Hearing aid with radio frequency identification receiver for switching a transmission characteristic
First Claim
1. A hearing aid, comprising:
- a sound receiver that receives a sound wave and generates a microphone signal representing the sound wave;
a sound generator that generates a sound depending on a power signal;
a transmission unit connected between the sound receiver and the sound generator that;
generates the power signal depending on the microphone signal, andmodifies a transmission characteristic of the transmission unit as a function of a tag signal; and
an RFID receiver connected to the transmission unit that generates the tag signal based on a radio frequency tag presented and electromagnetically detected in a detection zone,wherein the RFID receiver is configured to generate the tag signal based on one of a plurality of radio frequency tags attached to different telephones,wherein the transmission unit is configured to generate the power signal based on a transfer function and a frequency or an amplitude of the microphone signal,wherein the transfer function is selected from at least two transfer functions based on the tag signal,wherein a first transfer function is assigned to a predefined class of tag data items in the radio frequency tags,wherein a second transfer function is assigned to an individual item of tag data in the radio frequency tags, andwherein the hearing aid is configured to switch between the first transfer function for all the telephones and the second transfer function for an individual adaption to a particular type of telephone.

Abstract
The invention relates to a hearing aid with a sound receiver for generating a microphone signal representing a sound wave received and a sound generator for generating a sound depending on a power signal received. The hearing aid has a transmission unit which on the input side is connected to the sound receiver and on the output side to the sound generator and generates a power signal depending on a microphone signal received. The transmission unit modifies a transmission characteristic of the transmission unit as a function of a tag signal received. The hearing aid has a radio frequency detection device connected to the transmission unit, with a spatial detection zone where the radio frequency detection device detects, electromagnetically and in particular inductively, a radio frequency tag and, depending on the radio frequency tag, to generate a tag signal and to output this to the transmission unit.
