Abstract

Introduction: The global prevalence of hearing loss is around 5 percent in low to middle-income countries. The main purpose of this study is validating a mobile-based Pure Tone Audiometry (PTA), Dichotic Digit Test (DDT) and Speech in Noise (SIN) hearing tests for hearing loss screening purposes in Persian people comparing with routine audiometry exam results.

Material and Methods: This is a single blind randomized controlled trial for comparing a mobile application for hearing screening exams. We designed and standardized PTA, DDT and SIN tests for Persian people and settled them into a specific developed mobile application called “Shenava®”. In the audiology clinic, we will recruit at least 100 healthy adult participants, 50 for the case and 50 for the control group. The first group will pass “Shenava®” and standard test respectively and the other group will pass the tests vice versa to prevent order bias.

Results: The results of the tests performed by “Shenava®” and audiometry exam will be analyzed to ensure the accuracy and validity of the” Shenava®” in comparison with standard audiometric exam results.

Conclution: Hearing tests are costly even for time and money and need a lot of efforts for audiologists and the patients. By designing a mobile app for hearing tests, we hope to be able to make diagnostic screening easier for hearing loss, and relying on the diagnostic value of this tool, it may encourage the patients to have a better follow up and effective treatment plan.
