Common Hearing Loss Presbycusis (Age-Related Hearing Loss)
Presbycusis is the gradual loss of hearing that occurs as people age. It is one of the most common sensory impairments in older adults, typically starting after the age of 50 and progressing over time. Causes
Degeneration of Inner Ear Structures:
Damage to hair cells in the cochlea, which play a key role in converting sound waves into electrical signals for the brain.
Changes in the Auditory Nerve:
Reduced ability of the auditory nerve to transmit signals effectively.
Circulatory System Changes:
Reduced blood flow to the inner ear, affecting its function.
Environmental Factors:
Long-term exposure to loud noises can accelerate hearing loss.
Genetic Predisposition:
Family history of hearing loss may increase risk.
Symptoms
Difficulty hearing high-pitched sounds (e.g., birdsong or women's voices).
Trouble understanding speech, especially in noisy environments.
Perception that others are mumbling or speaking unclearly.
Needing to increase the volume on televisions or radios.
Ringing in the ears (tinnitus) may also accompany presbycusis.
Diagnosis Presbycusis is typically diagnosed through:
Hearing Tests: Audiometry to assess the range and degree of hearing loss.
Medical History and Examination: Identifying contributing factors like noise exposure or family history.
Hearing aids are proven to be the most effect tool in slowing the progression of a hearing loss!
