1. A hearing aid to be worn by a user for auditory compensation, said hearing aid comprising:

  • a first microphone which converts a sound transmitted through air to a first input signal;

    a second microphone which converts a sound transmitted through a body of the user to a second input signal;

    an intention identification unit configured to determine a threshold such that the threshold is greater when a loudness of a noise detected from the first input signal is greater;

    a hearing-aid processing control unit configured to generate control information for controlling signal processing, based on the second input signal when a correlation value between the first input signal and the second input signal is smaller than the threshold;

    a hearing-aid signal processing unit configured to generate an output signal from the first input signal according to the generated control information, when said hearing-aid processing control unit generates the control information; and

    an output unit configured to output, as a sound, the output signal generated by said hearing-aid signal processing unit.
