Abstract
Objective: The present study aimed to establish the test-retest reliability and validity of a tablet-based automated pure-tone screening test and a word-in-noise test as hearing screening tools for older Hong Kong Cantonese-speaking adults.
Design and study sample: It was a cross-sectional within-subject study. One hundred and thirty-two older adults participated in this study, and 112 of them completed the automated pure-tone screening test, word-in-noise test, and conventional pure-tone audiometry. Pure-tone threshold of 40 dB HL at each of the tested frequencies including 500, 1000, 2000 and 4000 Hz, obtained with conventional pure-tone audiometry was set as the pass/refer criterion, for the calculation of sensitivity and specificity of the tablet-based screening tools.
Results: The tablet-based automated pure-tone screening test yielded a sensitivity of 0.93 and specificity of 0.82, while the word-in-noise test yielded a sensitivity of 0.81 and specificity of 0.70 with the cut-off chosen as a speech reception threshold of −3.5 dB signal-to-noise ratio. Both tests require around 3 minutes to be completed on both ears.
Conclusions: The tablet-based pure-tone test and word-in-noise test are reliable and valid to be used as screening tools for hearing loss in the Hong Kong Cantonese-speaking elderly.
