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

mechanical, hydraulic and electrochemical energy. The integration laser Doppler vibrometry and micro-CT scanning allowed us to identify the auditory vesicle and to conclude that the process relies on a tympanal lever system analogous to the mammalian ossicles. This serves to transmit air-borne vibrations to the fluid (the auditory vesicle), and also on the mechanoreceptors. Therefore the bushcricket ear performs the crucial stage of air to liquid impedance conversion and amplification just as in a mammal's ear."

In mammals, hearing relies on three canonical processing stages: an eardrum collecting sound, a middle ear impedance converter and a cochlear frequency analyser. The katydid ear performs these steps in the hearing process, something previously unknown in insects. The discovery of the impedance conversion and amplification mechanisms is a huge step forward in understanding the mechanisms of hearing processes in insects. This level of sophistication, sensitivity and functionality of insect hearing could be transferred into engineered bio-inspired systems. For instance, the ears of some bushcricket species are remarkably sensitive and can detect extreme ultrasonic signals (>130 kHz) at long distances. Such performance and sensitivity would have the potential to inspire engineers in the design and construction of acoustic sensors and actuators.

Dr Montealegre-Z plans to further his research to study the ears of species of the genus Arachnoscelis which use extreme ultrasonics (130 150kHz) in order to find out how bushcrickets are able to hear each other's high pitched sounds from long distances.

He said: "These results were obtained on a single species, C. gorgonensis, which uses moderate ultrasonic frequencies of 23kHz. However, we have measured other species and have discovered a bushcricket species in the rainforests of South America, which emits sounds at 150kHz. Sounds at these frequencies suffer excess attenuation and would not
