Abstract

EN UN EQUIPO PARA LA REPRODUCCION ESTEREOFONICA EN UN ESPACIO CERRADO, CON PREFERENCIA EN UN AUTOMOVIL, CON MULTIPLES ALTAVOCES Y AL MENOS UN LUGAR DE AUDICION, DONDE LOS ALTAVOCES PUEDEN SER DISTANCIADOS AMPLIAMENTE DE FORMA DIFERENTE, LA REPRODUCCION SE REALIZA CON LA AYUDA DE EQUIPOS DE RETARDO DE SEÑALES AUDIO PROVISTAS CON LOS ALTAVOCES, CUYO TIEMPO DE RETARDO ES AJUSTABLE. POR MEDIO DE LA MEDICION DEL TIEMPO DE FUNCIONAMIENTO DEL SONIDO SE HAN PREVISTO ALTAVOCES INDIVIDUALES EN EL LUGAR DE AUDICION, CON LO CUAL LOS TIEMPO DE RETARDO SON AJUSTABLE AUTOMATICAMENTE DE TAL MODO, QUE LA SUMA DEL TIEMPO DE DESARROLLO DEL SONIDO Y DEL TIEMPO DE RETARDO AJUSTADO ES IGUAL PARA TODOS LOS ALTAVOCES.
