Abstract： Objective The purpose of this study was to edit and psychometrically equate a set of Mandarin bisyllabic word lists. Methods 964 bisyllabjc words were recorded by male talker of standard Mandarin,352 words were selected to compose 10 lists. Percentage of correct word recognition was measured for each word at four intensity levels using 20 normal hearing subjects. The order of the presentation of the lists was randomized for each subject. U-sing Statistica7.0 Performance-Intensity function for each word was plotted,slopes and thresholds of them were calculated. 242 words were chosen after that, The thresholds and slopes of these words were in Guassian distribution. These words were ligitally adjusted and included in six Mandarin bisyllabic word lists of 40 words each. Two of them were for practice, four of them for test. 36 subjects with normal hearing served in our equivalent test. The orders of the presentation of the lists were randomized far each subject and results were expressed as thresholds. Results Two-factor ANO-VA was used to compare the thresholds of the 4 lists, F=1.978,P = 0.209. Conclusion These lists were considered to be primarily equivalent with each other.
