AB Lesions  of  the  eighth  cranial  nerve  and  central  audiovestibular  pathways  produce  neural  hearing  loss  and  vertigo  (Table  8–3).  One  characteristic  of  neural  hearing  loss  is  deterioration  of  speech  discrimination  out  of  proportion  to  the  decrease  in  pure  tone  thresholds.  Another  is  auditory  adaptation,  wherein  a  steady  tone  appears  to  the  listener  to  decay  and  eventually  disappear.  Auditory  evoked  responses  are  useful  in  distinguishing  cochlear  from  neural  losses  and  may  give  insight  into  the  site  of  lesion  within  the  central  pathways.
