A test to see if both ears hear correctly, where a tuning fork is struck and the end placed on the head [After Friedrich Eugen Weber-Liel (1832-91), German otologist].
A hearing test in which a vibrating tuning fork is placed at the midpoint of the forehead. A normal individual hears it equally in both ears, but if one ear is affected by conductive deafness the sound appears louder in the affected ear.
