Dr. Shore's device won't work for everyone
Not to be a Negative Nelly, but I truly think it won't help everyone, at least to an extent. While I appreciate the perspective, I would like to point out that Susan Shore's research takes into account the critical role of trigeminal somatic crossfire in determining the severity of tinnitus. This is a crucial aspect that is often overlooked when discussing the efficacy of the device. While fusiform cells in the DCN are a very important factor, it's not mutually exclusive.
"The trigeminal and dorsal root ganglia relay afferent somatosensory information from the periphery to secondary sensory neurons in the brainstem, specifically, the spinal trigeminal nucleus and dorsal column nuclei, respectively. Each of these structures has been shown to send excitatory projections to the cochlear Nucleus." (Neural mechanisms underlying somatic tinnitus Susan Shore et al. Prog Brain Res. 2007.)
Massively decreasing hyperactivity/excitatory signals and crossfire of the Nucleuses (DCN, HCN, TGN, etc) is what can lead catastrophic tinnitus to become mild, to the point of it being a non-issue as well.
Due to the device having electrical stimulation, I believe that this provides neuronal activation by external electrical stimulation is governed by voltage-gated ion channels. Hence:
"Activation of metabotropic (P2Y) purinergic receptors by ATP increases type II afferent excitability by the closure of KCNQ-type potassium channels. Thus a noise-induced hyperexcitability of type II fibers, due to the closure of KCNQ channels, may underlie the increased sensitivity or intolerance to sounds that are normally not perceived as loud, which is a hallmark of hyperacusis. Alternatively, this mechanism may also be involved in hyperacusis with pain (noxacusis)."
I do not, however, think that this device will "give us silence". But after 2 years of 70+ dB tinnitus, living with a quiet room hiss/squeak would be a blessing. I also believe this device has the potential to "cure" hyperacusis as well, or massively suppress it to a point of it being a non-issue.
Not everyone has these somatic co-factors, hence why I believe the device won't massively benefit everybody (non somatic tinnitus to be precise).
