1. A hearing aid which fits in an ear of a user, amplifies a sound and outputs the amplified sound, said hearing aid comprising:

  • a pick-up unit configured to pick up the sound;

    a wireless communicating unit configured to receive, from a wirelessly connected external apparatus, an instruction for outputting a searching sound;

    an amplifying unit configured to amplify the sound;

    an outputting unit configured to output the sound amplified by said amplifying unit;

    an operation switching unit configured to switch between a hearing mode and a searched mode, the hearing mode causing said amplifying unit to amplify a hearing sound, which is the sound picked up by said pick-up unit, with use of a first amplification factor, and the searched mode causing said amplifying unit to amplify the searching sound, in response to the reception of the instruction for outputting the searching sound, with use of a second amplification factor greater than the first amplification factor; and

    a storing unit configured to store a parameter indicating a frequency band suitable for a remaining hearing capability of the user,wherein, when said operation switching unit is in the searched mode, said amplifying unit extracts the frequency band indicated by the parameter from the searching sound, and amplifies the frequency band extracted from the searching sound with use of the second amplification factor.
