Student A:Context: The Weber and the Rinne test (/ rn / RIN-) are typically performed together with the results of each combined to determine the location and nature of any hearing losses detected. In the Weber test a vibrating tuning fork (Typically 256 Hz or 512 Hz used for Weber vibration test; 512 Hz used for Rinne hearing test) is placed in the middle of the forehead, above the upper lip under the nose over the teeth, or on top of the head equi-distant from the patient's ears on top of thin skin in contact with the bone. The patient is asked to report in which ear the sound is heard louder. A normal weber test has a patient reporting the sound heard equally in both sides. In an affected patient, if the defective ear hears the Weber tuning fork louder, the finding indicates a conductive hearing loss in the defective ear. In an affected patient, if the normal ear hears the tuning fork sound better, there is sensorineural hearing loss on the other (defective) ear. However, the aforegoing presumes one knows in advance which ear is defective and which is normal (such as the patient telling the clinician that they can not hear as well in one ear versus the other) and the testing is being done to characterize the type, conductive or sensorineural, of hearing loss that is occurring. In the case where the patient is unaware or has acclimated to their hearing loss, the clinician has to use the Rinne test in conjunction with the Weber to characterize and localize any deficits. That is, an abnormal Weber test is only able to tell the clinician that there is a conductive loss in the ear which hears better or that there is a sensorineural loss in the ear which does not hear as well.

Question: where is the tuning fork placed when the weber test is performed?
