Description

TECHNICAL FIELD The present disclosure relates to a system for setting an audio reproduction device in an aircraft. BACKGROUND ART Patent Citation 1 discloses a reproduction device and a reproduction method in which a plurality of earphones can be used appropriately according to characteristics of each earphone. This device includes an acquisition means that acquires individual information of each connected earphone from the earphone, and a setting means for environmental setting of the device based on the individual information acquired by the acquisition means. In this way, data containing music can be reproduced with appropriate characteristics for the connected earphone. PRIOR ART CITATIONS Patent Citation Patent Citation 1: JP-A-2008-294516 SUMMARY OF INVENTION Technical Problem The present disclosure provides an audio correction means that is suitable for use in an aircraft. As for the above-mentioned means that uses individual information of the earphone, it is necessary that the earphone has the individual information for the device to identify the earphone. However, in reality, earphones distributed for use in an aircraft are required to be inexpensive, and hence it is difficult that the earphones have such individual information. The present disclosure is made in view of the above-mentioned reason, and it is an object thereof to reproduce data containing music with appropriate characteristics for each earphone when using inexpensive earphones without individual information for identification. Technical Solution An equalizer setting information setting system for an aircraft entertainment system as a part of an audio tone correction system, according to one aspect of the present disclosure, includes a storage medium interface that reads data from a recording medium that stores a plurality of data, in which first information including information about equalizer setting and second information for identifying an audio reproduction device, to which the information about equalizer setting is applied, are associated with each other; a device identifying section that acquires third information for identifying an audio reproduction device that a passenger uses; an equalizer information reading section that reads from the storage medium the first information associated with the second information corresponding to the third information; and an equalizer setting section that changes sound gain of the audio reproduction device using the information read by the equalizer information reading section. Advantageous Effects The audio tone correction system according to the present disclosure is effective for setting appropriate characteristics for each earphone that is used with an information terminal for aircraft and for each entertainment system.
