How To Perform A Tuning Fork Hearing Test
A tuning fork hearing test is a bone conduction hearing test doled out to ascertain the hearing acuity in a patient.The clinical tuning fork tests include both the Weber test and Rinne test. Broadly the tuning fork hearing test determines if the hearing loss is sensorineural or conductive hearing loss.If the loss is severe then the doctor might refer for hearing aids. Hearing devices must be bought with reference to the audiological report and under professional supervision.
* In doing the weber test a vibrating tuning fork is placed vertically on the middle of the forehead.
* The process is simple and painless. In weber test the sound is directly transmitted to the cochlea of the ear.
* The process yields results…… if the patient hears the sound in both the ears then the hearing is normal and there can be a hearing loss if the patient hears the sound more in one ear than the other.there is a conductive loss in the ear which hears better or that there is a sensorineural loss in the ear which does not hear as well.
* In doing the Rinne’s test again a vibrating tuning fork is placed on the mastoid bone behind each ear of the patient and then placed just outside the ear.
* If the result is normal and its positive Rinne then the patient would hear the sound louder when the tuning fork is held right outside the ear compared to the sound when the tuning fork is held on the mastoid.
* If the outcome is not normal or negative Rinne then its a bone conduction hearing loss rather than air conduction hearing loss.
* Both the Weber and Rinne tests are basic hearing screening tests. They cannot be substituted with other audiometry hearing test.
