This book gives a thorough grounding in how hearing works, ear anatomy, causes of tinnitus, and possible treatments. According to the author, many experiences of tinnitus are not phantom sounds, but hypersensitivity to sounds created by your own body. For instance, humming might be caused by the movement of body fluids - blood travelling through the arteries. This can be caused by elevated blood pressure, and a wide variety of other possible causes. These are discussed, from noise, to stress.
