Abstract:
Objective This paper is to explore the relationship between the placement of the bone oscillator and bone-conducted thresholds to ASSR stimuli in adults with normal hearing and to investigate the amplitude and the threshold differences to bone-conducted auditory steady-state responses (BC-ASSR) stimuli between single - and multiple-stimulus conditions. Methods Two groups of subjects were selected with 0. 5, 1, 2 and 4 kHz brief tones repeated at the rate of 77, 87, 93 and 101 Hz using a B-71 bone oscillator either in single- or multiple ted no significant differences between mastoid and behind-the-ear placements. The mean and standard deviations of bone-conducted behavioral thresholds to ASSR stimuli at 0.5, 1, 2 and 4 kHz were 62.6±4.8,47.1±4.8,46.8cant difference between the two conditions while the mean and standard deviations of BC-ASSR thresholds at 0.5, 1, 2 and 4 kHz were 96.7±9.7,70.3±11.6,60.6±7.4,52.8±7.2 dB re: 1μN (ppe), respectively. Conclusion The behavioral bone-conducted thresholds to ASSR stimuli with mastoid and behind-the-ear placemen yielded no significant differences. When the stimuli intensity was 50 dB nHL, the amplitudes in single-stimulus condition were significantly higher than those to multiple-stimulus condition. There were no significant differences for BC-ASSR thresholds between single- and multiple-stimulus condition.
