Abstract [en]

The invention relates to 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. The invention further relates to a system, a computer readable medium and a data processing system. The object of the present invention is to provide an improved customization of a hearing instrument. The problem is solved in that the method comprises 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. This has the advantage that the functionality of the hearing aid system is adapted to the current mental state 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. An estimate of a user's cognitive status or cognitive load can e.g. be based on an estimate of the user's working memory capacity. The invention may e.g. be used in applications where a hearing impaired user's current mental resources are challenged.
