The virtual hearing aid is a computer application allowing an approximate simulation of hearing aid performance. The computer application implements algorithms simulating band-pass filters, compressors and also the perceptual masking strategies for audio signal processing. Individual persons' hearing characteristics were taken into account for this purpose. The experimental part comprises verification of engineered algorithms implemented to virtual hearing prosthesis. The paper contains also results of examinations of patients aimed at verifying the applicability of the proposed signal processing strategy to the domain of hearing prostheses.
