Method for operating a wireless audio signal receiver unit and system for providing hearing assistance to a user
Abstract:
There is provided a method for operating a receiver unit (12) for receiving audio signals from a remote transmission unit (10) via a wireless audio link (56), comprising: connecting an audio signal output (41) of the receiver unit (12) to an audio signal input (42) of a hearing instrument (14A, 14B) comprising means (52) located at a user's ear or in the user's ear canal for stimulating the user's hearing according to the audio signals from the receiver unit (12) and a microphone arrangement (44); measuring by means (34, 38) included in the receiver unit (12) the impedance of the audio signal input (42) of the hearing instrument (14A, 14B); and adjusting the impedance of the audio signal output (41) of the receiver unit (12) according to the measured impedance of the audio signal input (42) of the hearing instrument (14A, 14B).
Abstract(Chinese):

提供了一种用于操作用于经由无线音频链路（56）从远程传输单元（10）接收音频信号的接收机单元（12）的方法，包括：连接接收机单元（12）的音频信号输出（41） 包括位于用户耳朵或用户耳道中的用于根据来自接收器单元（12）的音频信号刺激用户听力的装置（52）的听力仪器（14A，14B）的音频信号输入端（42） ）和麦克风装置（44）; 通过包括在接收器单元（12）中的装置（34,38）测量听力仪器（14A，14B）的音频信号输入（42）的阻抗; 以及根据所述听力仪器（14A，14B）的音频信号输入（42）的所测量的阻抗来调整所述接收器单元（12）的音频信号输出（41）的阻抗。
