Area of Science:

  • Audiology
  • Mobile Health Technology
  • Public Health

Background:

  • Hearing impairment has varied causes and implications, necessitating early detection through screening to prevent auditory deprivation.
  • Mobile applications offer a promising, accessible alternative for hearing assessments.

Purpose of the Study:

  • To develop a mobile application for hearing loss screening.
  • To evaluate the app's performance by comparing it against a validated screening tool.

Main Methods:

  • The Ouviu app was developed using audiological principles on the iOS platform.
  • 185 participants (ages 6-96) were evaluated using audiometry, the Ouviu app, and the HearCheck tool.

Main Results:

  • Ouviu demonstrated a sensitivity of approximately 97% for identifying hearing loss, compared to 79% for HearCheck.
  • The app had a positive predictive value of 94% and a false negative rate of 3%, outperforming HearCheck in these metrics.

Conclusions:

  • The Ouviu application is an effective hearing screening tool, particularly for mild hearing loss.
  • Its portability, ease of use, low cost, and ability to assess environmental noise offer significant advantages over traditional methods.
