Question

1. why would a person with conductive hearing loss hear the tuning fork through bone conduction longer than or equally as long as through air conduction?

Explanation:

In conductive hearing loss, the problem lies in the outer or middle - ear, which affects air - conduction. Bone - conduction bypasses the outer and middle - ear. Since the problem is in the air - conduction pathway and bone - conduction is not affected by outer/middle - ear issues, a person with conductive hearing loss may hear the tuning fork through bone conduction longer or equally as long as through air conduction.

Answer:

Because in conductive hearing loss, the issue is in the air - conduction pathway (outer/middle - ear) and bone - conduction bypasses this affected area.
