According to a recent study published by hear it.org, as many as 35 percent of school-children in Argentina suffer from hearing damage.
Tests conducted among 450 pupils ages 6 through 13 years in Argentina found that more than one third of them suffered from some degree of hearing loss. This prevalence is much higher than previously believed. In general, data from earlier similar studies indicated a prevalence of 10 to 14 percent of school aged children with hearing difficulties.
Researchers asked the children to listen and repeat sentences while the environmental noise was being gradually increased.
