Abstract

Die Erfindung gibt ein Verfahren zum Betrieb einer Hörvorrichtung und eine zugehörige Hörvorrichtung mit einem ersten und einem zweiten Mikrofon (1, 2) an, welche ein erstes und ein zweites Mikrofonsignal (R1, R2) abgeben. Das erste und des zweiten Mikrofon (1, 2) haben eine unterschiedliche Richtwirkung, beispielsweise infolge einer unterschiedlichen Abschattung durch den Körper eines Hörgeräteträgers. Das Verfahren umfasst eine Frequenzanalyse der beiden Mikrofonsignale (R1, R2) und eine Ermittlung einer frequenzabhängigen Verstärkung für ein Ausgangssignal der Hörvorrichtung, beispielweise ein Mikrofonsignal eines dritten Mikrofons (13), aus den in den Frequenzbereich transformierten beiden Mikrofonsignalen.

The invention provides a method for operating a hearing device and an associated hearing device with a first and a second microphone (1, 2), which deliver a first and a second microphone signal (R1, R2). The first and the second microphone (1, 2) have a different directivity, for example due to a different shadowing by the body of a hearing aid wearer. The method comprises a frequency analysis of the two microphone signals (R1, R2) and a determination of a frequency-dependent amplification for an output signal of the hearing device, for example a microphone signal of a third microphone (13), from the two microphone signals transformed into the frequency range.
