Hearing impairment refers to a partial or total inability to hear sounds. It can occur in one or both ears and may affect people of all ages. Causes of hearing impairment include genetic factors, exposure to loud noises, infections, and aging. The severity can range from mild difficulty in hearing certain sounds to profound deafness, where no sound is heard at all. Individuals with hearing impairment may use various tools to assist with communication, such as hearing aids or cochlear implants. Additionally, sign language is often used as an effective means of communication. Early diagnosis and intervention can significantly improve the quality of life for those affected.
