Zusammenfassung:	To provide a hearing support device capable of suppressing a voice uttered by a user with a hearing support device mounted.SOLUTION: The hearing support device is configured so that a pair of microphones L, R are separately arranged on both side head parts by being fitted by a user and a pair of loudspeakers 51, 52 are positioned on both ears of the user or in the vicinity thereto. A signal processing circuit includes: a mouth directivity sound processing part; and a noise cancel part for removing a signal relatively emphasizing a voice of a sound source positioned on the mouth of the user, which is processed by the mouth directivity sound processing part, from an input signal of at least one of the microphones L, R.SELECTED DRAWING: Figure 2 【課題】聴覚サポートデバイスを装着したユーザが発した声を抑えることができる聴覚サポートデバイスを提供する。【解決手段】聴覚サポートデバイスでは、ユーザが装着することで、両側頭部に、分かれて配置される一対のマイクロフォンＬ、Ｒが位置し、ユーザの両耳又は其の近傍に、一対のスピーカ５１、５２が位置する。信号処理回路は、口元指向性音響処理部と、マイクロフォンＬ、Ｒの少なくとも一方の入力信号から、口元指向性音響処理部が処理したユーザの口元に位置する音源の音声を相対的に強調する信号を差し引くノイズキャンセル部と、を有する音響制御部を備える。【選択図】図２
