Health care professionals use an air conduction test to determine how your ears respond to sound in the air around the ear. This simple and painless procedure is also known as the Weber test. It involves striking a tuning fork and hold it close to your head. The amount of time you can hear the sound is recorded and compared to the results of your bone conduction test. The specialist may also hold the tuning fork in the middle of your head and then ask if you hear from one side or the other once the fork is struck.
