Tablet audiometry: Comparison of automated game-based and tester-assisted procedures in children

Access to hearing health care in developing countries and for individuals living in rural areas is a challenge. This has prompted the development of portable audiometry using automated game-based procedures via smartphones and tablets. Objectives: The purpose of this study was to compare the automated game-based and tester-assisted (conventional procedure administered via a tablet) options available on a tablet audiometer with children outside a clinical environment. Methods: 58 children ages 5-12 years were tested using a tablet audiometer at four different after-school facilities, with half the children completing the automated game-based procedure and half completing the conventional (tester-assisted) procedure administered via the tablet. Seven of the children completed both procedures. Results: The tester-assisted procedure was found to be significantly more efficient than the automated game-based procedure, both in terms of time taken to provide test instructions, and for the duration of the testing. Conclusion: Although tablet audiometry has been found to be accurate and reliable, the currently available automated game-based procedure takes longer than the tester-assisted mode. The game-based procedure could be improved by adding automated reinforcement to make it more engaging for children ages 5-12 years.
