Mürakahjustus

Mürakahjustus refers to hearing loss caused by exposure to loud noise. This can occur from a single, extremely loud event, such as an explosion or gunshot, or from prolonged exposure to moderately loud noise over time, like working in a factory or attending concerts regularly. The damage typically affects the sensitive hair cells within the inner ear, which are responsible for converting sound vibrations into electrical signals that the brain interprets as sound. Once these hair cells are damaged or destroyed, they cannot regenerate, leading to permanent hearing loss.

The symptoms of mürakahjustus can vary. In cases of acute exposure, individuals might experience temporary hearing loss, ringing in the ears (tinnitus), or a feeling of fullness in the ear. Chronic exposure can lead to a gradual decline in hearing, often affecting the ability to hear higher frequencies first. This can make it difficult to understand speech, especially in noisy environments. Tinnitus is also a common and persistent symptom for many who have experienced noise-induced hearing loss.

Preventing mürakahjustus involves minimizing exposure to loud noises. This can include using hearing protection, such as earplugs or earmuffs, in noisy environments. It also involves being mindful of noise levels in daily life, such as turning down the volume on personal listening devices and avoiding prolonged exposure to sounds above 85 decibels. Early detection through regular hearing tests can help identify damage before it becomes severe.
