The sharpest ear of all animals.

Taking a parallel with humans we only arrived at 20 kHz, and decreasing to 12 or less as we age, the dolphins for example only can reach 160kHZ. Scientists, not leave his astonishment and the results obtained may be used for the understanding of other sound elements, specifically on the Ultrasound in the air, according to Dr. James Windmill, from Strathclyde. Bats as it is already known, also using ultrasound, but this discovery positions to the moths of the wax in the first place, the bat is its natural predator, and therefore to survive had to develop these animals, more advanced forms of hearing and communication. The doctor Windmill is studying these animals for designing acoustic systems of low scale, to innovate technologically, for the creation of micro microphones.
