ABSTRACT
The purpose of this study is to evaluate the usefulness of SF ASSR (Sound-Field Auditory Steady State Response) when comparing to hearing thresholds and typical ASSR. A total of seventy-five subjects (75 ears) were participated and divided by four groups according to their hearing thresholds; 18(28 ears) for normal-hearing, 10(10 ears) for mild sensorineural hearing loss (SNHL), 13(13 ears) for moderate SNHL, 13(13 ears) for moderate-to- severe SNHL, and 11(11 ears) for severe SNHL. Results showed that there were highly significant correlations in all test frequencies (0.5, 1, 2, 4 kHz) between the pure-tone audiogram and thresholds obtained from two kinds of ASSR measurements, especially in moderate and moderate-to-severe SNHL groups. However, normal hearing and mild SNHL groups revealed no correlation among three measurements, while showing lower correlation coefficient. The pattern of results suggests that as hearing sensitivity is higher (or poor), the higher correlation among three tests were revealed.
