Objective:
This study was designed to compare the results of hearing tests performed using the uHear application with those of standard audiometry in Thai people in Bangkok.
Methods:
From December 2018 to November 2019, a prospective observational study was conducted involving Thai participants aged between 18 and 80 years. All participants were tested using standard audiometry and the uHear application in a soundproof booth and in a typical hearing environment.
Results:
This study included 52 participants (12 males and 40 females). The Bland-Altman plot with the Minimal Clinical Meaningful Difference of 10 dB between standard audiometry and the uHear in a soundproof booth found agreement at 2000 Hz. The uHear in a soundproof booth showed high sensitivity at all frequencies (82.5%-98.9%) and high specificity at 500 and 1000 Hz (85.7%-100%). uHear in a typical hearing environment showed high sensitivity at 4000 and 6000 Hz (97.6%) and high specificity at 500 and 1000 Hz (100%). When considering the pure-tone average, uHear in a soundproof booth showed high sensitivity (94.7%) and specificity (90.7%), whereas, in a typical hearing environment, uHear showed poor sensitivity (34%) and high specificity (100%).
Conclusion:
uHear was accurate for hearing loss screening at 2000 Hz in a soundproof booth. However, uHear in a typical hearing environment lacked accuracy. The uHear application in a soundproof booth can be used to screen hearing loss in some situations where standard audiometry is impossible.
Level Of Evidence:
II.
