To create a hearing test useable without the involvement of a clinician or calibrated equipment, suitable for children aged 5 or older.
The tablet-based app (Sound Scouts) includes tests of speech in quiet, speech in noise and tones in noise, all embedded in game designed to maintain attention. Data were collected to intelligibility-equalize the stimuli, establish normative performance, and evaluate the sensitivity with which Sound Scouts detected known hearing problems and identified their type.
Participants were children from age 5 to 14 (394 with normal hearing, 97 with previously identified hearing loss) and 50 adults with normal hearing.
With pass-fail criteria set such that 98% of children with normal hearing passed Sound Scouts, 85% of children with hearing loss failed Sound Scouts (after exclusion of children in either group who received an inconclusive result or had incomplete results). No child with four-frequency average hearing thresholds of 30 dB HL or greater in their poorer ear passed Sound Scouts. Hearing loss type was correctly identified in only two-thirds of those cases where the algorithm attempted to identify a single type of loss.
Sound Scouts has specificity and sensitivity sufficiently high to provide hearing screening around the time children typically enter school.
创建一种无需临床医生或校准设备参与即可使用的听力测试，适用于5岁及以上儿童。
基于平板电脑的应用程序（声音探索者）包括安静环境下的言语测试、噪声环境下的言语测试和噪声环境下的音调测试，所有这些测试都嵌入到旨在保持注意力的游戏中。收集数据以使刺激的可懂度均衡，建立正常表现标准，并评估声音探索者检测已知听力问题及其类型的敏感性。
参与者为5至14岁的儿童（394名听力正常，97名先前已确诊听力损失）和50名听力正常的成年人。
设定通过/不通过标准，使得98%听力正常的儿童通过声音探索者测试，85%听力损失儿童未通过声音探索者测试（排除两组中结果不确定或结果不完整的儿童）。较差耳四频率平均听力阈值为30dB HL或更高的儿童无人通过声音探索者测试。在算法试图识别单一类型听力损失的病例中，只有三分之二正确识别了听力损失类型。
声音探索者具有足够高的特异性和敏感性，能够在儿童通常入学时提供听力筛查。
