Abstract :
The development of advanced hearing prosthetic aids and cochlear implants allows many hearing impaired people to receive audio signals. A multimedia catalogue of hearing impairments was developed which includes the results of audiology tests, medical description of the subjects with different types of hearing impairments and sound examples illustrating consequences of a hearing loss. Moreover, within the framework of research projects some digital signal processing applications were developed for hearing prostheses, such as a digital waveguide model of hearing aid acoustical parts and a neural network-based beamformer. Another multimedia database was created in order to facilitate the diagnosis of hearing nerve sensitivity on the basis of electrostimulation tests. Some results of the above multimedia signal processing applications are shown
