Insects Help Researchers Blend Biology, Medicine and Engineering to Develop Better Hearing Aids
The human ear is a miracle of mechanical evolution. It allows us to hear an astonishing range of sounds and to communicate and navigate in the world. It’s also easy to damage and difficult to repair. Hearing aids are still large, uncomfortable and as yet unable to deliver the rich and wonderful sounds we take for granted. Yet there may be a new way for us to replace damaged hearing from an unlikely source – the insect world.
Spend a summer in the countryside in a warm climate and you’ll likely hear crickets chirping, males of the species “singing” in an attempt to attract a female. What’s surprising is how small the creatures are given the very high sound levels they produce. Could studying crickets allow us to learn something about how to design a small speaker that is also loud, just as you need for a hearing aid?
