Abstract (en)

[origin: EP2214424A2] The method involves determining geometry of a hearing process and/or auricle of an ear. An acoustic feedback (FB) of a hearing aid is determined from the determined geometry by comparing the determined geometry of the ear and the geometry of the hearing aid. An open loop gain (OLG) is determined from the determined acoustic feedback. The comparison is carried out by virtual projection of three-dimensional data of the geometry of the hearing aid in the determined three-dimensional geometry of the ear. An independent claim is also included for a computer program product having a computer program including a software unit for implementing a method for determining an acoustic feedback of a hearing aid when the computer program is implemented in a control unit.
