Very interesting!
So, if I understand correctly, will we have over-the-counter hearing aids capable of covering even severe/profound losses? Maybe even self-regulating?
Wow! It will be a real revolution! Even superpower hearing aids will be less size! Cannot wait!
Looks good: what’s the current draw/life like with an actual hearing aid doing proper processing?
Is the only application with larger batteries?
Will we have all the superpowers of the XMen? 
Apparently they have already made the first hearing aid, but it doesn’t seem that small to me:

It will take time.
I read about the MEMS technology about 4-5 years ago in Silicon Chip (Australian electronics magazine) and think it has a lot of potential but thought it would have progressed further by now. Still, something I will be keeping an eye on.
