Discovery could hold the key to super-sensory hearing
Date:11/15/2012

transmit far in a rainforest environment, therefore limiting long-range communication. Yet they manage to listen to one another from far greater distances. We don't know how they do it, but we do think this sensitivity comes, in part, from the Auditory Vesicle. The University of Lincoln has an excellent team able to continue with this research, while also collaborating with partners at other universities. These findings change our views on insect hearing and open the way for designing ultrasensitive bio-inspired sensors."

Professor Daniel Robert is one of four academics at the University of Bristol's School of Biological Sciences who were part of the research team.

He said: "The ears of this bushcricket are teaching us that complex hearing mechanisms can take place in very small ears. As such we are learning how evolution has come up with very small, efficient and sophisticated microphones. We now have to learn how to make one like this."

Dr Montealegre-Z is planning field research to study katydids in their natural environment in Colombia (Natural National Park Gorgona) with colleagues from the universities of Graz in Austria, Bristol and Strathclyde. Funded by a National Geographic grant the study will entail connecting special electrodes to the katydid sensory system, which will then allow the scientists to hear the same sounds as the insects.

Dr James Windmill, from the Centre for Ultrasonic Engineering in the University of Strathclyde's Department of Electronic and Electrical Engineering, said: "Dr Montealegre's findings will make a valuable contribution to our search for the next generation of ultrasonic engineering technologies. By improving our understanding of insect hearing and sensory systems, we can incorporate new ideas and techniques into a wide range of technologies, including hearing aids, biomedical imaging systems for hospitals, and ultrasonic non-destructive evaluation to assess the structural integrity of bui
