True wireless stereo (TWS) earbuds have become popular and widespread in recent years, and numerous automated pure-tone audiometer applications have been developed for portable devices. However, most of these applications require specifically designed earphones to which the public may not have access. Therefore, the present study investigates the accuracy of automated pure-tone audiometry based on TWS earbuds (Honor FlyPods). The procedure for developing an automated pure-tone audiometer is reported. Calibration of the TWS earbuds was accomplished by electroacoustic measurements and establishing corrected reference equivalent threshold sound pressure levels. The developed audiometer was then compared with a clinical audiometer using 20 hearing-impaired participants. The average signed and absolute deviations between hearing thresholds measured using the two audiometers were 3.1 dB and 6.7 dB, respectively. The overall accuracy rate in determining the presence/absence of hearing loss was 81%. The results show that the proposed procedure for an automated air-conduction audiometer based on TWS earbuds is feasible, and the system gives accurate hearing level estimation using the reported calibration framework.
真正的无线立体声 (TWS) 耳机近年来变得流行和普及，并且已经为便携式设备开发了许多自动纯音听力计应用程序。然而，这些应用程序大多数都需要专门设计的耳机，而公众可能无法使用这些耳机。因此，本研究调查了基于 TWS 耳机 (荣耀 FlyPods) 的自动纯音听力计的准确性。报告了开发自动纯音听力计的过程。通过电声测量和建立校正参考等效阈声压级来完成 TWS 耳机的校准。然后使用 20 名听力受损参与者将开发的听力计与临床听力计进行比较。两种听力计测量的听力阈值的平均符号和绝对偏差分别为 3.1dB 和 6.7dB。确定听力损失存在/不存在的总体准确率为 81%。结果表明，基于 TWS 耳机的自动气导听力计的提出的程序是可行的，并且该系统使用报告的校准框架给出了准确的听力水平估计。
