This paper presents chosen aspects of developing new DSP algorithms, which can be used in devices for hearing impaired people. We have concentrated on the advanced test for the hearing loss diagnosis and on the real time directional filtering both realized using a DSP (digital signal processor). The analyzed algorithms are implemented using specially designed, experimental DSP modules.
