Method of operating a hearing instrument based on an estimation of present cognitive load of a user and a hearing aid system
First Claim
1. A hearing aid system for obtaining an ambulatory electroencephalogram, EEG, comprising two hearing instruments and two or more electric terminals in the surface of a hearing instrument shell of the hearing instruments where the shell contacts the skin inside or outside the ear canal of a user;
- the hearing instruments comprising;
an input transducer for converting an input sound to en electric input signal, a signal processing unit for processing the input signal based on the obtained EEG to provide an input signal according to a user'"'"'s needs and providing a processed output signal, and an output transducer for converting the processed output signal to an output sound, the two hearing instruments adapted to communicate EEG signals by wireless transmission of the EEG signal from one of the two hearing instruments in one ear of the user to the other of the two hearing instruments in the other ear of the user.

Abstract
A method of operating a hearing instrument for processing an input sound and to provide an output stimulus according to a user'"'"'s particular needs, and related system, computer readable medium and data processing system. An object is to provide an improved customization of a hearing instrument. The method includes the steps a) providing an estimate of the present cognitive load of the user; b) providing processing of an input signal originating from the input sound according to a user'"'"'s particular needs; and c) adapting the processing in dependence of the estimate the present cognitive load of the user. The estimate of the present cognitive load of a user is produced by in-situ direct measures of cognitive load (e.g. based on EEG-measurements, body temperature, etc.) or by an on-line cognitive model in the hearing aid system whose parameters have been preferably adjusted to fit to the individual user.
