Abstract

SE DESCRIBE UN PROCEDIMIENTO PARA LA DETERMINACION DE UNA SEÑAL DE RUIDO, ESPECIALMENTE DE LA SEÑAL DE UNA PIEZA DE UN MOTOR DE COMBUSTION QUE EMITE UN RUIDO. EN UNA PRIMERA ETAPA DEL PROCEDIMIENTO SE CAPTA MEDIANTE UN SENSOR Y SE ALMACENA UNA SEÑAL DE RUIDO GLOBAL. EN UNA SEGUNDA ETAPA DEL PROCEDIMIENTO SE RETIRA LA PIEZA QUE GENERA LA SEÑAL DE RUIDO Y SE CAPTA MEDIANTE UN SENSOR EL RUIDO DE LA FUENTE ACUSTICA RESTANTE Y SE ALMACENA, COMPARANDOSE A CONTINUACION ENTRE SI LAS DOS SEÑALES ALMACENADAS, TENIENDO EN CUENTA SU FASE, Y FORMANDO UNA DIFERENCIA VECTORIAL SE DETERMINA Y PRESENTA EL RUIDO QUE INTERESA PROCEDENTE DE LA PIEZA EMISORA DE RUIDO.
