More Information
Summary:Some totally deaf people may have hearing sensations when their auditory tract is electrically stimulated by means of electrodes inserted into external ear canals /non-invasive/. This phenomenon can be utilized for rehabilitation of the deaf. The rate of information transmission by means of such stimulation is too low to enable the deaf to understand the speech but it is sufficient for aiding lipreading. The lipreading aid must provide the deaf with information that is complementary /not supplementary/ to what he obtains by lipreading. The necessary processing of the speech signal must be determined experimentally for each deaf. A special apparatus has been designed for this purpose and preliminary measurements have been done.
