Abstract
A hearing aid for automatically controlling directivity is provided. The automatic directivity controlling hearing aid controls an amplification factor and delay time for each of a plurality of acoustic signals that are generated from a plurality of microphones, to thus automatically enhance directivity so that a speech sound can be strongly heard among ambient sounds that are generated in the vicinity. Therefore, even any directional voices may be heard as accurate voices by enlarging intensity of a speech sound in contrast to ambient noise.
