Abstract:

Dolphin click generators were studied via anatomy, tissue properties, physiology, and acoustic analyses. Our objective was to design, produce, and test computational models and physical devices that mimic dolphin sonar signal generation. Our multi-mass computational model of dolphin click production was based the Steinecke-Herzel model of the human larynx. We developed and implemented an acoustic model that translates the motions from our multi-mass model into acoustic signals. We also mastered CNC controlled milling machine and lathe operations to produce physical prototypes of biomimetic sound sources, complete with dolphin-like phonic lips and a pneumatic driver.
