Suppose that you are sitting in a living room and your head is a
stereo audio system with the fork being the pick up transducer. Your
eardrums will be the membranes of the loudspeakers which transmit energy
in the form of mechanical waves. More of this energy will be dissipated if
the the windows (ie. the outer ear) are open. Conversely, the desired
loudness will be achieved on a lower output setting when the windows are
closed.
Therefore, the difference in hearing sensation between the two ears during
a Weber's test is caused by the reduced energy dissipation on the ill
side.
