Design Example

The innovation of touch-tone telephony revolutionized the telecommunications industry by replacing the traditional rotary dial with a dual-tone multi-frequency (DTMF) signaling system. This system uses a matrix-style keypad with buttons arranged in four rows and three columns, creating 12 distinct signals each assigned to a pair of frequencies. Each button press results in a simultaneous generation of two sinusoidal tones – one from a low-frequency group (697 to 941 Hz) and one from a...

    概括

    这项研究验证了用于听力测试的智能手机应用程序,发现其准确度各不相同,但在远程听力查中通常具有良好的可靠性和可用性. 需要进一步的研究来增强其临床潜力.

    科学领域:

    • 数字健康数字健康
    • 听力学 听力学是指听力学.
    • 移动健康 (mHealth) 服务提供商

    背景情况:

    • 未经治疗的听力损失会对身体,精神和社会产生重大后果.
    • 在某些地区,面对面的听力评估往往无法获得.
    • 智能手机和基于Web的应用程序提供了远程听力评估的潜力,但需要验证.

    研究的目的:

    • 评估两个智能手机应用程序 (听力测试,米米听力测试) 和一个基于网络的应用程序 (MDHearing Aid) 的性能,生态有效性和可用性.
    • 为了比较这些远程听力评估工具的准确性和可靠性与标准听力测量.

    主要方法:

    • 一项涉及60名不同程度听力损失的成年人的横截面验证研究.
    • 参与者接受了标准听力测量,随后在实验室和家中使用三个应用程序进行评估.
    • 数据分析包括灵敏度,特异性,准确性 (ICC),测试复试可靠性 (ICC) 和可用性 (MAUQ分数).

    主要成果:

    • 所有应用程序都表现出中等到良好的灵敏度和特异性.
    • 精度因频率而异,在大多数应用程序中,精度在1000Hz以上的结果中等至优异.
    • 在所有测试的应用程序中,测试-重新测试可靠性和可用性通常为中等至优异.
