Hearing

52.8K
When we hear a sound, our nervous system is detecting sound waves—pressure waves of mechanical energy traveling through a medium. The frequency of the wave is perceived as pitch, while the amplitude is perceived as loudness.

Summary

Smartphone hearing tests offer remote assessment. Mimi showed accuracy comparable to in-clinic audiometry, while uHear had inaccuracies. Patient satisfaction favored uHear, but Mimi is a viable alternative for hearing assessments.

Area of Science:

  • Audiology
  • Digital Health
  • Medical Technology

Background:

  • The COVID-19 pandemic highlighted the need for remote hearing assessment solutions.
  • Mobile applications offer a potential avenue for accessible audiometric testing.

Purpose of the Study:

  • To evaluate the accuracy of two smartphone-based hearing assessment applications, Mimi and uHear.
  • To compare the validity of mobile app hearing tests against traditional in-clinic audiometry.
  • To assess patient satisfaction with the usability of these mobile hearing test applications.

Main Methods:

  • One hundred patients underwent both mobile app (Mimi or uHear) and standard in-clinic audiometric testing.
  • Hearing thresholds from app tests were compared to gold-standard audiometry results.
  • Patient satisfaction was measured via a questionnaire assessing need fulfillment, recommendation likelihood, and repeat usage intention.

Main Results:

  • Mimi demonstrated no significant difference in average hearing levels compared to standard audiometry.
  • uHear inaccurately overestimated hearing loss at 500/1000 Hz and underestimated it at 6000 Hz.
  • Mimi exhibited higher sensitivity (0.971) and specificity (0.912) for hearing loss detection than uHear (0.914, 0.780).
  • Despite accuracy differences, uHear received higher patient satisfaction scores across all measured aspects.

Conclusions:

  • The Mimi application is a potentially valid substitute for in-clinic audiometric testing, especially when in-person assessment is not feasible.
  • While Mimi offers comparable accuracy to traditional methods, its user experience requires enhancement.
  • uHear, despite lower accuracy, may offer a more satisfactory user experience, warranting further investigation into its clinical utility.
