From the above report:
Studies show hearing loss can go hand-in-hand with over-excitable nerves within brain areas that process sound.
This uncontrolled nerve activity causes the noises that plague people with tinnitus and appears to be down to gene changes, Neuroscience reports.
And it raises the hope of treatment by silencing nerve activity, experts say....
Indeed, Belgian neurosurgeon Dirk De Ridder has tried implanting electrodes directly into the brain of sufferers to permanently normalise the overactive neurons.
He has had some successful results, although one of his patients repeatedly reported an out-of-body experience as a side effect.
