![]() This test helps us determine whether the hearing loss is conductive (caused by problems in the outer or middle ear) or sensorineural (caused by problems in the cochlea, the sensory organ of hearing) or neural – caused by a problem in the auditory nerve or auditory pathways/cortex of the brain. If there is a conductive (middle ear) hearing loss, it is likely to be louder in the affected ear if there is a sensorineural hearing loss (inner ear) it will be quieter in the affected ear. The client is then asked if the sound is localised in the centre of the head or whether it is louder in either ear. The tuning fork is then placed on the forehead. If they can’t there is conductive hearing loss in that ear. When the patient can no longer feel/hear the vibration, the tuning fork is held in front of the ear the patient should once more be able to hear a ringing sound. These tests provide a quick easy method of determining whether a hearing loss is situated in the middle ear or inner ear.Ī vibrating tuning fork is placed behind the ear, on the mastoid process. Tuning forks (this is mine which I’ve owned for 35 years) are used to carry Rinne and Weber tests. 5) Tuning fork tests used alone in evaluation of hearing loss are unreliable and without other diagnostic modalities should not be used.Does the humble tuning fork still have a place in a modern audiology centre? But the reliability obtained with the Bing test at all test frequencies was no clinical value because there are two many false negative response. ![]() 4) Generally the finding of these tuning fork tests compare with pure tone audiogram was identified. 3) The relation of the degree of the hearing loss and tuning fork test, when the air-bone gap was at least 20dB or more, the Bing and the Rinne test was valid and reliable but the Weber test was reliable when the different degree of the hearing loss of the both ear was at lest 10dB or more. ![]() ![]() 2) The most reliable frequency of the tuning fork test, the Bing test was 256 Hz, 512 Hz and 1,024Hz, the Weber test was 512Hz and 1,024 Hz and the Rinne test was 256Hz tuning fork. The conclusions drawn from this study are : 1) The differential diagnosis of conductive hearing loss and sensorineural hearing loss, the more reliable tuning fork test was in order of the Rinne, the Weber and the Bing test. So we evaluate the results of three standard tuning fork tests - the Rinne, the Weber and the Bing - at frequencies of 256, 512 and 1,024Hz as a double blind prospective study of 106 normal persons, 79 patients with air-bone gap and 59 sensorineural hearing loss patients. But there are surprisingly few reports about tuning fork tests as an adjunctive measure in the diagnosis of the hearing loss. The Rinne, the Weber and the Bing test are most widely used for the clinical purpose. Among them tuning fork tests are the most basic and clinically useful. We can have knowledges about degree of hearing impairment and type of hearing impairment through various audiologic tests.
