Humans typically hear sounds between 20 and 20,000 Hertz (Hz) . This range naturally declines with age, particularly for higher frequencies.
Home to the cochlea , a snail-shaped, fluid-filled organ. Inside the cochlea, thousands of microscopic "hair cells" convert mechanical vibrations into electrical signals. 2. Sensitivity and Selectivity
The human ear is divided into three primary sections, each functioning as a critical link in the auditory chain:
Issues in the outer or middle ear (e.g., earwax buildup or fluid).
The human ear's sensitivity is staggering; it can detect sound-wave-induced vibrations of the eardrum that move by less than the .
