Despite the growing demand for online educational resources, there is a notable scarcity of educational materials available in the Korean language. To meet this need, this research developed and evaluated a set of educational materials, including videos and web blogs, focused on fundamental audiology concepts. Evaluation of the material involved a pre-intervention and post-intervention survey with 30 Korean-speaking participants without prior audiology knowledge to measure changes in familiarity, understanding, and self-efficacy. The results showed a significant improvement in all three measured categories indicating the effectiveness of the materials. The greatest improvement was observed in the understanding of audiology concepts. The reach of these materials has been limited, suggesting the need for strategies to enhance their visibility and accessibility. The study concludes that there is a need for further development of audiology education materials in Korean language which may significantly impact knowledge and self-efficacy in managing hearing health.
