Mosquito acoustic communication is studied for its singular and poorly-knownin-flight hearing mechanism, for its efficiency in mechanical-to-acousticalpower transduction, as well as for being the deadliest disease vector. Acombined computational and experimental methods to predict and extract thewing-tone sound from individual tethered or free-flying mosquitoes wasdeveloped. This paper describes the experimental methods and gives somepreliminary results of the simulations. Simultaneous slow-motion images (20kfps) and 3D-sound of Culex quinquefasciatus mosquitoes were recorded. The soundmap around the mosquitoes was recorded in one or two planes with a rotatingarray of 12-microphones. Backilluminated mosquito-wings allowed to extract 11veincrossing locations on each high-speed camera image over 3-4 wingbeatperiods to generate 3D deformations of the wing. Simultaneous 3D sound datarecorded by microphone arrays were post-processed by using the physicsbasedindependent component analysis to filter out the noise and generate a 3D soundmap. The simulated wingtone sound pattern generated from the aeroacousticsimulation agrees well with the original recording in the experiment using themicrophone array. The methods we developed will allow us to investigate thewing-tone soundscape of individual mosquitoes during the courtship andmate-chasing.
