How do hearing aids work? And are they being developed?
November 11th, 2011obviously nowadays young people listen to loud music for long periods of time (me included) and we are damaging our hearing. when the loud noise damages or kills some of the cells in the ears how do hearing aids work to improve hearing?
are scientists developing anything better? in a few years there are going to be so many more people needing hearing aids so how are they doing with new technology/science on that, do we know?
thanks
