Impact of Language Barriers and Age on English Hearing Test App Accuracy for Polish Users.

Objective: The development of health applications (apps) includes those for testing hearing, although most of them are available only in English. This study investigates whether poor English language proficiency creates a barrier for Polish users in the accuracy of such an app in measuring self-determined hearing thresholds.

Study Design: The study compared hearing thresholds measured by an English-language app and a professionally conducted reference test, with attention to participants' English proficiency and age.
