The reliability of the Auditory Steady State Response (ASSR) has not been thoroughly evaluated despite its recent application as a clinical tool for threshold estimation. The purpose of this study was to examine test-retest (TR) reliability of ASSR threshold estimates in an empirical research design. The ASSR, tested using modulation frequencies approximately 80 Hz and above, was evaluated against pure tone audiometry (PTA), and the slow vertex potential (SVP, N1-P2). Sixteen normal-hearing young female adults were tested twice, one week apart. Varying degrees of sensorineural hearing loss of a notched configuration were simulated with filtered masking noise. Test-retest reliability was assessed using Pearson-product moment correlation analysis, supplemented by other post-hoc analyses. Results demonstrated moderately strong TR reliability for ASSR at 1000, 2000 and 4000 Hz (r = 0.83-0.93); however, the reliability of ASSR at 500 Hz was weaker (r = 0.75). Results suggest that ASSR-ERA is a reliable test at mid-high frequencies, at least with the configuration and degrees of simulated sensorineural hearing loss examined in this study.
尽管听觉稳态反应（ASSR）作为一种用于阈值估计的临床工具最近已得到应用，但其可靠性尚未得到全面评估。本研究的目的是在实证研究设计中检验ASSR阈值估计的重测（TR）可靠性。使用约80Hz及以上的调制频率对ASSR进行测试，并与纯音听力测定（PTA）和慢顶点电位（SVP，N1 - P2）进行对比评估。16名听力正常的年轻成年女性接受了两次测试，间隔一周。用滤波掩蔽噪声模拟不同程度的缺口型感音神经性听力损失。使用Pearson积差相关分析评估重测可靠性，并辅以其他事后分析。结果表明，ASSR在1000、2000和4000Hz时具有中等强度的TR可靠性（r = 0.83 - 0.93）；然而，ASSR在500Hz时的可靠性较弱（r = 0.75）。结果表明，至少在所研究的模拟感音神经性听力损失的配置和程度下，ASSR - ERA在中高频是一种可靠的测试。
