Abstract

SE COLOCAN VARIOS MICROFONOS (M1, M3) SENSIBLEMENTE EN UN MISMO PLANO (P) Y SE LES DISTRIBUYE DE FORMA SIMETRICA RESPECTO A UNA DIRECCION DE SIMETRIA (D), PERPENDICULAR A ESTE PLANO (P). SE APLICA UN DEFASAJE ENTRE LAS SEÑALES EMITIDAS RESPECTIVAMENTE DE DIFERENTES MICROFONOS (M1, M3), Y SE ADICIONAN LAS SEÑALES ASI DESFASADAS, DE TAL FORMA QUE SE ANULEN SENSIBLEMENTE LAS SEÑALES RELATIVAS A CUALQUIER ONDA SONORA PROVENIENTE EN FASE Y CON LA MISMA INTENSIDAD SOBRE CADA UNO DE LOS MICROFONOS (M1, M3). EL APARATO PUEDE ADEMAS ESTAR EQUIPADO DE UN ALTAVOZ (4), SITUADO SOBRE LA DIRECCION DE SIMETRIA (D), Y ORIENTADO SEGUN ESTA DIRECCION, EN OPOSICION A LOS MICROFONOS (M1, M3). UTILIZACION ESPECIALMENTE EN UN SISTEMA DE AUDIOCONFERENCIA.
