Therefore, combining the result of each other test together helps in finding out the nature and location of certain hearing impairment.Ī Sensorineural hearing loss occurs from the gradual damage to the hair cells in the cochlea. The Rinne and Weber tests are usually performed together.

These tests require a full examination of the cranial nerves or the ear. By determining the type of hearing loss, it helps the doctor to start a treatment plan related to the hearing impairment. They help in determining the type of unilateral hearing loss such as sensorineural or conductive hearing loss. Interpretation of Rinne and Weber test is the hearing disability of a person. And the person is then asked regarding sound that is heard more at the place where it is produced which is the middle of the skull or only in one specific ear.Ī good examiner always tries to hold the vibrating fork parallel to the acoustic axis of the ear of the patient.
Early evaluation allows you to get early treatment which can prevent total hearing loss.īefore discussing the Rinne and Weber test, first, we will discuss some points about Tuning Fork Test as it has a huge contribution in both of these tests.Ī vibrating fork of 512 Hz frequency is set in the center of the skull. It evaluates the level of hearing loss by comparing air conduction to bone conduction. You can purchase the latest hearing aids at a fair price through HearingSol, If you need any assistance or you have a query regarding Rinne and Weber Tests, Tuning Fork Test and Hearing Loss, feel free to call us at +91-9899437202. With the help of Rinne and Weber test, a doctor determines hearing loss and comes up with a treatment plan for your hearing changes. Today our topic is going to deal with Rinne and Weber Test, a type of tuning fork test. Get Overview of Tuning Fork Test.Īs your overall treatment depends on your particular hearing problems. Audiologist performs these tests to satisfy the conditions of hearing loss. As the rocket passes the students, they hear a noticeable shift in frequency.The hearing test is very important in order to identify the relying cause behind your hearing problems. The Doppler Rocket emits a sinusoidal sound waveform at a constant frequency of approximately 620 Hz. As the whistle rotates in a circle, the listener will hear a different pitch depending on the direction of its motion relative to the listener. One can also choose between blowing steadily into the rubber tubing and mouthpiece, or attach the rubber hose to the air supply faucet.

The apparatus can be set on a manual rotator or on a motor-driven rotator, at a moderate speed. This apparatus is designed to show that the pitch of a sound changes depending on whether the source is moving towards or away from the listener. The class should be able to hear the changes in pitch. Hit it with the provided rubber hammer and rotate it on an horizontal plane above your head. The tuning fork has a string attached to its stem.
In this demo Doppler effect is demonstrated by swinging a vibrating tuning fork as shown below. The waves preceding the source are compressed, those following it are spread out.

With the wave generator's frequency adjusted to about 10 Hz, move the stand that holds the wave generator from left to right and back. Doppler effect is easily and effectively demonstrated using a point source producing circular waves with their origin near the center of the tank.
