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.IN A STEREOPHONIC REPRODUCTION EQUIPMENT IN A CLOSED SPACE, WITH PREFERENCE IN A CAR, WITH MULTIPLE SPEAKERS AND AT LEAST A HEARING PLACE, WHERE THE SPEAKERS CAN BE DISTANCED EXPANDED DIFFERENTLY, THE REPRODUCTION OF THE EQUIPMENT DELAY OF AUDIO SIGNALS PROVIDED WITH SPEAKERS, WHEN DELAY TIME IS ADJUSTABLE. THROUGH THE MEASUREMENT OF THE SOUND OPERATION TIME INDIVIDUAL SPEAKERS HAVE BEEN PROVIDED AT THE HEARING PLACE, WITH WHICH THE DELAY TIME IS AUTOMATICALLY ADJUSTABLE IN SUCH WAY, THAT THE SUM OF THE SOUND DEVELOPMENT TIME AND THE DELAY TIME ADJUSTED IS THE SAME FOR ALL SPEAKERS.
