About the study

A total of 79,340 children from grades 1 through 10 from 509 government schools in Nepal were included in the study. The children were screened for ear diseases in their respective classrooms by otoscope. Hearing evaluations were carried out with a pure tone audiometer and hearing threshold was obtained at 0.5 – 4 kHz.

The study was conducted from January 2015 through December 2019 by a team of Ear, Nose and Throat surgeons and audio technicians.

The study, "Prevalence of hearing loss in school aged Nepalese children", was published in the International Journal of Pediatric Otorhinolaryngology
