Virtual audiometric testing using smartphone mobile applications to detect hearing loss

Abstract

Objective: The COVID-19 pandemic drove the need for remote audiometric testing in the form of mobile applications for hearing assessment. This study sought to determine the accuracy of two smartphone-based hearing assessment applications, Mimi and uHear, against the gold standard of in-clinic audiometric testing. Methods: One hundred patients that presented to clinic for hearing assessment were randomly assigned to take either the Mimi or uHear hearing test alongside standard audiometric testing. Hearing thresholds measured using mobile applications were compared to those from audiometric testing to assess validity. Patient satisfaction was measured using a questionnaire that queried if the app met the user's need, if they would recommend the app to others, and how likely they were to use the app again. Results: Using Mimi, there were no differences in average hearing levels measured at any frequency when compared to standard audiometric testing. uHear overestimated hearing loss at 500 and 1000 Hz (p
