What is Rinne and Weber test?
Rinne and Weber tests are exams that test for hearing loss. They help determine whether you may have conductive or sensorineural hearing loss. This determination allows a doctor to come up with a treatment plan for your hearing changes. A Rinne test evaluates hearing loss by comparing air conduction to bone conduction.
What does lateralization in Weber test mean?
In a patient with hearing loss, the Weber tuning fork sound is heard louder in one ear (lateralization) than the other. This clinical finding should be confirmed by repeating the procedure and having the patient occlude one ear with a finger; the sound should be heard best in the occluded ear.
What is the Rinne’s test and what does it test for?
The Rinne test differentiates sound transmission via air conduction from sound transmission via bone conduction. It can serve as a quick screen for conductive hearing loss. A Rinne test should be done in conjunction with a Weber test to detect sensorineural hearing loss.
What does a positive Weber test indicate?
The test can detect unilateral conductive and sensorineural hearing loss. The outer and middle ear mediate conductive hearing. The inner ear mediates sensorineural hearing. The Weber test is often combined with the Rinne test to detect the location and nature of the hearing loss.
How is Weber test performed?
The Weber test compares hearing in the two ears with each other. A vibrating tuning fork is held midline against the patient’s forehead (A). The patient is asked whether one ear hears the fork more loudly. Unequal perception of sound indicates a conductive deficit in the loud ear or a neural deficit in the quiet ear.
Why is Rinne positive in SNHL?
A positive Rinne occurs when air conduction is perceived louder than bone conduction. This is seen in normal listeners or patients with sensorineural hearing loss (SNHL). Conversely, when a sound is heard louder from the mastoid, this is a negative Rinne test and is indicative of a conductive hearing loss (CHL).
How do I read my Weber test results?
How do I interpret Weber’s? If a patient has a unilateral sensorineural hearing loss, the sound will lateralise – move to the good ear. If a patient has unilateral conductive hearing loss, the tuning fork sound would be heard loudest in the affected ear.
Why do we use 512 Hz tuning fork?
Results: Results showed the 512-Hz Rinne tuning fork test could be very effective at detecting conductive hearing losses when performed by an experienced tester and when masking was used. Sensitivity was lower when masking was not used and lowest when the Rinne was performed by a less-experienced tester.
How do you do Rinne’s test?
Rinne test: Place the base of a struck tuning fork on the mastoid bone behind the ear. Have the patient indicate when sound is no longer heard. Move fork (held at base) beside ear and ask if now audible. In a normal test, AC > BC; patient can hear fork at ear.
What is a normal Weber test result?
Weber test: Place the base of a struck tuning fork on the bridge of the forehead, nose, or teeth. In a normal test, there is no lateralization of sound. With unilateral conductive loss, sound lateralizes toward affected ear. With unilateral sensorineural loss, sound lateralizes to the normal or better-hearing side.
How do you read Rinne and Weber test?
AC > BC: Air conduction better than bone conduction (normal Rinne). BC > AC: Bone conduction better than air conduction (abnormal Rinne)….
| Weber lateralizes | Rinne test | |
|---|---|---|
| Good ear | AC > BC | |
| Bad ear | To bad ear | BC > AC |
| Sensorineural loss | ||
| Good ear | To good ear | AC > BC |
How do you use a Weber?
How to do Weber’s Test
- To perform Weber’s test strike the fork against your knee or elbow, then place the base of the fork in the midline, high on the patient’s forehead.
- Then ask the patient: “Do you hear the sound louder in one ear than the other?”
