목적: 1) observe hearing and listening behavior in the students, 2) design the Safe- Listening intervention, and 3) assess the effectiveness of the Safe-Listening intervention 방법:This project composed of prospective one-group pretest-posttest design study was conducted in Chiangmai Rajabhat University Demonstration School during the first semester of the year 2023. This project had 2 main activities: promotional activities and an educational program. The education covered 3 main topics: i) basic anatomy of ears, ii) common environmental noise level and noise- induced hearing loss, and iii) hearing protection. The effectiveness of the intervention was assessed by before and after self-reported questionnaires. Hearing behaviors were evaluated by self-reported and proxy-reported questionnaires. 결과:There were 228 parents and 200 students who completed the questionnaire. Of parents, 28.64% reported a high degree of worrying about their childrens hearing loss, 63% reported never leaving their children exposed to loud noise, and 59.65% reported never informing their children to use hearing protective devices. Of the students, 19.5% feel having difficulty hearing, 50% did not know their hearing status, 30% did not want to use hearing protection devices, and 30% thought that it is impossible to be deaf from loud noise exposure. The mean score of students knowledge about hearing after the program was higher, but it was not statistically different. 결론:Hearing health promotion and safe listening behavior project should raise awareness of hearing loss prevention, change hearing behavior affecting hearing, and decrease the prevalence of noise-induced hearing loss. Further studies in a larger population regarding cost-effectiveness and cost- benefit analysis of the intervention were suggested.
