    • PROBLEM TO BE SOLVED: To provide a device capable of correcting audibility objectively with good reproducibility.SOLUTION: An audibility correction device includes: a sound source 18 which outputs reference voice signals of a plurality of frequencies in order; an amplifier 14 which amplifies the reference voice signals; a loudspeaker 16 which outputs the reference voice signals amplified by the amplifier 14; an information input device 24 through which a user can input a timing of change from a state in which a reference voice cannot be heard to a state in which the signal changes can be heard or from the state in which the reference voice signal can be heard to the state in which the reference voice signal cannot be heard for each of the plurality of frequencies; and a CPU 22 which stores the gain of the amplifier 14 in the timing input through the information input device 24 for each of the plurality of frequencies, and corrects predetermined ideal frequency characteristics on the basis of the stored gain. A programmable equalizer 12 is so adjusted as to obtain the corrected ideal frequency characteristics.
    • 要解决的问题:提供能够以良好的再现性客观地校正可听性的装置。解决方案:声音校正装置包括:声源18,依次输出多个频率的参考声音信号; 放大参考语音信号的放大器14; 扬声器16,其输出由放大器14放大的参考声音信号; 用户可以通过该信息输入装置24从可以听到参考语音的状态到可以听到参考语音的状态到可以听到信号改变的状态或从可以听到参考语音信号的状态输入改变的定时 到不能为多个频率中的每一个听到参考语音信号的状态; 以及CPU22,其通过信息输入装置24对于多个频率中的每一个存储放大器14的增益的定时,并且基于存储的增益来校正预定的理想频率特性。 对可编程均衡器12进行如此调整,以获得经校正的理想频率特性。
