A hearing aid adapted to a specific type of voice in an acoustical environment, a method and use

The invention relates to: A hearing aid comprising a microphone for converting an ambient sound signal to an electric sound signal, a voice detector adapted to determine if a voice is present in said electric sound signal and a frequency analyzer to determine a fundamental frequency of a voice present in said electric sound signal, a signal processor adapted to process said electric sound signal - or an electric signal derived from it - in dependence of adjustable processing parameters, a memory comprising corresponding sets of processing parameters and fundamental voice frequencies, a decision unit to select and forward from the memory to the signal processor a set of processing parameters in accordance with a fundamental frequency determined by the frequency analyzer. The invention further relates to a method of adapting a hearing aid and to the use of such hearing aid. The object of the present invention is to seek to improve the perception of different voices in a given acoustical environment for a wearer of a hearing aid. This has the advantage of allowing a modification of parameters of a hearing aid program for a signal processing unit for adapting an electrical sound signal to a specific hearing profile and acoustic environment to be modified according to the type of voice present in the actual acoustic environment and to thereby optimize the perception of that voice for the wearer of the hearing aid. The invention may e.g. be useful in hearing aids that are to be used in different social situations comprising different types of voices.
