Central deafness: fact or fiction?

Although there has been some skepticism about the existence of central hearing loss because of the absence of an acceptable tool for its evaluation, techniques are now available for its measurement. There are some excellent behavioral methods available [1]. However, with judicious use of ABR, electrocochleography, and transcranially and ipsilaterally elicited middle-ear muscle reflexes, certain forms of central dysfunction can be studied physiologically.
