It is believed that these types of perception result from abnormal neuronal activity at a subcortical level of the auditory pathway.6,8, The pattern characterizing tinnitus is related to the library of patterns stored in auditory memory and also, via the limbic system, associated with emotional states.9 The characteristics of tinnitus are generally unrelated to the type or severity of any associated hearing impairment, and thus the latter offers little diagnostic value.6 Most tinnitus patients match their tinnitus to a pitch above 3 kHz.10 The tinnitus characterizing Meniere's disease, described as roaring, matches a low-frequency tone that is usually from 125 to 250 Hz.11 However, tinnitus in the advanced "burned-out" stage of Meniere's disease is often higher in pitch and tonal in quality.12, Most patients with both tinnitus and hearing loss report that the frequency of the tinnitus correlates with the severity and frequency characteristics of their hearing loss, and that the intensity of the tinnitus is usually less than 10 dB above the patient's hearing threshold at that frequency.6 Some patients who have central auditory processing disorders and have difficulties understanding speech in noise report experiencing tinnitus even though their pure-tone audiometric thresholds are normal.8,13, Less prevalent forms of tinnitus, such as those involving well-known musical tunes or voices without understandable speech, occur among older people with hearing loss and are believed to represent a central type of tinnitus involving reverberatory activity within neural loops at a high level of processing in the auditory cortex.8,14, Somatic tinnitus is a type of subjective tinnitus in which the frequency or intensity is altered by body movements such as clenching the jaw, turning the eyes, or applying pressure to the head and neck.15 Reports that tinnitus is louder upon awakening suggest the involvement of somatic factors, such as bruxism. These neurons receive inputs from the nearby spinal trigeminal tract, the fasciculus cuneatus, and the facial, vagal, and glossopharyngeal nerve fibers innervating the middle and external ears.49, Pain signals from the cochlea carried by the cochlear C fibers could also be interpreted by the CNS as tinnitus.58 It is further hypothesized that somatic tinnitus is due to central crosstalk within the brain, because certain head and neck nerves enter the brain near regions known to be involved in hearing.57, The aforementioned theories cannot explain why some people suffer from tinnitus while others do not.

This is the first time they might experience the feeling of being separated from their friends in preschool. An excessive curiosity of sorts could also manifest into frustration-filled behaviour. IHC damage prevents hyperactivity in the DCN.51, According to auditory plasticity theory, damage to the cochlea enhances neural activity in the central auditory pathway.52 Auditory plasticity emerges as a consequence of the aberrant pathway, and tinnitus might be considered to be the auditory system analog to phantom limb sensations in amputees.53 Tinnitus might be generated in the temporal lobe in the auditory association cortex54 and inferior colliculus.55 The ability of some individuals to modulate tinnitus by performing voluntary somatosensory or motor actions is probably attributable to plastic changes involving the development of aberrant connections between the auditory and sensory-motor systems in the brains of these patients.56, According to crosstalk theory, when auditory nerve fibers are intact and some other cranial nerves are damaged, artificial synapses (called crosstalk) can develop between individual auditory nerve fibers, resulting in the phase-locking of the spontaneous activity of groups of auditory neurons.

Indeed, the cause of somatosensory pulsatile tinnitus syndrome is not vascular, with the syndrome deriving from cardiac-synchronous somatosensory activation of the central auditory pathway or the failure of somatosensory-auditory central nervous system (CNS) interactions to suppress cardiac somatosounds.18 Pulsatile tinnitus superimposed on steady tinnitus could result from the pulsation of blow flow with the spiral capillary of the basilar membrane.19, The most common associated symptoms or subjective discomforts involve concentration difficulties, insomnia, and decreased speech discrimination.20 The annoyance of tinnitus is not correlated with the acoustic characteristics, but there is a significant correlation with psychological symptoms.21 The difference between simply perceiving tinnitus and being annoyed or distressed by it depends exclusively on the activation of the limbic and autonomic nervous systems.8 Most patients with significant tinnitus have difficulty falling asleep due to the accompanying anxiety, which also causes difficulties in returning to sleep during periods of wakefulness during the night.8, There is pronounced neuronal activity in the auditory pathways during sleep due to the auditory system continuously monitoring the sound environment.8 Common detrimental activities and/or conditions include noise exposure, being located in a quiet place, emotional stress, loss of sleep, and physical exhaustion.22 Annoyance, depression, and interference with sleep are more common and the tinnitus is louder in patients with Meniere's disease than in those with tinnitus deriving from other etiologies.22 Furthermore, the successful control of vertigo in patients with Meniere's disease can lead to them focusing more on their tinnitus and hence becoming more distressed by this condition.12, The strength of the reaction to tinnitus is therefore determined by its significance and by past experience-the actual intensity and characteristics of the sound are of secondary importance.23, Noise-induced tinnitus can be acute or chronic.

Such compression and consequent ephaptic coupling might lead to tinnitus if synchronization of the stochastic firing in the cochlear nerve is perceived as sound.57, The activity of the DCN is also influenced by stimulation of nonauditory structures;47 however, the somatosensory system is the only nonauditory sensory system that appears to be related to tinnitus (e.g., in temporomandibular-joint syndrome and whiplash).49 Somatic tinnitus can develop from activation of latent oto-somatic interaction.16 Somatic (craniocervical) tinnitus, like otic tinnitus, is caused by disinhibition of the ipsilateral DCN, which is mediated by nerve fibers whose cell bodies lie in the ipsilateral medullary somatosensory nuclei.

WebDiscover articles and insights by Ed Stetzer, Ph.D. on ChurchLeaders.com. It is proposed that all levels of the nervous system are, to varying degrees, involved in tinnitus manifestation.1,31, Spontaneous otoacoustic emissions (SOAEs), first discovered by Kemp,32 are small acoustic signals presumed to be generated by the electromotile activity of the OHCs of the cochlea and propagated into the external auditory canal.33 SOAEs produced by the cochlea can be perceived as tinnitus.34 SOAEs are usually inaudible, but they can become audible due to instability.35 These atypical SOAEs are much more prevalent in the higher frequency range and can appear at sound pressure levels up to 55 dB SPL in the ear canal.36 Tinnitus due to SOAEs is mild and is more common in subjects with normal hearing and in those with only middle ear disorders.37 SOAEs decrease as hearing loss progresses, and hence these otoacoustic emissions are not likely to cause tinnitus when a hearing loss of 35 dB or more is present.38 However, SOAEs cannot fully explain the mechanism of tinnitus since aspirin largely abolishes SOAEs without improving tinnitus.39, Edge theory, also known as contrast theory, proposes that tinnitus is induced by increased spontaneous activity in the edge area,40 which represents a transition from OHCs in the organ of Corti with relatively normal morphology and function on the apical (i.e., low-frequency) side of a lesion to OHCs toward the basal side that are missing or have a pathologic appearance and poor functionality.19 Edge theory can be explained by discordant theory.9, According to discordant theory, tinnitus is induced by the discordant dysfunction of damaged OHCs and intact inner hair cells (IHCs) of the organ of Corti.
