Experimental Study on Auditory Tracking Performances

Abstract

Air conduction and bone conduction andiometric hearing tests are in general use. However, these screening tests have some shortcomings. They are greatly influenced by background noise and so need a sound proof room. Also, the auditory information on hearing loss is sometimes hindered by patients intentional lying or by a mistake in hearing. To overcome these problems, an apparatus that pursues tracks of auditory pitch stimulus through headphones in a special frequency range with hearing sound pressure has been developed. The pursuit tracking performances of auditory pitch and hearing loss values are highly mutually correlated at IKHZ and 4KHZ Stimulus frequency ranges. In this paper it is thown that the pursuit tracking of auditory pitch was effective as a screening test to distinguish hearing loss under noisy conditions.
