Acoustic-Structure Interaction Simulation of a Differential Phase Sensor
The idea of application as a hearing device based on a parasitoid fly, Ormia ochracea has been studied extensively recently. This paper addresses another possible application as an underwater directional sensor.
In order to study the feasibility of the application, it is necessary to investigate the feasibility of the underwater application of the directional sensor based on the hearing system of the parasitoid fly. Placing a sensor in water causes fluid loading to the sensor. In this paper, the half-power bandwidth method is used to estimate the radiation damping ratio based on the corresponding Q value from the frequency response function of a sensor which is excited by far field sound wave impinged on the sensor.
