A diagnostic test for Ménière's Disease and Cochlear Hydrops: impaired high-pass noise masking of auditory brainstem responses.

Hypothesis:Endolymphatic hydrops in patients diagnosed with Meniere's disease causes changes in the response properties of the basilar membrane that lead to impaired high-pass noise masking of auditory brainstem responses to clicks.Background:Meniere's disease is defined as the idiopathic syndrome o
