PROBLEM TO BE SOLVED: To provide a multicomponent hearing aid which allows reliable data-transfer between individual components of the multicomponent hearing aid, while avoiding the disadvantages of prior art.SOLUTION: The multicomponent hearing aid is provided with circuitry means 6, 15, 26 which causes at least one interruption source 8 to 10, 13, 17 to 19, 28 to 30, 33 included in the hearing aid to transfer to a predetermined operation mode at least during data transfer. In this predetermined operation mode, an interruption signal by at least one interruption source is supplied to the receivers 3, 4, 23, 41 that participate in the data transfer, at least attenuated, as compared with that in normal mode.COPYRIGHT: (C)2009,JPO&INPIT【課題】マルチコンポーネント補聴器の個々の部品間で確実にデータ伝送を行い、その際に従来技術の欠点を回避できるようにする。【解決手段】当該の補聴器内に含まれる少なくとも1つの障害源(8~10,13,17~19,28~30,33)を少なくともデータ伝送のあいだ所定の動作モードへ移行させる回路手段(6,15,26)が設けられており、当該の所定の動作モードでは少なくとも1つの障害源による障害信号がデータ伝送に関与する受信機(3,4,23,41)へ通常動作モードに比べて少なくとも減衰されて入力される。【選択図】図3
