Abstract (en)

A method of configuring a frequency transposition scheme for transposing a set of received frequencies of an audio signal received by a hearing aid worn by a subject to a transposed set of frequencies, wherein the method comprises determining at least one subject-dependent parameter indicative of the subject's ability to detect audio frequencies, and at least one subject-dependent parameter indicative of the location in frequency of one or more spectral cues, configuring a subject-dependent frequency transposition scheme based on the determined subject-dependent parameters, the subject-dependent frequency transposition scheme being configured so as to improve the subject's spatial hearing capabilities, and adapting the hearing aid to perform the configured subject-dependent frequency transposition scheme.
