Navy to Create Better Remote Sensing Techniques using Cicadas’ Acoustic Abilities
Cicadas' unique acoustic abilities are now being studied by the scientists in order to develop new remote sensing techniques and ways to communicate while being underwater.
Scientist said that though they have understood the mechanisms behind their sound making, imitating those is a tough task. Derke Hughes, a Researcher at the Naval Undersea Warfare Center in Newport, R. I, said that he was working on a physics-based model to find out how these insects produced mating calls.
This model will help the researchers in understanding how loud noise can be produced using very little power. Hughes said that these insects have very unique capability to deform their bodies as they produce this vibration.
Their bodies undergo squeezing and releasing at a rate as high as 300 to 400 times a second. The research will be presented by Hughes and his colleagues at the International Congress on Acoustics in Montreal. The findings will have applications for remote sensing underwater and in the rescue operations.
These insects bites don't bite or sting, avowed the Department of Energy and Environmental Protection (DEEP). Also, they affirmed that these do not pose any threat to the garden planting and trees. They spend over 17 years underground before they emerge over ground.
