Frequency transposition applications for improving spatial hearing abilities of subjects with high-frequency hearing losses

A system for configuring a frequency transposition scheme for transposing a set of received frequencies of an audio signal received by a first and a second hearing aid worn by a subject to a transposed set of frequencies, the system comprising:

• a receiver receiving at least one determined 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;
• and
• a processor configuring a subject-dependent frequency transposition process based on the determined subject-dependent parameters, the subject-dependent frequency transposition being configured so as to improve the subject's spatial hearing capabilities, wherein
• the processor further configures the first and second hearing aid to perform the configured subject-dependent frequency transposition using the same determined subject-dependent parameters in each of the first and the second hearing aid, and
• the processor synchronizes the frequency transposition across the two ears of the subject.
