← Human Body & HealthAs sound exposure accumulates during a person's life, what causes high-frequency hearing loss typically appearing before low-frequency loss?
A)Ossicle chain stiffening with age
B)Basal hair cell cumulative damage✓
C)Endolymphatic hydrops accumulating damage
D)Tectorial membrane increased mass
💡 Explanation
High-frequency sounds stimulate the basal end of the cochlea; therefore, the basal hair cells experience more cumulative noise exposure and are more susceptible to damage, leading to hearing loss. This is basal hair cell cumulative damage, rather than other cochlear structures being directly affected.
