Abstract

Cuando el sonido es reproducido, el sonido es controlado, de manera que sea escuchado en el estado óptimo para la función de escucha específica para la gente de edad avanzada. Se describe un aparato de reproducción de sonido que comprende un medio de ajuste de característica de frecuencia que ajusta las características de frecuencia de una señal de sonido de entrada, y un medio de ajuste de volumen que controla, en forma variable, el volumen cuando la señal de sonido es salida mediante sonido. El medio de ajuste de característica de frecuencia cambia una característica de frecuencia en la cual la banda de sonido que incluye una banda de voz humana es enfatizada en una característica de frecuencia en la cual las características de la ganancia de acuerdo con una frecuencia se aplanan en forma gradual con el incremento en el volumen ajustado por el medio de ajuste de volumen. Como resultado, la banda de frecuencia de la voz humana es enfatizada de manera intensa en un modo relativo para así ayudar incluso a que la gente de edad avanzada escuche la voz humana en un volumen bajo, y a medida que el volumen crece más alto, la característica de frecuencia es cambiada a una característica de frecuencia más plana con lo cual hace posible la salida para escuchar con facilidad el sonido mientras se reduce la inconveniencia provocada por el énfasis de una banda de frecuencia específica.
