Screening for hearing loss among school going children

Abstract

Hearing loss results from a deviation in the perception of sounds in one's environment. A child may have hearing loss at a hearing threshold of ≥16 dB. Hearing loss is among the frequent disorders and affects lots of people globally. Hearing loss negatively affects many areas needed for classroom learning, language development, academic performance, and social development. These consequences can be reduced by early detection with appropriate audiological and speech therapy interventions. In developing countries like Ghana, there is no such laid down formal hearing screening programs for early detection of any signs of impairments. The present study was aimed at identifying the prevalence and causes of hearing loss among basic school children aged between 5 and 17 years at Freetown Basic School, Ho. The study sought to determine the causes and prevalence of hearing loss. Out of the 210 participants, 44 (21%) failed the audiometric screening test. Out of the 44 students who failed the audiometric screening test, 25 (11.9%) had hearing loss across all the test frequencies. Prevalence of hearing loss among basic school children was found to be 11.9%. This shows that hearing loss is not uncommon among school going children in the Ho Municipality. It was determined from the study that the prevailing causes of the hearing impairments may be attributable to abused use of ototoxic drugs and ear-aches and infections with majority of participants recording mild hearing loss. It can be concluded that hearing loss among school going children is preventable if appropriate measures are put in place.
