and, sadly, that school checkups failed to identify adolescents with hearing loss. Korea Biomedical Review reports that “[i]nadequate hearing tests done by schools have been unable to find many teens with hearing problems resulting from the portable audio system and frequent visits to Internet cafes.” The results call into question “statistics at Korea’s Center for Disease Control and Prevention (KCDC) and school tests conducted in 2010.”
The implications are significant:
The [study] found that 12.7 percent of seventh-grade students and 10.4 percent of 10th-grade students fell into the World Health Organization’s category of hearing loss (cannot hear at 15 decibels). When the high frequency is included, 17.9 percent of the 7th graders and 16.5 percent of 10th graders belong to the category of possible noise-induced hearing loss.
By contrast, school tests conducted in 2010 only found 5.4% of students with hearing loss.
The researchers cautioned that “[h]earing impairment can affect a student’s academic performance and can continue to create barriers to communication in social life and the workplace,” adding that “[t]he social cost of neglecting this problem can reach up to 72.6 billion won ($63.6 million).”
Meanwhile, in the U.S., are hearing exams required in primary schools? They should be, because regular hearing exams would identify children at risk of hearing loss and would make children aware of the importance of protecting their hearing.
