Abstract

In a hearing aid (), a control device () comprises a transmission characteristic calculator (), a correction characteristic calculator (), and a correction component (). The transmission characteristic calculator () calculates an at-fitting transmission characteristic Gf (ω) on the basis of correction-use sound data and first sound data produced by collection at an ear canal microphone () of correction-use sound outputted from a receiver () during fitting. The transmission characteristic calculator () calculates an in-usage transmission characteristic Gu (ω) on the basis of correction-use sound data and third sound data produced by collection at the ear canal microphone () of correction-use sound outputted from the receiver () according to user operation after fitting. The correction characteristic calculator () calculates a correction characteristic H (ω) on the basis of the at-fitting transmission characteristic Gf (ω) and the in-usage transmission characteristic Gu (ω). The correction component () corrects input sound data that has undergone hearing aid processing by a hearing aid processor () on the basis of the correction characteristic H (ω).
