These monitors and instruments may not look like much, but they could help change the way people hear. This technology could improve on hearing aids currently on the market.
By putting multiple microphones in a smaller area, you can reject, noise coming from 360-degrees however, then those microphones need to be very precise.
The engineering researchers here at Arizona State University say developing a better hearing aid isn't an easy task. Size matters...
You want to make everything small, that you can fit inside a canal which is about an inch long, and .7 inch in diameter for adult case. So, imagine that you want to put microphone, circuits, battery, speaker, everything packaged in that size. Wow, it's challenging, yes.
Once the tiny microphones and speakers are developed, the next step is to make the device more comfortable.
What we are trying to achieve here is, can we make them like a sponge, where you can basically fit it in your ear, when they're really small and it expands.
The device is in the very early stages but these engineers are optimistic.
One of the satisfaction as an educator is look at the people as they are happy and if I just imagine that those people are happy with our technology that'd be just wonderful.
And it sounds like they're on the right track. For WebMD, I'm Damon Meharg.
