Tinnitus is usually subjective, meaning that the sounds the person hears are not detectable by means currently available to physicians and hearing technicians. [3] Subjective tinnitus has also been called "tinnitus aurium", "non-auditory", or "non-vibratory" tinnitus. In rare cases, tinnitus can be heard by someone else using a stethoscope.
Though the pathophysiology of tinnitus is not known, noise exposure can be a contributing factor, therefore tinnitus can be associated with hearing loss, generated by the cochlea and central nervous system (CNS). High frequency hearing loss causes a high pitched tinnitus and low frequency hearing loss causes a roaring tinnitus. [19] Noise ...
Over time, the brain becomes accustomed to hearing the sound it 'craves' and the tinnitus sound can lessen as a result. Some patients like to use white noise machines or specialized tinnitus sound ...
The cause is thought to be thermoelastic expansion of portions of auditory apparatus, and the generally accepted mechanism is rapid (but minuscule, in the range of 10 −5 °C) heating of brain by each pulse, and the resulting pressure wave traveling through the skull to the cochlea. [5]
The psychological basis for TRT is the hypothesis that the brain can change how it processes auditory stimuli. TRT is imputed to work by interfering with the neural activity causing the tinnitus at its source, in order to prevent it from spreading to other parts of the nervous systems such as the limbic and autonomic nervous systems.

Thalamocortical dysrhythmia (TCD) is a theoretical framework in which neuroscientists try to explain the positive and negative symptoms induced by neuropsychiatric disorders like Parkinson's Disease, neurogenic pain, tinnitus, visual snow syndrome, schizophrenia, obsessive–compulsive disorder, depressive disorder and epilepsy.
It is typically experienced as a secondary symptom of sensorineural hearing loss, although not all patients with sensorineural hearing loss experience diplacusis or tinnitus. [ 1 ] [ 2 ] The onset is usually spontaneous and can occur following an acoustic trauma , for example an explosive noise, or in the presence of an ear infection . [ 3 ]
Ototoxicity of gentamicin can be exploited to treat some individuals with Ménière's disease by destroying the inner ear, which stops the vertigo attacks but causes permanent deafness. [19] Due to the effects on mitochondria, certain inherited mitochondrial disorders result in increased sensitivity to the toxic effects of aminoglycosides.
