CPC H04R 25/505 (2013.01) [H04R 25/30 (2013.01); H04R 2225/43 (2013.01); H04R 2225/49 (2013.01)] | 27 Claims |
1. A method of personalizing one or more parameters of a processing algorithm for use in a processor of a hearing aid for a specific user, the method comprising
performing a predictive test for estimating a hearing ability of the user when listening to test signals having different characteristics;
analyzing results of said predictive test for said user and providing a hearing ability measure for said user;
selecting a specific processing algorithm comprising a directionality algorithm of said hearing aid;
selecting a cost-benefit function for said specific processing algorithm related to said user's hearing ability in dependence of said characteristics of said test signals, wherein said cost-benefit function provides a tradeoff between the benefits of directionality and the costs of directionality, wherein said directionality algorithm tends to provide a benefit to said specific user when a target signal is at a location that is relatively enhanced by beamforming and to incur costs to said specific user when attending to locations that are strongly attenuated by beamforming; and
determining, for said user, one or more personalized parameters of said specific processing algorithm in dependence of said hearing ability measure and said cost-benefit function.
