Abstract

EL ESPECTRO DE LOS SONIDOS SONOROS ESTA APROXIMADAMENTE A 1 KHZ O POR DEBAJO DE ELLO. EL ESPECTRO DE LOS SONIDOS INSONOROS ESTA ALREDEDOR DE 2 KHZ O POR ENCIMA DE ELLO. ES CONOCIDO QUE PARA DETERMINAR LOS COMPONENTES DE ENERGIA DE FRECUENCIA SUPERIOR E INFERIOR CONTENIDOS EN UN SONIDO O ELEMENTO DE SONIDO, SE COMPARAN DICHOS COMPONENTES DE ENERGIA Y SE USA EL RESULTADO DE LA COMPARACION PARA LLEVAR A CABO UNA DECISION SONORA E INSONORA. COMO LAS DISTRIBUCIONES RELATIVAS A LOS SEGMENTOS SONOROS E INSONOROS SE SUPERPONEN, ES FACIL QUE TENGAN LUGAR FALSAS DECISIONES. EL INVENTO SE BASA EN EL HECHO DE QUE UN CAMBIO DE UN SONIDO SONORO A UNO INSONORO O VICEVERSA, PRODUCE SIEMPRE UN CLARO DESPLAZAMIENTO DEL ESPECTRO, Y SIN DICHO CAMBIO NO EXISTE TAL DESPLAZAMIENTO. UNA MEDIDA DE UBICACION DEL CENTROIDE ESPECTRAL SE DERIVA DE LOS COMPONENTES DE ENERGIA DE ALTA Y BAJA FRECUENCIA Y SE UTILIZA PARA UNA PRIMERA DECISION. LA SEGUNDA DECISION SE REALIZA BASANDOSE EN LA DIFERENCIA ENTRE DOS MEDIDAS SUCESIVAS, Y CON ELLAS PUEDE CORREGIRSE LA PRIMER DECISION.
