Electrocochleography or evoked cortical responses: which is preferable in diagnosis of hearing loss?

Electrocochleography and evoked cortical potentials are both used in electric response audiometry. Both of these responses have been recorded for several years so that the authors are in a position to compare them and conclude that electrocochleography is a more useful clinical tool than the evoked response. Electrocochleographic waves are much less variable; they are not affected by sleep or sedatives; they can be recorded close to threshold and their nature, sources and pathways are better known.
