Abstract:
1. A sound device comprising: an audio-information output unit configured to output an audio information; an analysis unit configured to receive the audio information outputted from the audio-information output unit, and then output a sound-spectrum information of the audio information inputted thereto; an audio-division-spectrum output unit configured to receive the sound-spectrum information of the audio information, and then output an audio-division-spectrum information indicative of a sound-volume information for each critical band width of the sound-spectrum information of the audio information inputted thereto; a noise-division-spectrum output unit configured to output a noise-division-spectrum information indicative of a sound-volume information for each critical band width of a noise; and a correction unit configured to correct the audio-division-spectrum information based on the noise-division-spectrum information, and then output a correction-division-spectrum information indicative of thus corrected audio-division-spectrum information, wherein the correction unit includes: a difference computing unit configured to calculate a difference between the audio-division-spectrum information and the noise-division-spectrum information, and then output a difference information indicative of each calculation result of the difference; and a computing unit configured to receive the audio-division-spectrum information and the difference information, and then weight and add the audio-division-spectrum information and the difference information respectively inputted thereto.
