Patent number: 9215535Abstract: A hearing assistance system and method for wireless RF audio signal transmission from at least one audio signal source to ear level receivers, wherein a close-to-natural hearing impression is to be achieved. At least one parameter of the RF signal as received from a transmission unit at a respective receiver unit to create left ear RF signal measurement data and right ear RF signal measurement data, respectively. The angular localization of each transmission unit is obtained by comparing, for each transmission unit, the left ear RF signal measurement data and the right ear RF signal measurement data. The audio signals are processed and distributed according to the estimated angular localization of each transmission unit in a manner so that the angular localization impression of the audio signals from each transmission unit as perceived by the user corresponds to the estimated angular localization of the respective transmission unit.Type: GrantFiled: November 24, 2010Date of Patent: December 15, 2015Assignee: Sonova AGInventors: Yves Oesch, Claude Richard, Timothee Jost, Marc Secall, Christoph Schmid, Rainer Platz, Evert Dijkstra
