Hearing assistance suitability determining device, hearing assistance adjustment system, and hearing assistance suitability determining method

A semiconductor integrated circuit which determines a suitability of a subject for dichotic hearing assistance, said semiconductor integrated circuit comprising:

• a hearing ability information obtaining unit configured to obtain hearing ability information indicating a hearing ability of the subject for frequencies;
• a hearing ability type determining unit configured to determine, among hearing ability types each of which is defined by a tendency in a change of the hearing ability with respect to the frequencies, a hearing ability type of the hearing ability indicated by the hearing ability information;
• and
• a suitability deciding unit configured to decide, with reference to a table, the suitability of the subject for the dichotic hearing assistance based on a suitability corresponding, in the table, to the hearing ability type determined by said hearing ability type determining unit, the table showing a correspondence relationship between each of the hearing ability types and one of suitabilities for dichotic hearing assistance,
• wherein one of the hearing ability types is a high-frequency sloping type in which a hearing ability decreases as a frequency becomes higher, and
• said suitability deciding unit is configured to decide that the suitability of the subject for the dichotic hearing assistance when the hearing ability type determined by said hearing ability type determining unit is the high-frequency sloping type is to be higher than the suitability when the hearing ability type determined by said hearing ability type determining unit is not the high-frequency sloping type.

A hearing assistance suitability determining method for determining a suitability of a subject for dichotic hearing assistance, said hearing assistance suitability determining method comprising:

• obtaining hearing ability information indicating a hearing ability of the subject for frequencies;
• determining, among hearing ability types each of which is defined by a tendency in a change of the hearing ability with respect to the frequencies, a hearing ability type of the hearing ability indicated by the hearing ability information;
• and
• deciding, with reference to a table, the suitability of the subject for the dichotic hearing assistance based on a suitability corresponding, in the table, to the hearing ability type determined in said determining, the table showing a correspondence relationship between each of the hearing ability types and one of suitabilities for dichotic hearing assistance,
• wherein one of the hearing ability types is a high-frequency sloping type in which a hearing ability decreases as a frequency becomes higher, and
• in said deciding, it is decided that the suitability of the subject for the dichotic hearing assistance when the hearing ability type determined in said determining is the high-frequency sloping type is to be higher than the suitability when the hearing ability type determined in said determining is not the high-frequency sloping type.
