Wow…exciting research into hearing loss:
“A new report suggests it might be possible to change the circuitry of the brain to better process sound, a finding that could give renewed hope to the 350 million people worldwide who suffer from hearing loss.

Patrick Kanold, an expert on how the brain processes sound and co-author of the new study published in Neuron, says a child’s brain is malleable enough to rewire some circuits that process sensory information.  ”

“Kanold says while the rodents’ sharper hearing reverted back to normal within a few weeks, the experiment demonstrated the adult brain may be less hard-wired than previously thought. By temporarily preventing vision, Kanold says, it may be possible to change the brain circuitry to better process sound.”
