Abstract: A method of programming a configurable signal processing unit of a hearing aid device comprises Providing a frequency transposition algorithm in the hearing aid device where content from more than one upper-lying source frequency band is copied or moved into one and the same lower lying destination frequency band; Providing a number of frequency transposition configurations, each comprising a specific combination of source regions and a destination region; Providing a weight parameter that specifies the amount of gain applied to a lowered signal resulting from a given frequency transposition configuration; and Providing a prescription algorithm that selects an optimum frequency transposition configuration for an ear of a user taking an audiogram for the ear in question and an amplification capability of the hearing aid device in question into account. A purpose of the disclosure is to provide an improved audibility of high frequency sound for users with severe-to-profound hearing losses.
