What distinguishes presbycusis-related hearing loss from noise-induced hearing loss in a sound engineer who regularly monitors high-decibel audio?

💡 Explanation

Presbycusis selectively damages hair cells responding to high frequencies due to cumulative oxidative stress and genetic predisposition, therefore high-frequency hearing is lost first, rather than an equal distribution of damage seen in early noise-induced trauma, because the cochlear base is more vulnerable.
