HEARING AID DEVICE AND HEARING AID METHOD

摘要

Provided are a hearing aid device and a hearing aid method that control directivity processing or amplification processing by a user's hand placement so as to match the user's intuition. A hand placement detection means (201) detects that a state in which the difference between the phases of the sound signals of a plurality of microphones (101a, 101b) is a predetermined threshold value or less continues during a predetermined period. A hearing aid process control means (202) controls, according to the detection result, a directivity sound pickup means (203) so as to become non-directive and controls the amplification characteristics of a non-linear amplification means (204).
