This hearing loss test, hearing test in adults especially helps in determining the range of pitches that an individual can hear. This pure-tone test for hearing loss picks out the faintest tones an individual can hear at several pitches or frequency. This test is not at all painful and patients need not have to worry.
The individuals have to wear headphones during the pure-tone test. Through the headphones, a sound is to be played; and if the sound is audible to the person then they need to raise a hand or respond by saying ‘yes”. For getting accurate results from the test, each ear will be individually tested.
Another hearing loss test is speech test. During this test, the patient who is to be tested, is asked to listen to conversation in noisy and quiet environment. For determining the person’s speech reception threshold, the doctor or audiologist will be recoding word recognition or the patients’ ability to repeat the words again.
Auditory Brainstem Response:
There is another hearing loss test for adults known as the auditory brainstem response. This test provides an audiologist the information about the inner ear and the pathways of brain which are required for our hearing. Here electrodes are placed on the patient’s head for recording the brain wave activity.
Middle Ear Test:
Middle ear test is also required to test hearing loss in adults. For testing the functioning of your middle ear, the audiologist will have to get the measurements, like tympanometry, static acoustic measures and the acoustic reflex measures.
During this test, the audiologist will push air pressure into the canal and thus cause the eardrum to vibrate back as well as front.
Acoustic reflex measures offer your data regarding the location of any hearing problem. Acoustic reflex is actually the contraction of your middle ear occurring when a loud sound is introduced. Testing for your acoustic measure helps the audiologist to identify the problem in your eardrum and check the opening of the ventilation tubes of the ear.
Otoacoustic emissions are the sounds which are given off by our inner ear when there is a kind of stimulation in the cochlea by sound; are usually measured for narrowing down the types of hearing loss. Such otoacoustic emissions are measured usually by inserting a tiny probe into your ear canal, which is known to measure sounds that is produced by the vibration of your outer hair cells, occurring when there is a kind of stimulation in your cochlea.

However, 60 decibels is the normal speech and shouting in the ear begins at 80 decibels. Adults having hearing loss up to 25 decibels, usually have normal hearing. If your hearing test show 26 to 40 decibels, then you might be having mild hearing loss. Similarly, if the results show 41 to 55 decibels then there is moderate hearing loss. For moderate to severe hearing loss, the hearing loss test would show 56 to 70 decibels. The hearing test results will show 71 to 90 decibels if you have severe loss of hearing. However 91 to 100 decibels show profound hearing loss in you. You doctor will diagnose your hearing condition and treat you accordingly based on your hearing loss test results.
