Gerbils Help Scientists Learn More About How We Hear

I ran across an interesting article today about how scientists used gerbils to learn about our sense of hearing.

Specifically, scientists studied the brain activity of gerbils as they distinguished between sounds of different pitches and frequencies. Scientists believe that this research can help them understand how we can pick out a single voice in a crowded, noisy room. They also believe that this research with gerbils may one day lead to the development of better hearing aids that can distinguish the sources of different sounds.
