Q
Why do we have different senses of hearing?
A
Expert Answer
Hearing sensitivity varies due to: genetics (congenital hearing differences), age (presbycusis—high-frequency loss with age), noise exposure, ear infections, ototoxic medications, and attention. Some hear frequencies others can't; some have perfect pitch; others are tone-deaf.
