) SE DETERMINA A CONTINUACION CADA VEZ UNA RECTA DE COMPENSACION (G1, G2). EL PUNTO DE INTERSECCION (S) DE ESTAS DOS RECTAS DE COMPENSACION (G1,G2) SIRVE PARA LA IDENTIFICACION DE LA POSICION DE LA FUGA (XL).
