Research on VoIP then led to research on tinnitus (go figure!)
Tinnitus may be the resulting changes to neurons in the brain associated with hearing, after hearing degradation (often caused by loud noises). And such neuronal changes may involve the neurotransmission chemcials Glutamate and GABA. These articles are a good starting point for considering brain-neuron-focused therapy to cure (or reduce) tinnitus; at least such research seems to be making progress in understanding this very complex tinnitus that affects "nearly 20% of the population" (re: ncbi article):

"Experiments over the past 30 years, including important research by Merzenich, have shown that the brain is plastic enough to reorganize in this way when it loses sensory input."
"Hearing loss causes changes at junctions between nerve cells, the so-called synapses, that both excite and inhibit firing. His experiments showed that tinnitus is correlated with lower levels of the inhibitory neurotransmitter GABA (gamma-aminobutyric acid), but not with changes in the excitatory neurotransmitters."

"1. Glutamate and GABA These two chemicals account for 80% of brain activity. They work to counteract each other. Glutamate accelerates brain activity and GABA puts the brakes on it. Glutamate is excitatory and GABA is inhibitory."
"Nutritional support for Glutamate and GABA includes: the amino acids taurine, GABA and L-theanine, the antioxidants NAC (N-acetyl cysteine) and green tea, vitamins B6 and D, minerals magnesium and zinc, and omega-3 fatty acids."
"One of the current, prominent hypotheses of tinnitus development is that, after being triggered by peripheral injury, tinnitus may result from a maladaptation of the central auditory system to this peripheral dysfunction (Auerbach et al., 2014), and that one of the mechanisms by which this occurs is a decrease in inhibitory neurotransmission."

"If you have had it for years, the chance for a cure is unlikely."
Apparently the reality, especially if neuronal plasticity is now the cause of ringing (audio neurons have adapted to the original cause). But this same plasticity may simply indicate that a cure is complex and slow to achieve, since audio neurons don't reconfigure quickly ... and how to nurture this reconfiguration is unknown.

Wow! The brain's old neurons need a redo ... and the evolutionary brain is wired to this!
(probably while we're sleeping 8 of 24; less than 8 and we might not be stylin' up there)
If tinnitus is not corrected with such redo, this might imply that those neurons are now "keepers"
... or that the problem is occuring before those neurons cause the brain to hear this noise ... or ?
