Abstract
A hearing aid, signal processing method and program enables TV sound to be made easier for a hearing aid user to hear when wishing to watch TV, and a person's voice to be made easier to hear when wishing to converse with that person. The hearing aid includes another-person's speech detection section that detects speech of a speaker other than the wearer using detected sound source direction information, an own-speech detection result, and a TV sound detection result, and a per-sound-source frequency calculation section that calculates the frequency of each sound source using an own-speech detection result, TV sound detection result, other-speaker's speech detection result, and sound source direction information. A scene determination section determines a scene using sound source direction information and a per-sound-source frequency; and an output sound control section controls hearing of the hearing aid according to a determined scene.
