On This Page. Viral meningitis is the most common type of meningitis, an inflammation of the tissue that covers the brain and spinal cord. It is often less severe than bacterial meningitis, and most people get better on their own (without treatment).
Sound level calibration is a prerequisite to properly measuring hearing loss. Our hearing test is the only online hearing test we know of that offers you a way to calibrate your headphones or speakers, giving you the opportunity to reliably estimate your hearing loss. Use our test with confidence to confirm normal hearing, or a mild, moderate, or severe hearing loss. This test-like any other hearing test-requires a decent pair of headphones (good speakers will work too, although headphones are preferred), and a quiet environment.
Auditory brain-stem response (ABR) testing: Electrical nerve impulses that carry the sound from the inner ear to the brain are measured. Electrodes are placed in the ear canal and on the head, and short clicking sounds are turned on.ost people with a sensory hearing loss find that hearing aids are beneficial. Neural hearing loss: occurs when there is damage to the hearing nerve or the nervous system. The inner ear generates neural impulses that travel through the hearing nerve to the brain.
