The main objectives are:\n\n* To evaluate the HoorToren's effects on promoting the child's safe listening behavior when using headphones or earbuds. Both safe listening and its psychological determinants will be measured.\n* To evaluate the HoorToren's effects on parents' perception of their child's safe listening behaviors. The effects on parental behavior promoting or facilitating their child's safe listening behavior, including its psychological determinants, will also be evaluated.\n\nResearchers will compare children who receive lessons from the HoorToren educational program, and their parents (intervention group) with children and their parents who do not receive the lessons (control group) to evaluate the effectiveness of the HoorToren. Outcomes will be assessed using newly developed and validated self-report questionnaires for both children and their parents. Additionally, the child's listening behavior will be measured via a smartphone application installed on the child's phone. Measurements will take place at four time points during the school year.",[69,70,71,72],"Effectiveness of Application Education Intervention","Noise Induced Hearing Loss","Behavior Change Interventions","Primary School Children",[74,75,76,77,78],"Noise-induced hearing loss","Prevention","Primary school","Randomized controlled trial","Effectiveness","2026-03-30",{"date":81,"type":82},"2026-04-06","ACTUAL",{"date":79,"type":82},{"date":85,"type":63},"2027-08",{"name":5,"class":6},1]
