Description
使用者の第一耳の中またはそばに配置するように適応され第一入力信号を提供する第一マイクロホンシステムと、前記使用者の第二耳の中またはそばに配置するように適応され第二入力信号を提供する第二マイクロホンシステムとを備えた両耳補聴器で、
前記第一入力信号および前記第二入力信号のスペクトル変調と時間変調とが監視される測定ステップ、
前記第一入力信号および第二入力信号のスペクトル変調と時間変調とが、前記各信号の音声明瞭度の評価指標を計算することによって評価される評価ステップ、
前記両耳補聴器の第一マイクロホンシステムと第二マイクロホンシステムのマイクロホンモードが、前記計算された評価指標によって選択される操作ステップ、を備え、
全方向性(OMNI)マイクロホンモードと指向性(DIR)マイクロホンモードを自動的に切換える方法によって達成される。
例えば0.7を超える状態において有利である。
したがって、リンク58は、二つのディジタル信号プロセッサー42と52が上記本発明の方法によって、両耳信号の処理を実行できるようにし、両マイクロホンシステム38と48からの情報を、前記信号処理に利用し、マイクロホンシステム38と48各々の作動状態(OMNIまたはDIR)を決定して、使用者の選択にそった最適の音声了解度を使用者に提供する。
