Sound Source Segregation in the Acoustic Parasitiod Fly Ormia ochracea
… signal features that the acoustic parasitoid fly Ormia ochracea (Diptera: Tachinidae) evaluate for host cricket song recognition. With flies subjected to a no-choice paradigm and forced to track a switch in the broadcast location of test songs, I describe several response features (distance, …

Testing and characterization of second-order differential microphones
… designed based on the ear of the fly Ormia ochracea. The response of these microphones is modeled as a linear combination of the gradients of the sound field. A least squares approach is employed in order to determine the transfer functions between the response and these gradients. …

Toward a micro-scale acoustic direction-finding sensor with integrated electronic readout
… acoustic direction-finding sensor based on the Ormia ochracea fly’s ear. First, linear elastic stiffness models are presented and then validated by using a nanoindenter to measure the sensor’s stiffness directly. The measured stiffness is highly linear, and the resonant frequencies are correctly …

FLY-EAR INSPIRED MINIATURE SENSOR SYSTEM FOR TWO-DIMENSIONAL SOUND SOURCE LOCALIZATION
… hearing mechanisms of a particular fly, known as Ormia ochracea. Background research into the hearing mechanisms of the fly found that it can accurately locate a sound source even though its eardrums are separated by a distance of only 500 μm. The fly's exceptional directional hearing capability …

Understanding and Mimicking the Fly's Directional Hearing: Modeling, Sensor Development, and Experimental Studies
… organ separation of only 520 µm, the fly Ormia ochracea is found to exhibit remarkable ability to pinpoint its host cricket at 5 kHz. The key to this fly's phenomenal directional hearing ability is believed to be the mechanical coupling between the eardrums. This innovative solution can …
