Hearing impairments refer to a range of conditions that affect a person's ability to hear sounds. These can vary from mild difficulties in hearing certain frequencies to complete deafness. Causes may include genetic factors, exposure to loud noises, infections, or age-related changes. People with hearing impairments often use tools like hearing aids or cochlear implants to assist with their hearing. Communication methods may also include sign language or lip-reading. Early detection and intervention are important for improving outcomes and enhancing the quality of life for those affected.
