The Home Hearing Test (HHT) is an automated pure-tone threshold test that obtains an air conduction audiogram at five test frequencies. It was developed to provide increased access to hearing testing and support home telehealth programs.
Test and retest thresholds for 1000-Hz stimuli were analyzed to determine intrasubject variability from two independent data sets.
Prospective, repeated measures.
In the Veterans Affairs (VA) study, results from 26 subjects 44 to 88 years of age (mean = 65) recruited from the Nashville VA audiology clinic were analyzed. Subjects were required to have a Windows PC in the home and were self-reported to be comfortable with using computers. Two subjects had normal hearing, and 24 had hearing losses of various severities and configurations. The National Center for Rehabilitative Auditory Research (NCRAR) sample included 100 subjects (68 males; 32 females) with a complaint of hearing difficulty recruited from the local community and Veteran population. Subjects ranged in age from 32 to 87 years (mean = 63.7 years). They were tested in a quiet room at the NCRAR.
Subjects in the VA study were provided kits for installing HHT on their home computers. HHT was installed on a computer at NCRAR to test subjects in the NCRAR study. HHT obtains a five-frequency air conduction audiogram with a retest of 1000 Hz in both ears. Only the 1000-Hz test-retest results are analyzed in this report. Six statistical measures of test-retest variability are reported.
Test and retest thresholds were highly correlated in both studies (r ≥ 0.96). Test-retest differences were within ±5 dB ≥92% of the time in the two studies. Standard deviations of absolute test-retest difference were ≤3.5 dB in the two studies.
Intrasubject variability is comparable to that obtained with manual testing by audiologists in sound-treated test rooms.
家庭听力测试（HHT）是一种自动纯音阈值测试，可在五个测试频率下获得气导听力图。它的开发目的是为了提供更多的听力测试机会，并支持家庭远程医疗计划。
分析 1000Hz 刺激的测试和复测阈值，以确定来自两个独立数据集的个体内变异性。
前瞻性、重复测量。
在退伍军人事务部（VA）研究中，分析了来自纳什维尔 VA 听力学诊所的 26 名年龄在 44 至 88 岁（平均 65 岁）的受试者的结果。受试者需要家中有 Windows PC，并且能够自我报告使用计算机的舒适度。两名受试者听力正常，24 名受试者听力损失程度和类型各不相同。国家康复听觉研究中心（NCRAR）样本包括 100 名受试者（68 名男性；32 名女性），他们因听力困难从当地社区和退伍军人中招募。受试者年龄从 32 岁到 87 岁不等（平均 63.7 岁）。他们在 NCRAR 的一个安静的房间接受测试。
VA 研究中的受试者获得了在家中计算机上安装 HHT 的套件。NCRAR 中的计算机上安装了 HHT，用于测试 NCRAR 研究中的受试者。HHT 可获得 5 个频率的气导听力图，双耳复测 1000Hz。本报告仅分析了 1000Hz 的测试-复测结果。报告了 6 种测试-复测变异性的统计测量。
两项研究中的测试和复测阈值高度相关（r≥0.96）。在两项研究中，92%以上的时间内测试-复测差异在±5dB 以内。两项研究中绝对测试-复测差异的标准差均≤3.5dB。
个体内变异性与在隔音测试室中由听力学家进行的手动测试相当。
