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.
Hearing is assessed using our state-of-the-art otogram to determine the type and severity of hearing loss. The otogram is an automated hearing test that evaluates the frequency range, intensity levels, speech discrimination, and the softest speech sound registered by the patient's hearing capabilities. The patient is asked to respond when a sound is heard, and testing typically takes less than 30 minutes.
