Patent number: 8588443Abstract: The method of operating a hearing system comprising at least two devices comprises the step of establishing a common network time among said at least two devices. Said at least two devices can be provided with information on the number of network time units that passed since a time zero point of said common network time. Information on the common network time can be communicated from one device to another device. A wireless link can be used for establishing said common network time. The common network time not only allows for a precise synchronization of events within the hearing system, but also for ordering and sequencing events. A priorization of events, like tasks and actions, is enabled, based on the common network time. Doubly-received or obsolete commands can be recognized and deleted, and tasks can be scheduled.Type: GrantFiled: May 16, 2006Date of Patent: November 19, 2013Assignee: Phonak AGInventors: Raoul Glatt, Micha Knaus, Rolf Laich

Patent number: 8571242Abstract: In a digital hearing aid device (1) frequency modification is employed above a lower spectral bound and in accordance with a compression factor. The frequency modification is dynamically adjusted in dependence on a sound environment analysis (10) or an end-user input (30), by modifying the frequency modification parameters such as a lower spectral bound and a compression factor. The adjustment can be based on an interpolation between predefined parameters. In certain sound environments, such as loud noise, own-voice and telephone conversations, frequency modification is reduced or switched off. The proposed solutions have the advantage that the occurrence of disturbing noise and of distortions of harmonic relationships at the end-user's ear is reduced and signal processing resources as well as battery resources are saved.Type: GrantFiled: May 30, 2008Date of Patent: October 29, 2013Assignee: Phonak AGInventors: Herbert Bächler, Raoul Glatt
