Resumen
El estándar para compresión de audio de alta calidad MPEG es una norma desarrollada con el fin de comprimir señales sin perder información relevante. En particular, el estándar MPEG-1 Audio Layer III se basa en el modelo Psicoacústico I. A lo largo del presente trabajo se desarrolla un sistema que explota las características de dicho modelo perceptual para simular distintos tipos de discapacidades auditivas partiendo de las curvas que representan el umbral de audición del oido en función de la frecuencia. Se realizan experimentos objetivos y subjetivos con el fin de analizar el funcionamiento del simulador con algunos tipos de deficiencias auditivas.
