Hearing loss refers to a partial or total inability to hear sounds. It can occur in one or both ears and may result from various factors, including age, noise exposure, infections, or genetic conditions. People with hearing loss may struggle to understand conversations, especially in noisy environments, and may require assistance or devices like hearing aids. There are different types of hearing loss, such as conductive hearing loss, which involves problems in the outer or middle ear, and sensorineural hearing loss, which affects the inner ear or auditory nerve. Early detection and intervention are crucial for managing hearing loss effectively.
