    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.

    Abstract: An apparatus for determining cochlear dead region comprising a sound generation unit, an output transducer, and a control unit. The control unit causes the sound generation unit to provide a first electrical sound signal representing a first frequency band adjacent to a frequency region of interest, with a first bandwidth, a first sound pressure level and a first subsequent electrical sound signal representing a first subsequent frequency band comprising the frequency region of interest with a first subsequent bandwidth, a first subsequent sound pressure level, and a first subsequent time delay to the first electrical sound signal. In response, the output transducer generates a first output sound and a first subsequent output sound with the first subsequent time delay. A user compares the first output and first subsequent output sounds and decides, whether he hears a difference between the two sounds and gives a positive or negative decision input.
