A 24-year-old female asked:
with weber's hearing test, y is conduction through air twice faster than through bone, even though sound travels faster in denser medium?

Whoa: There is no such thing as a perfect medical school instructor. The weber has nothing to do with the speed at which sound is conducted. It takes advantage of the fact that sound conducted through bone will be perceived more readily in an ear that has conductive hearing loss -- it's not the speed at which the sound arrives, but the intensity at which it is delivered.

Weber test : You're right, sound is faster in bone than air, but the weber test is not measuring the speed of sound but rather its intensity ( perceived loudness). With normal hearing air conduction should be louder than bone conduction...Not faster. With an appreciable conductive loss bone conduction is louder than air conduction. Good luck in school.
