This study evaluated the use of multiple auditory steady-state responses (ASSRs) to estimate the degree and configuration of behavioral audiograms of subjects with sensorineural hearing impairments. Place specificity of the multiple-ASSR method was also assessed. Multiple amplitude-modulated (77-105 Hz) tones (500, 1000, 2000 and 4000 Hz) were simultaneously presented to one ear. The results showed that, on average, multiple-ASSR thresholds were 14 +/- 13, 8 +/- 9, 10 +/- 10 and 3 +/- 10 dB above behavioral thresholds for 500, 1000, 2000 and 4000 Hz, respectively. Behavioral and multiple-ASSR thresholds were significantly correlated (r = 0.75-0.89). There were no significant differences between behavioral and multiple-ASSR measures of the audiogram configuration. In subjects with steep-sloping > or = 30 dB/ octave) hearing losses, multiple-ASSR thresholds did not underestimate behavioral thresholds revealing good place specificity. These results indicate that the multiple-ASSR method provides good estimates of the degree and configuration of hearing in individuals with sensorineural hearing impairments.
本研究评估了使用多种听觉稳态反应（ASSR）来估计感音神经性听力障碍患者行为听阈图的程度和形态。还评估了多ASSR方法的部位特异性。将多个调幅（77 - 105赫兹）纯音（500、1000、2000和4000赫兹）同时呈现给一只耳朵。结果显示，平均而言，对于500、1000、2000和4000赫兹，多ASSR阈值分别比行为阈值高14±13、8±9、10±10和3±10分贝。行为阈值和多ASSR阈值显著相关（r = 0.75 - 0.89）。听阈图形态的行为测量和多ASSR测量之间没有显著差异。在听力损失呈陡坡型（≥30分贝/倍频程）的受试者中，多ASSR阈值并未低估行为阈值，显示出良好的部位特异性。这些结果表明，多ASSR方法能够很好地估计感音神经性听力障碍患者的听力程度和形态。
