Effective communication is more than good hearing, and good hearing is more than amplified noise. Despite all of the dedicated research, the exact mechanisms behind hearing loss remain mysterious; but a New York hearing loss study might have peeled back the veil a tiny bit.
The study used a species of mouse, the CBA, that gradually lost its ability to hear higher frequencies over time – like humans.

To increase the yield, researcher Robert Frisina cross-bred them with a more virile sort of mouse, C57 Black 6 – known for their poor hearing.
The results were startling.
