Method for operating a wireless audio signal receiver unit and system for providing hearing assistance to a user
First Claim
1. A method for operating a receiver unit for receiving audio signals from a remote transmission unit via a wireless audio link, comprising:
- connecting an audio signal output of said receiver unit to an audio signal input of a hearing instrument comprising means located at a user'"'"'s ear or in a user'"'"'s ear canal for stimulating said user'"'"'s hearing according to the audio signals from said receiver unit and a microphone arrangement;
measuring by means included in said receiver unit an impedance of said audio signal input of said hearing instrument; and
adjusting an impedance of said audio signal output of said receiver unit according to the measured impedance of said audio signal input of said hearing instrument; and
wherein said connecting step comprises electrically connecting the audio signal output of the receiver unit to the audio input of the hearing instrument via an interface which also mechanically connects the receiver unit to the hearing instrument.

17. A method for operating a receiver unit for receiving audio signals from a remote transmission unit via a wireless audio link, comprising:
-
connecting an audio signal output of said receiver unit to an audio signal input of a hearing instrument comprising means located at a user'"'"'s ear or in a user'"'"'s ear canal for stimulating said user'"'"'s hearing according to the audio signals from said receiver unit and a microphone arrangement; measuring by means included in said receiver unit an impedance of said audio signal input of said hearing instrument; adjusting an impedance of said audio signal output of said receiver unit according to the measured impedance of said audio signal input of said hearing instrument; wherein said output impedance of said receiver unit is adjusted such that a predetermined audio signal output level is achieved, and wherein said output impedance of said receiver unit is set to a pre-determined first value if connection to a high impedance audio input separate from said microphone arrangement of said hearing instrument has been detected by measuring a value of said audio input impedance less than a first threshold but equal to or higher than a second threshold. - View Dependent Claims (18, 19, 20, 21, 22, 23, 24, 25, 26, 27)
