説明

Before explaining about the psychoacoustical test related recruitment phenomenon, the Equal Loudness Contours and Loudness Growth Curve are described first. It is necessary to conduct the loudness recruitment test for the differential diagnosis of cochlear impairment. In cases of unilateral moderate sensorineural hearing loss, the alternate binaural loudness balance (ABLB: Fowler) technique must be tried initially. The ABLB technique and a few problems associated with its use are described. The difference limen (DL) tests, including not only intensity DL but also frequency DL and duration DL, are explained with a review of the audiologic literature. Further, the procedure for the short increment sensitivity index (SISI) test is explained in detail. Today, the SISI test is used more frequently than the DL test clinically.<br>The procedure and evaluation of short-tone threshold audiometry are explained. Despite the apparent simplicity of hearing tests, it is clinically difficult to obtain precise values.
