Title:
HEARING ASSISTANCE SYSTEM AND METHOD
Document Type and Number:
WIPO Patent Application WO/2011/015675
Kind Code:
A3
Abstract:
The invention relates to a system for providing hearing assistance to a user (13), comprising at least one audio signal transmission unit (10A, 10B, 10C) comprising an audio signal source (17) and means for transmitting audio signals (19A, 19C, 19C) from the audio signal source via a wireless RF link (12); a left ear receiver unit (14B) and a right ear receiver unit (14A), wherein each receiver unit is connected to or comprises means (60, 68) for stimulating the user's hearing and comprises means (46, 48) for receiving an RF signal from the transmission unit(s) via the wireless RF link, and means (70) for measuring at least one parameter of the RF signal as received from the transmission unit(s) at the respective receiver unit in order to create left ear RF signal measurement data and right ear RF signal measurement data, respectively; means (40, 140) for estimating the angular localization of each transmission unit by comparing, for each transmission unit, the left ear RF signal measurement data and the right ear RF signal measurement data, and means (38, 138) for processing the audio signals received from the transmission unit(s) via the wireless RF link by distributing the audio signals onto a left ear channel to be supplied via the left ear receiver unit to the left ear stimulating means and a right ear channel to be supplied via the right ear receiver unit to the right ear stimulating means 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.
