Hearing Impairment

Hearing Impairment

Summary

Approximately 466 million or 5 percent of people worldwide have a disabling hearing impairment, 34 million of which are children. A disabling loss of hearing is classified as any loss greater than 40 dB from the standard level of hearing in a healthy adult ear. For children, it is classified as any loss greater than 30 dB from the level of hearing in a healthy child’s ear.1 In developing nations, children and adults with hearing loss face barriers in accessing education or becoming part of the workforce.2 Hearing loss can be genetically acquired or be caused by complications during birth, disease, chronic ear infections, certain medications, overexposure to loud noise or aging. 3 Diseases that can cause hearing loss include meningitis, measles, mumps, rubella and syphilis.4 Certain drugs used to treat malaria, and medications used to prevent neonatal infections, can also cause hearing impairments.5 Show References
