摘要： The present subject matter provides method and apparatus for hearing assistance devices, and more particularly to a system for evaluating hearing assistance device settings using detected sound environment. Various examples of a hearing assistance device and method using actual use and hypothetical use logs are provided. Such logs provide a dispenser or audiologist the ability to see how a device is operating with actual settings and how the device would have operated had hypothetical settings been used instead. In various examples, the system allows for collection of statistical information about actual and hypothetical use which can assist in parameter setting determinations for a specific user. The settings may be tailored to that user's commonly experienced sound environment. Wireless communications of usage logs is discussed. Additional method and apparatus can be found in the specification and as provided by the attached claims and their equivalents.

摘要： Method and apparatus for entrainment containment in digital filters using output phase modulation. Phase change is gradually introduced into the acoustic feedback canceller loop to avoid entrainment of the feedback canceller filter. Various embodiments employing different output phase modulation approaches are set forth and time and frequency domain examples are provided. Additional method and apparatus can be found in the specification and as provided by the attached claims and their equivalents.

摘要： A system providing method and apparatus to detect occurrence of an entrainment artifact and address it. The system analyzing a feedback canceller filter for certain characteristics that are associated with an entrained filter. When an entrained filter is detected, the feedback canceller filter is reset to a good filter that ideally represents the current approximate external acoustic feedback path without the characteristics of the entraining signal.
