To evaluate the reliability and accuracy of a method for measuring pure tone air conduction thresholds in which the user adjusts test tones to threshold, using an iPad, automated instructions, and minimal supervision.
Prospective nonrandomized validation study.
University hearing research laboratories and audiology clinics.
Fifty-five adults with hearing loss in at least 1 ear ranging from mild to severe.
Automated measurement of pure tone air conduction thresholds using the following: a software-controlled adaptive method, and a user-controlled method of adjustment, both implemented on a calibrated iPad and using standard audiometry earphones.
Test-retest reliability of both methods, comparison of thresholds measured with automated techniques to thresholds measured using manual audiometry.
For both iPad methods, test-retest differences were smaller than those reported in other studies for manual audiometry. Average automated versus manual threshold differences were within the range of expected variance of manual audiometry. Subjects preferred the adjustment method.
Both iPad self-test methods yield accurate and reliable pure tone air conduction thresholds.
评估一种使用 iPad、自动化指令和最小监督，由用户调整测试音至阈值以测量纯音空气传导阈值的方法的可靠性和准确性。
前瞻性非随机验证研究。
大学听力研究实验室和听力诊所。
55 名至少 1 耳有听力损失的成年人，听力损失程度从轻度到重度不等。
使用以下方法进行纯音空气传导阈值的自动测量：软件控制的自适应方法和用户控制的调整方法，均在经过校准的 iPad 上实现，并使用标准听力计耳机。
两种方法的测试-重测可靠性，以及使用自动技术测量的阈值与使用手动听力计测量的阈值进行比较。
对于两种 iPad 方法，测试-重测差异均小于其他手动听力计研究报告的差异。平均自动与手动阈值差异在手动听力计预期变异范围内。受试者更喜欢调整方法。
两种 iPad 自测方法均可获得准确可靠的纯音空气传导阈值。
