Abstract
A method and a hearing device for cancelling or preventing feedback are disclosed. The hearing device comprises a microphone (), a transfer function () and a receiver (), wherein the transfer function () defines relation between an input signal () of the hearing device and an output signal () of the hearing device. The method according to the present invention comprises the steps of estimating an external transfer function () of an external feedback path () defined by sound traveling from the receiver () to the microphone (), estimating the input signal (') having no feedback components of the external feedback path () using an auxiliary signal (), which does not comprise feedback components of the external feedback path (), and using the estimated input signal () for estimating the external transfer function () of the external feedback path ().
