HEARING AID SYSTEM, A HEARING AID DEVICE AND A METHOD OF OPERATING A HEARING AID SYSTEM

摘要

The application relates to a hearing aid system comprising a hearing aid device comprising a configurable signal processing unit, a programming device configured to program the configurable signal processing unit, and a communication link allowing the exchange of data between the hearing aid device and the programming device. The application further relates to a method of programming configurable signal processing unit to provide an increased speech intelligibility by frequency lowering. The hearing aid system is configured to program the configurable signal processing unit of the hearing device according the claimed method. The invention may e.g. be used in hearing aids.

主权项

1. A method of programming a configurable signal processing unit of a hearing aid device, the method comprising:
providing a frequency transposition algorithm in the hearing aid device where content from more than one upper-lying source frequency band is copied into a single lower lying destination frequency band; providing a number of frequency transposition configurations, each comprising a specific combination of source regions and a destination region for use by said frequency transposition algorithm; providing a weight parameter that specifies an amount of gain applied to a lowered signal; and providing a prescription algorithm that selects an optimum frequency transposition configuration for an ear of the user taking the audiogram for the ear in question and an amplification capability of the hearing aid device in question into account.
