A hearing aid according to an embodiment of the present disclosure includes: a microphone configured to convert sound into an electric signal and output a first signal; a receiver configured to convert the third signal that is generated by performing predetermined hearing aid processing on a second signal, into sound; a first feedback removal unit having an adaptive filter configured to adaptively estimate a first transfer function of a sound feedback path from the receiver to the microphone; and a second feedback removal unit having a fixed filter configured to receive the third signal and use a fixed filter coefficient based on a second transfer function of a vibration feedback path from the receiver to the microphone. The second signal is generated by removing from the first signal, output signals from the adaptive filter and the fixed filter.
