Abstract (en)
[origin: US2019373379A1] In a method that reduces the occurrence of acoustic feedback in a hearing device, a first wearing situation is created that determines a positioning of the hearing device relative to the wearer. For the first wearing situation, a first usage situation is created being a body movement of the wearer of the hearing device and/or a relative position of an external object relative to the body of the wearer. A first number of frequency-resolved curves of a feedback tendency of the hearing device are determined for the first use situation. A first criticality measure is ascertained based on the frequency-resolved curve for the first use situation that contains information on a frequency range that is critical with respect to an occurrence of acoustic feedback and a corresponding relative probability of acoustic feedback, and a target is established for adapting a hearing device parameter based on the first criticality measure.
