    • The object of this invention is to obtain the optimum music level by separately and independently performing the sound correction for the high-frequency range and low-frequency range according to the noise level. The invention comprises: a memory unit in which high-frequency-correction-level information, corresponding to the vehicle speed and music level, and low-frequency-correction-level information, corresponding to the low-frequency noise/music level ratio, are stored; a high-frequency-correction-level-information-acquisition unit that obtains high-frequency-correction-level information based on the vehicle speed and music level; and a low-frequency-correction-level-information-acquisition unit that obtains low-frequency-correction-level information based on the low-frequency noise/music level ratio; and it corrects the sound by a sound-quality-adjustment unit based on the high-frequency-correction-level information and low-frequency-correction-level information.
    • 本发明的目的是通过根据噪声水平独立且独立地执行高频范围和低频范围的声音校正来获得最佳音乐水平。 本发明包括:对应于低频噪声/音乐电平比率的对应于车速和音乐电平的高频校正级信息和低频校正级信息的存储单元是 储存; 高频校正级别信息获取单元,其基于车速和音乐级别获得高频校正级信息; 以及低频校正级别信息获取单元,其基于所述低频噪声/音乐电平比获得低频校正级信息; 并且其基于高频校正级信息和低频校正级信息通过声音质量调整单元来校正声音。
