School hearing tests do not detect noise exposure hearing loss

School hearing tests cannot effectively detect adolescent high-frequency hearing loss, which is typically caused by loud noise exposure, according to researchers. School screenings primarily focus on low-frequency hearing loss. This is logical for young children, who are more likely to develop low-frequency hearing loss due to fluid in the ear after a bad cold or an ear infection. Adolescents, however, are more susceptible to high-frequency hearing loss, usually brought on by exposure to loud noises, but the same tests are used on adolescents and young children.
