Webtuning fork, narrow, two-pronged steel bar that when tuned to a specific musical pitch retains its tuning almost indefinitely. It was apparently invented by George Frideric Handel’s trumpeter John Shore shortly before Shore’s death in 1752. Because it produces a nearly pure tone (without overtones), it is useful in experimental study of the physics of sound. … WebBone conduction using a tuning fork is specifically used in the Weber and Rinne tests for hearing in order to bypass the middle ear. If just held in open air, the sound of a tuning fork is very faint due to the acoustic … WebOn the sound field radiated by a tuning fork. Daniel A.
