Patent number: 9408002Abstract: In a hearing aid with a signal processor for signal processing in accordance with selected values of a set of parameters ?, a method of automatic adjustment of a set z of the signal processing parameters ?, using a set of learning parameters ? of the signal processing parameters ? is provided, wherein the method includes extracting signal features u of a signal in the hearing aid, recording a measure r of an adjustment e made by the user of the hearing aid, modifying z by the equation z=u?+r, and absorbing the user adjustment e in ? by the equation ?N=?(u,r)+?P, wherein ?N is the new values of the learning parameter set ?, ?P is the previous values of the learning parameter set ?, and ? is a function of the signal features u and the recorded adjustment measure r.Type: GrantFiled: March 28, 2013Date of Patent: August 2, 2016Assignee: GN ReSound A/SInventors: Alexander Ypma, Almer Jacob Van Den Berg, Aalbert De Vries

Patent number: 9351087Abstract: The present invention relates to a method for automatic adjustment of signal processing parameters in a hearing aid. It is based on an interactive estimation process that incorporates user feedback. The method is capable of incorporating user perception of sound reproduction, such as sound quality over time. The user may fine-tune the hearing aid using a volume-control wheel or a push-button on the hearing aid housing, which is linked to an adaptive parameter that is a projection of a relevant parameter space. For example, this new parameter could control simple volume, the number of active microphones, or a complex trade-off between noise reduction and signal distortion. By turning the “personalization wheel” in accordance with user preferences and absorbing these preferences in the model resident in the hearing aid, it is possible to absorb user preferences while the user wears the hearing aid device in the field.Type: GrantFiled: March 17, 2007Date of Patent: May 24, 2016Assignee: GN RESOUND A/SInventors: Alexander Ypma, Almer Jacob Van Den Berg, Aalbert De Vries

Patent number: 8792659Abstract: A method of adjusting a signal processing parameter for a first hearing aid and a second hearing aid forming parts of a binaural hearing aid system to be worn by a user is provided. The binaural hearing aid system comprises a user specific model representing a desired asymmetry between a first ear and a second ear of the user. The method includes detecting a request for processing a parameter change at the first hearing aid, adjusting the signal processing parameter in the first hearing aid, and adjusting a processing parameter for the second hearing aid based on the request for processing parameter change and the user specific model.Type: GrantFiled: November 4, 2008Date of Patent: July 29, 2014Assignee: GN Resound A/SInventors: Alexander Ypma, Aalbert de Vries, Joseph Renier Gerardus Maria Leenen, Job Geurts

Patent number: 7804973Abstract: An individual with a hearing loss often experiences at least two distinct problems: 1) the hearing loss itself i.e. an increase in hearing threshold level, and 2) a signal-to-noise ratio loss (SNR loss) i.e. a loss of ability to understand high level speech in noise as compared to normal hearing individuals. According to one aspect of the present invention, this problem is solved by selecting parameter values of a noise reduction algorithm or algorithms based on the individual user's SNR loss. Thereby, a degree of restoration/improvement of the SNR of noise-contaminated input signals of the hearing prosthesis has been made dependent on user specific loss data. According to another aspect of the present invention, a hearing prosthesis capable of controlling parameters of a noise reduction algorithms in dependence on the user's current listening environment as recognized and indicated by the environmental classifier has been provided.Type: GrantFiled: April 24, 2003Date of Patent: September 28, 2010Assignee: GN ReSound A/SInventors: Aalbert De Vries, Rob Anton Jurjen De Vries
