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.
Figure 1. The Ear. Hearing can be impaired due to lesions in the external ear canal, the middle ear, or the inner ear. The purpose of hearing testing is to evaluate hearing function and, if it is impaired, to attempt to localize the site of lesion. What is Hearing Testing? Hearing testing is a means of evaluating an individualâs overall hearing function. The tests are used to determine if there is something wrong with the hearing (auditory) portion of the inner ear. They are often used as an initial screening to decide if more expensive tests like magnetic resonance imaging (MRI) are needed.
