Why is air better than bone in tuning fork test?

In the tuning fork test, air conduction is typically better than bone conduction because sound waves travel more efficiently through air than through solid mediums like bone. This is due to the mechanics of sound transmission; air allows for the vibration of air molecules, which can carry sound waves effectively to the ear. Conversely, bone conduction bypasses the outer and middle ear, relying on direct vibration to the inner ear, which may not capture all frequencies as well as air conduction. Thus, a healthy ear usually demonstrates better air conduction, indicating normal auditory function.
