Presbycusis and Hearing
Captions available
The idea
Presbycusis, age-related hearing decline, begins with high-pitched tones; lifelong noise exposure is a major predictor, and men lose more hearing than women.
In practice
A grandfather who hears his son's voice but misses his granddaughter's higher one.
Where people slip
The misconception is that presbycusis means everything sounds quieter; high pitches go first, and damage accumulates from youth.
