Imagine being in a room full of people – a cacophony of conversations and noise. Despite standing right next to someone, you strain to hear her voice.
People who use hearing aids often struggle to focus on one voice – especially in noisy environments. They could crank up the volume on their hearing aids – but that would also crank up the volume of everything else in the background.
Professor Neal Hall and his group of graduate students from the Cockrell School of Engineering at the University of Texas offers a solution: a device that mimics the hearing powers of a fly.
