Hearing loss was often mild and moderate, and audiogram configuration was primarily high tone loss (HTL). On the whole, 8.13% of students needed medical treatment, 15.13% needed audiological rehabilitation and 3.44% of them were in need of both medical and rehabilitation Intervention. General information about hearing problem was very low among students, their parents and teachers, which was 26.87%, 20.9% and 22.39%, respectively. There is significant relation between SNHL and parents&apos relationship.
Conclusion: The prevalence of hearing loss in blinds is higher than in normal-visions. It is often sensorineural. So, it is important to identify these children through hearing screening (Using more high frequencies) and to conduct medical as well as rehabilitative intervention.
