Rinne and Weber tests both use 512-Hz The hertz (symbol Hz) is the unit of frequency in the International System of Units (SI) and is defined as one cycle per second. It is named for Heinrich Rudolf Hertz, the first person to provide conclusive proof of the existence of electromagnetic waves.Hertz
What is the difference between Rinne's test and Weber’s test?
In healthy individuals, Rinne’s test is positive (indicating air conduction is better than bone conduction) and Weber’s is heard in the midline. In patients with conductive hearing loss, Rinne’s test is negative (indicating bone conduction is better than air conduction) on the affected ear and Weber’s test localises to the affected ear.
What tuning forks are used in the Weber and Rinne tests?
Rinne and Weber tests both use 512-Hz tuning forks to test how you respond to sounds and vibrations near your ears.
What are the results of the Weber test?
Weber Test results 1 Normal hearing will produce equal sound in both ears. 2 Conductive loss will cause the sound to be heard best in the abnormal ear. 3 Sensorineural loss will cause the sound to be heard best in the normal ear. More ...
Why is Rinne’s test so difficult to interpret?
The difficulty in interpreting Rinne’s test is in total unilateral sensorineural hearing loss (i.e. a ‘dead’ ear) For example, imagine the right ear is ‘dead’.
How do you read Rinne test results?
Rinne Positive: The patient is positive on that side (the ossicular chain is doing what it should be doing, acting as an amplifier). If the bone conduction through the mastoid process is heard louder than through the air, the patient is Rinne negative. This is always abnormal.
What is the normal findings of the Weber test?
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.
What does a positive Weber test indicate?
Weber test performance 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.
How do you remember Rinne and Weber?
Back to basics ^ → Rinne's : tuning fork on mastoid bone. Heard side is sick side if it's a perception deafness. Weber's : tuning fork on forehead. Heard side is sick side if it's a conductive deafness.
How do you know if hearing loss is sensorineural or conductive?
If the hearing loss is conductive, the sound will be heard best in the affected ear. If the loss is sensorineural, the sound will be heard best in the normal ear. The sound remains midline in patients with normal hearing. The Rinne test compares air conduction with bone conduction.
What does Rinne test measure?
The Rinne test looks for differences in how your ears hear sound transmitted through the air versus sound transmitted through your bone. While further testing is needed to diagnose the degree of hearing loss, this test is a way to quickly test for conductive hearing loss.
What does it mean if air conduction is greater than bone conduction?
If the bone conduction is the same or greater than the air conduction, there is a conductive hearing impairment on that side. If there is a sensorineural hearing loss, then the vibration is heard substantially longer than usual in the air.
How do you say Rinne test?

And say yes when you can hear them and now when they stop again. Okay.
Which results are to be expected from the Rinne and Weber tests in a patient with conductive hearing loss in the right ear?
Weber Test results Normal hearing will produce equal sound in both ears. Conductive loss will cause the sound to be heard best in the abnormal ear. Sensorineural loss will cause the sound to be heard best in the normal ear.
What does it mean if air conduction is greater than bone conduction?
If the bone conduction is the same or greater than the air conduction, there is a conductive hearing impairment on that side. If there is a sensorineural hearing loss, then the vibration is heard substantially longer than usual in the air.
When is Rinne test positive?
The Rinne test is not reliable in distinguishing sensorineural and conductive loss cases of severe unilateral or total sensorineural loss. In such cases, bone conduction to the contralateral normal ear will be better than air conduction, resulting in a false negative.
What does conductive hearing loss mean?
A conductive hearing loss happens when sounds cannot get through the outer and middle ear. It may be hard to hear soft sounds. Louder sounds may be muffled. Medicine or surgery can often fix this type of hearing loss.
What is a 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.
Why do doctors use Rinne and Weber?
Doctors benefit from using Rinne and Weber tests because they are simple, can be done in the office, and are easy to perform. They’re often the first of several tests used to determine the cause of hearing change or loss. The tests can help identify the conditions that cause hearing loss.
What frequency tuning forks do Rinne and Weber use?
Rinne and Weber tests both use 512-Hz tuning forks to test how you respond to sounds and vibrations near your ears.
How does the Rinne test work?
A Rinne test evaluates hearing loss by comparing air conduction to bone conduction. Air conduction hearing occurs through air near the ear, and it involves the ear canal and eardrum. Bone conduction hearing occurs through vibrations picked up by the ear’s specialized nervous system.
Can Rinne and Weber test cause hearing loss?
There are no side effects of Rinne and Weber tests. After you have the tests, you’ll be able to discuss any necessary treatment options with your doctor. Further examinations and tests will help determine the exact location and cause of the type of hearing loss you have.
Is Rinne and Weber a noninvasive test?
Rinne and Weber tests are noninvasive and cause no pain, and there are no risks associated with them. The information they provide determines the type of hearing loss you may have, especially when the results of both tests are used together.
Do you need to go to the doctor for a Rinne test?
The Rinne and Weber tests are easy to perform, and there’s no special preparation required. You will need to go to the doctor’s office, and the doctor will conduct the tests there.
What is a positive and negative Rinne’s Test?
A patient who hears the tuning fork loudest when held 1cm from the external auditory meatus has a positive Rinne’s test
How much hearing loss can Rinne detect?
Rinne’s test can only detect a conductive hearing loss of at least 30dB. Explain the test first: “I’m going to put this vibrating tuning fork in two positions, one touching the bone near you ear, one a short distance from the ear. I want you to tell me which position you hear the tuning fork loudest in”.
What test is used for tuning forks?
Other tuning fork tests include the Schwabach and Bing tests, though these are not used in routine practice
How to use a tuning fork for mastoid?
Begin by striking the tuning fork against your knee or elbow. Hold the tuning fork in one hand and place the base against the patient’s mastoid process ( see video ) Allow it to stay there for 2-3 seconds to allow them to appreciate the intensity of the sound.
How do I do Rinne’s test?
Before you begin the exam, it is important to explain to the child what you are about to do to in way they can understand. Try to put them at ease and make sure they are sitting comfortably, ideally in a silent room. Ask about pain especially over the mastoid.
How do I interpret Rinne’s test?
In a normal ear, air conduction is greater than bone conduction, that is to say sound is more efficiently transmitted to the cochlea via air than via bone. So, a patient who hears the tuning fork loudest when it is placed 1cm from the external auditory meatus has a positive Rinne’s test and a person who hears loudest when placed over the mastoid process has a negative Rinne’s test. The challenge in making these interpretations is in the case of a false positive Rinne’s test where there is unilateral sensorineural hearing loss. This is where Weber’s test is most useful in providing further clues.
What is tuning fork test?
The tuning fork tests. Weber and Rinne tests are reliable and useful tools for assessing hearing loss in older, verbal children. They help distinguish between conductive and sensorineural hearing loss and so are more useful in patients with unilateral hearing difficulty.
How are auditory anomalies picked up?
Auditory anomalies, in newborns, are exclusively picked up via universal screening programmes. In older children, the presentation is usually similar to Sarah’s story. They may have behavioural changes, delayed language skills or listen to the TV at a louder volume than everyone else.
What is Weber and Rinne test?
Weber and Rinne tests are reliable and useful tools for assessing hearing loss in older, verbal children. They help distinguish between conductive and sensorineural hearing loss and so are more useful in patients with unilateral hearing difficulty. Children with mixed, or bilateral hearing loss, should be referred to an ENT specialist for a more formal pure tone audiometry assessment. It doesn’t matter which test you perform first. These tests should, however, be performed with a full cranial nerve and neurological exam.

How to test for conductive hearing loss?
Rinne test basics. The doctor places the base of the struck tuning fork against your mastoid bone behind your ear. They play a sound and ask if you can hear it. Then they move the fork next to your ear and ask again if you can hear the sound. Normally, you can hear with the fork placed beside your ear. If you have conductive hearing loss, you may not hear the sound with the fork at your ear.
Why do doctors use Rinne test?
Medical professionals primarily use the Rinne test when they suspect conductive hearing loss. They also use it for patients who have a condition called otosclerosis, to help determine if they are a candidate for surgery.
Can you hear speech with softer toners?
