Abstract:
A method of operating a hearing aid system ( 100 ) based on a classification of the current sound environment and a hearing aid system ( 100 ) for carrying out the method.

Claim (Index 1):
A method of operating a hearing aid system comprising the steps of:\n providing an electrical input signal representing an acoustical signal from an input transducer of the hearing aid system; providing a feature vector comprising vector elements that represent features extracted from the electrical input signal; providing a first multitude of sound environment base classes, wherein none of the sound environment base classes are defined by the presence of speech; processing a second multitude of feature vectors in order to determine the probability that a given sound environment base class, from said first multitude of sound environment base classes, is present in an ambient sound environment; selecting a current sound environment base class by determining the sound environment base class that provides the highest probability of being present in the ambient sound environment; determining a final sound environment class based on said selected current sound environment base class and a detection of whether speech is present in the ambient sound environment; setting at least one hearing aid system parameter in response to said determined final sound environment class; and processing the electrical input signal in accordance with said setting of said at least one hearing aid system parameter, hereby providing an output signal adapted for driving an output transducer of the hearing aid system.
