Abstract
A feedback threshold in a hearing device is determined by feeding an input signal to the hearing device while it is inserted in an ear canal of a user. The input signal results in a higher amplification than a supposed, that is, not yet known, feedback threshold. An amplification in the forward path of the device is measured. The feedback threshold is equal to the measured amplification.
