A key difference between diagnostic and screening procedures is that the diagnostic test is typically accomplished using a pass/fail paradigm.

True

False

false

Air conduction audiometry provides information regarding the degree of hearing loss whereas bone conduction audiometry provides information pertaining to the type of hearing loss.

True

False
