Hearing impairment is often associated with damage to the hair cells in the cochlea. Complete loss of inner hair cells over a certain region of the cochlea is called a "dead region". This region can be defined in terms of the range of characteristic frequencies of the inner hair cells and/or neurons immediately adjacent to the dead region. It is difficult to diagnose dead regions taking into account audiograms only. Up to now two different methods of dead regions diagnosis have been developed: measurements of psychophysical tuning curves (PTCs) (time consuming but very accurate) and the threshold-equalising noise (TEN) method (fast but sometimes giving ambiguous results). A third method, which measures PTCs by means of a noise band whose central frequency changes gradually over a certain region, is proposed in this paper. The method is a compromise between PTCs and TEN method. The method is as fast as the TEN method is and is almost as accurate as PTCs.
