WHO estimated the prevalence of disabling hearing loss is 5% of the world population (430 million). People with a risk of hearing loss from noise exposure, ototoxic drugs, and comorbidities need regular hearing assessments. It is done by pure tone audiometry (PTA), requiring a skilled audiologist, special equipment, and a soundproof room. Modern technologies can help in overcoming these barriers. This study aimed to fill the lacuna by developing a new android-based application "Shravana Mitra" (Hearing companion) with features of both air conduction (AC) and bone conduction (BC) testing.
To develop, corroborate and compare smartphone application-based audiometry with PTA.
This study was done in three phases -(i) development of a mobile application, (ii) app validation in healthy individuals (iii) testing and comparison of results with PTA in individuals visiting OPD. The third phase was done as a cross-sectional observational study including 780 individuals visiting OPD of 10-60 years of age.
The mean age of the study population was 32.89 years with female preponderance (57%). In AC testing, 83% of the pure tone average of the mobile application was within 5 dB of PTA thresholds and 99% was within 10 dB and for BC testing, 81% was within 5 dB of PTA thresholds and 98% within 10 dB.
Our user-friendly mobile application- Shravana Mitra is the first Indian application available in the google play store with both AC & BC testing, multiple language options and accuracy similar to PTA. Thus, it can be used as the best hearing screening tool in camps, high-risk individuals, or any healthcare setup requiring initial hearing assessment.
世界卫生组织估计，致残性听力损失的患病率占全球人口的5%（4.3亿）。因接触噪音、使用耳毒性药物和患有合并症而有听力损失风险的人群需要定期进行听力评估。这是通过纯音听力测试（PTA）来完成的，该测试需要技术熟练的听力学家、特殊设备和隔音室。现代技术有助于克服这些障碍。本研究旨在通过开发一款具有气导（AC）和骨导（BC）测试功能的新型安卓应用程序“Shravana Mitra”（听力助手）来填补这一空白。
开发、验证并比较基于智能手机应用程序的听力测试与纯音听力测试。
本研究分三个阶段进行——（i）开发移动应用程序，（ii）在健康个体中对应用程序进行验证，（iii）在门诊就诊的个体中测试结果并与纯音听力测试进行比较。第三阶段作为一项横断面观察性研究，纳入了780名年龄在10至60岁之间的门诊就诊个体。
研究人群的平均年龄为32.89岁，女性占多数（57%）。在气导测试中，移动应用程序的纯音平均值有83%在纯音听力测试阈值的5分贝范围内，99%在10分贝范围内；在骨导测试中，81%在纯音听力测试阈值的5分贝范围内，98%在10分贝范围内。
我们用户友好的移动应用程序——Shravana Mitra是谷歌应用商店中首款具备气导和骨导测试、多种语言选项且准确性与纯音听力测试相似的印度应用程序。因此，它可作为营地、高危个体或任何需要初步听力评估的医疗保健机构中最佳的听力筛查工具。
