Formulating and evaluating audiological test protocols.

: This paper is the last in a series about audiological tests and test protocols (test batteries) designed to differentiate cochlear from retrocochlear site-of-lesion. While the first two papers dealt with individual tests, this paper is concerned with the audiological test protocol. A conceptual framework is presented for formulating a test protocol, and techniques are discussed for evaluating protocol performance. Using clinical data, we evaluate the performance of the traditional audiological test battery and make recommendations for the clinical use of audiological test protocols.
