Hearing system for estimating a feedback path of a hearing device
First Claim
1. A hearing system comprisinga programming device for programming a hearing device, the programming device comprisinga feedback path analyzer for providing an estimate of a feedback path from an output transducer to an input transducer of the hearing device,a programming interface allowing an exchange of data between the programming device and the hearing device, and whereinthe programming device —
- in a specific feedback measurement mode —
is configured to receive corresponding input and output time segments of an electric input signal or a signal derived therefrom and of a processed output signal or a signal derived therefrom, respectively, of the hearing device, via said programming interface, and whereinthe feedback path analyzer in said specific feedback measurement mode - is configured to determine said estimate of the feedback path of the hearing device based on said input and output time segments.

Abstract
A hearing system comprises a programming device comprising a) a feedback path analyzer for providing an estimate of a feedback path from an output transducer to an input transducer of a hearing device, and b) a programming interface allowing the exchange of data between the programming device and the hearing device. The programming device is configured to receive corresponding input and output time segments of an electric input signal and of a processed output signal, respectively, of the hearing device, via the programming interface, and the feedback path analyzer is configured to determine the estimate of the feedback path based on the input and output time segments. The invention may e.g. be used for the fitting of hearing devices, e.g. hearing aids, to a particular use or user.
