Kind Of Hearing Tests - Rehabilitation Center for Hearing Impaired
The various tests that performed at Rehabilitation Center for hearing loss include:
Site of lesion testing
An audiogram is a hearing test that is generally performed in a soundproof room at Rehabilitation Center using sophisticated, calibrated equipment.
A trained professional, most commonly a certified audiologist, usually administers the test. Earphones are placed over the person’s ears, and tones are presented to each ear, one at a time. The softest level at which the sounds can be heard is recorded.
Tympanometry is a common test that involves placing a gentle pressure probe in the ear. This test assesses the pressure in the middle ear, and it may help detect fluid, problems with the middle ear bones, and other conditions
Site Of Lesion Testing
Site of lesion testing involves the regular equipment used in an audiogram, with a variety of other tests to help determine where a problem lies. This kind of testing may involve:
Comparing the hearing in one ear with the other
Detecting small changes in signal intensity
Testing ability to hear in the presence of noise
Testing the ability to hear sentences placed in both ears at the same time
Brainstem evoked response audiometry (BERA or ABR) involves sophisticated, computerized equipment. Sounds are placed in the ear, and the brainstem’s response is recorded from electrodes (similar to electrocardiogram electrodes) that are taped to the patient’s head. This testing is extremely helpful in:
Distinguishing sensory (inner ear) from neural (nerve) causes of hearing loss
Helping to localize problems in the brainstem auditory pathway
Determining the ability to hear soft sounds, in selected cases
