When hearing-aid processing and predetermined-sound suppression processing are performed, in order to reduce an increase in delay of an output sound in response to an input sound greater than a case where only the hearing-aid processing is performed, a hearing aid includes: a hearing-aid processing unit (12) configured to amplify a first acoustic signal received by a microphone, according to an ability of a user to hear sound in each of frequencies, to produce a second acoustic signal; a predetermined-sound detection unit (13) configured to detect a predetermined sound included in the first acoustic signal, and to produce a control signal indicating generation timing of the predetermined sound; and a predetermined-sound suppression unit (14) configured to suppress the second acoustic signal produced in the hearing-aid processing unit at the generation timing of the predetermined-sound indicated by the control signal produced in the predetermined-sound detection unit. |
