ABSTRACT
Obviously, if the fork is heard either in your ear or in the patient's good right ear but not in his left, or bad, ear, he/she probably has some hearing loss in the left one. Then, by striking the tuning fork a little harder each time and listening with your own normal ear before and after you place it to the patient's left ear, you can determine how loud the fork's vibrations must be for the patient to hear them. In this way, a rough idea of the degree of his hearing loss can be gained.
