As soon as the fork starts to vibrate it is placed at the mastoid process of the patient.
It should not be struck against metallic object because it can cause overtones. This is the maximum vibratory area of the tuning fork. While striking care must be taken that the strike is made at the junction of the upper 1/3 and lower 2/3 of the fork. It should be struck against the elbow or knee of the patient to vibrate. Under normal circumstances, air conduction is better than bone conduction. It is designed to compare air conduction with bone conduction thresholds. Rinne's test: is a tuning fork test used to clinically test hearing deficiencies in patients. The following tests can be performed using a tuning fork: Will give a rough estimate of the patient’s hearing acuity The vibrating fork should be held parallel to the acoustic axis of the ear being tested.ģ. It is this area of the fork which is capable of maximum vibration. The fork should be struck at the junction of upper 1/3 and lower 2/3 of the fork. The tuning fork must be struck against a firm surface (rubber pad / elbow of the examiner).
#WEBER TUNING FORK USED FOR FULL#
It should be capable of maintaining the vibration for one full minute It should vibrate at the specified frequencyģ. Sensitivity for frequencies above 1024 Hz is rather poor and hence is not used.Ģ. Frequencies below 254 Hz are better felt than heard and hence are not used. This test can in fact be performed by using tuning forks of the following frequencies (254 Hz, 512 Hz, and 1024 Hz). These tests are performed in order to subjectively assess a person’s hearing acuity.
