Abstract

Bei einem Hörhilfegerät (2; 11, 11') werden zur Reduzierung rückkopplungsbedingter Oszillationen Mikrofonsignale eines ersten Mikrofons (1; 12) und eines beabstandeten zweiten Mikrofons (4; 12') miteinander verglichen. Werden in beiden Mikrofonsignalen Oszillationen bei derselben Frequenz detektiert, so handelt es sich dabei um tonale Nutzsignale. Oszillationen, die nur in einem der Mikrofonsignale vorhanden sind, sind dagegen rückkopplungsbedingt und werden durch geeignete Maßnahmen unterdrückt.In a hearing aid device (2, 11, 11 '), microphone signals of a first microphone (1, 12) and of a spaced-apart second microphone (4, 12') are compared with one another to reduce feedback-induced oscillations. If oscillations are detected at the same frequency in both microphone signals, these are tonal useful signals. Oscillations that are present only in one of the microphone signals, however, are feedback-related and are suppressed by appropriate measures.

Das Hörgerätesystem kann aus zwei Hörhilfegeräten bestehen, wobei das erste Mikrofon im ersten Hörgerät und des zweite Mikrofon im zweiten Hörgerät angeordnet ist.

The hearing device system can consist of two hearing aid devices, wherein the first microphone is arranged in the first hearing device and the second microphone in the second hearing device.
