typers of tinnitus

The word “tinnitus” comes from the Latin and means “to ring/ringing” or “to sing loudly”. It is used to describe sounds which are perceived, but which have no actual acoustic signals from the surrounding environment and which have no meaning for the sufferer. Tinnitus can divided into various types by different criteria.
According to its ability to be perceived by an external examiner, we can differentiate between:
Objective Tinnitus: The sounds can also be heard by an external examiner and are caused by a vascular or muscular disorder. Objective tinnitus is rare. Subjective Tinnitus: Only the sufferer can hear the sounds. This is much more usual.

acute, subacute and chronic tinnitus

Different types of tinnitus can be distinguished according to their lifespan:
Acute Tinnitus: lasts less than three months Subacute Tinnitus: lasts between four and six months Chronic Tinnitus: lasts longer than six months

compensated and decompensated tinnitus

We can further distinguish between two distinct types of tinnitus according to the effects reported by the patient: Compensated Tinnitus: The patient registers the sounds, but can cope with them so that they cause little or no psychological strain. The patient’s quality of life is not substantially affected. Decompensated Tinnitus:
“Decompensated Tinnitus” is the most severe form of tinnitus. The sufferer hears sounds caused by "interference" in the brain’s hearing system. The tinnitus has become uncontrollable.This interference is caused by the brain trying to use other sounds to drown out those originating in the inner ear. If emotional overlay and stress cause this "interference" to become excessive, constant activation of the "interference" in sections of the temporal lobe of the auditory cortex and "decompensated tinnitus" will result.
Even when, therefore, the cause in the ear ceases to exist, the central closed-loop continues. This kind of tinnitus is also known as “centralised tinnitus“, and it works on the same principle as the “phantom pain” which is often experienced by amputees.
Tinnitus causes enormous problems for the sufferer. The noises in the ears cause sleep and concentration problems and lead to depression. There is a high level of psychological strain, and the patient’s quality of life is severely impaired.
Tinnitus may occur to any conceivable degree between the two extremes of "acute, compensated" and "chronic, decompensated".
