Range of theories from loss of outer hair cell function to increased spontaneous activity of central nerves
Can be generated from any part of the auditory system from the ear to the Central Nervous System (CNS)
This then may become modified by the CNS
Patients with tinnitus exhibit enhanced auditory sensitivity
Patients with tinnitus exhibit enhanced auditory sensitivity
This is caused by hyperactivity of the auditory central nervous system
In patients with tinnitus and hearing loss, the tinnitus pitch and the hearing loss frequency spectrum are usually matched
The decreased input from the cochlea, due to outer hair cell damage, results in readjustments in the central auditory system resulting in abnormal neural activity including hyperactivity, bursting discharges and increases in neural synchrony.

When the perception of tinnitus is associated with negative reinforcement, the autonomic nervous system is activated.

Physiological and psychological reactions then lead to enhancement of the tinnitus signal

Reports of the use of hearing aids in the management of tinnitus go back over 60 years

Because hearing loss is often associated with tinnitus, at least partial restoration of hearing should help to reduce the central gain in auditory perception that is a feature of tinnitus
A recent scoping review of studies of hearing aids in tinnitus revealed that 17/18 publications showed improvements in tinnitus symptoms by fitting hearing aids

No approved drugs (European Medicines Agency [EMA] or US Food and Drug Administration [FDA])
Some psychopharmacological agents may help reduce the severity of psychological issues associated with tinnitus, and some may also lessen tinnitus symptoms
