Computerized Administration and Scoring of the Dichotic Nonsense Syllable Test

Abstract

Purpose A user-friendly computer program was designed to administer the dichotic nonsense syllable test (DNST). Computer automation makes it easier for listeners to perform the response task appropriately and for audiologists to administer and accurately score the test. Method The program presents test stimuli in a user-controlled, self-paced sequence; provides an easy-to-use client interface to collect listener responses; verifies that appropriate responses are recorded before proceeding with the test; scores responses automatically; and stores the information in an electronic format that is easy to analyze and archive. Results The automated DNST protocol is described. Verification tests confirm the accuracy of stimulus sequencing, response recording, and test scoring. Conclusions Computer automation makes administering the DNST easier, ensures the accuracy of test scoring, and simplifies the analysis and archiving of results. These refinements may make the DNST more useful to clinicians. Further research is required to establish normative data for this version of the DNST.
