The purpose of this study was to develop a computer program and the necessary interfacing systems which would enable a PDP/8-I digital computer to (1) control all aspects of administering pure-tone air- and bone-conduction stimuli; (2) recognize the need for masking based on unmasked auditory thresholds, determine the appropriate level of masking, and regulate the presentation of the masker to the nontest ear; (3) analyze the subject’s responses to the above procedures in terms of threshold-determination criteria; and (4) present the obtained thresholds in audiogram format at the conclusion of the computerized testing procedure. The threshold accuracy of this automated design was evaluated in terms of Pearson product-moment correlation coefficients and average deviations of differences obtained between thresholds determined by a clinical audiologist and computer-determined threshold values when each performed these audiometric test procedures on the same hypacusic subjects. The results of this study indicate that the computerized procedures used to determine pure-tone air- and bone-conduction thresholds are, in terms of the patients tested, a clinically feasible means of assessing these auditory functions.
