Which condition describes hearing loss associated with aging?

• A. Pulmonary
• B. Presbycusis
• C. Radius
• D. Pronation

Answer: (B)

Age-related hearing loss is called presbycusis. It reflects gradual, sensorineural decline of the auditory system as we age, typically affecting both ears and starting with higher frequencies, which makes it harder to understand speech in noisy environments. This degeneration involves hair cells in the cochlea and changes in neural pathways, often amplified by lifelong noise exposure or genetics. The other terms don’t fit because they refer to unrelated body systems or movements: pulmonary relates to the lungs, radius is a bone in the forearm, and pronation is a rotational forearm movement.
