Tinnitus is the perception of sound (ringing, hissing, buzzing) in one or both ears, not produced by an external source. It is a common complaint, affecting approximately one in six Americans. It ranges in severity from a mild background noise to a constant disabling disruption of daily function. Some cases begin following known stresses such as loud noises or medications, but many times the causes are unknown.
Many people sensitive to non-ionizing electromagnetic fields describe various ear sensations -- heat, throbbing, pain -- as well as tinnitus. Some studies have been performed and several mechanisms suggested. This map offers a linked overview of reports, mechanisms, studies and articles.
