Taming The Trolls Within

Tinnitus is a perception of a sound in one or both ears or in the head when no external sound is present. It is often described as ringing in the ears but also as hissing, roaring, whisthling etc. - but common to all - as a completely different sound as previously experienced from their external environment.It can be intermittent or continuus. It can accour as one time event, occassionaly or as long term symptom. Volume varies from subtle to shattering.Objective tinnitus has mostly physiological origin e.g. arterial anevrism in the brain. It is thereby only a symptom and not a disease itself. Treatment is with eliminating the cause.At subjective tinnitus abnormal auditory nerve activity is the only detectable change. This "true tinnitus" can be considered as a disease.What cannot be considered as tinnitus:-any external sound-sounds caused by change in external air pressure (at diving or quick changes in altitude (car on mountain road, plane...)-"voices" as psychiatric patients describe them.
