Two approaches to assess auditory steady-state responses (ASSR) are compared under similar test conditions: a monaural single-frequency technique with a detection method based on phase coherence (AUDERA), and a binaural multiple-frequency technique using the F-test (MASTER). ASSR thresholds at four frequencies were assessed with both methods in both ears of ten normal-hearing and ten hearing-impaired adult subjects, within a test duration of one hour. The test-retest reliability and the influence of prolonging the test duration are assessed. For the total subject group the multiple-frequency technique outperforms the single-frequency technique. In hearing-impaired subjects, however, both techniques perform equally well. Hearing thresholds can be estimated with a standard error of the estimate between 7 and 12 dB dependent on frequency. About 55% of the estimates are within 5 dB of the behavioral hearing threshold, and 94% within 15 dB. Prolonging the test duration improves the performance of both techniques.
在相似测试条件下，对评估听觉稳态反应（ASSR）的两种方法进行了比较：一种是基于相位相干检测方法的单耳单频技术（AUDERA），另一种是使用F检验的双耳多频技术（MASTER）。在一小时的测试时长内，用这两种方法对10名听力正常的成年受试者和10名听力受损的成年受试者的双耳四个频率的ASSR阈值进行了评估。评估了重测信度以及延长测试时长的影响。对于整个受试者群体，多频技术优于单频技术。然而，在听力受损的受试者中，两种技术表现相当。根据频率不同，听力阈值估计的标准误差在7至12分贝之间。约55%的估计值与行为听力阈值相差在5分贝以内，94%相差在15分贝以内。延长测试时长可提高两种技术的性能。
