BACKGROUND
Tympanometry is used as part of a battery of tests for screening of middle ear function and may help diagnose middle ear disorders, but remains available only on expensive test equipment.
METHODS
We report a low-cost smartphone-based tympanometer system that consists of a lightweight and portable attachment to vary air pressure in the ear and measure middle ear function. The smartphone displays a tympanogram and reports peak acoustic admittance in realtime. Our programmable and open-source system operates at 226 Hz and was tested on 50 pediatric patient ears in an audiology clinic in parallel with a commercial tympanometer.
RESULTS
Our study shows an average agreement of 86 ± 2% between the 100 tympanograms produced by the smartphone and commercial device when five pediatric audiologists classified them into five classes based on the Liden and Jerger classification.
CONCLUSION
Given the accessibility and prevalence of budget smartphones in developing countries, our open-source tool may help provide timely and affordable screening of middle ear disorders.
背景
鼓室导抗测试是一系列用于筛查中耳功能的测试的一部分，有助于诊断中耳疾病，但仅在昂贵的测试设备上才能进行。
方法
我们报告了一种基于低成本智能手机的鼓室导抗计系统，该系统由一个轻便、便携的附件组成，用于改变耳内气压并测量中耳功能。智能手机实时显示鼓室导抗图并报告峰值声导纳。我们的可编程开源系统工作频率为226赫兹，并在一家听力诊所对50名儿科患者的耳朵进行了测试，同时与一台商用鼓室导抗计进行了对比。
结果
当五位儿科听力学家根据利登和耶尔格分类法将智能手机和商用设备生成的100张鼓室导抗图分为五类时，我们的研究显示两者之间的平均一致性为86±2%。
结论
鉴于发展中国家预算型智能手机的可及性和普及程度，我们的开源工具可能有助于及时且经济地筛查中耳疾病。
