How male sound pressure level influences phonotaxis in virgin female Jamaican field crickets (Gryllus assimilis) [PDF]

open access: yesPeerJ, 2014
Understanding female mate preference is important for determining the strength and direction of sexual trait evolution. The sound pressure level (SPL) acoustic signalers use is often an important predictor of mating success because higher sound pressure ...

Numerical Simulation of Acoustic Wave Generated by DC Corona Discharge Based on the Shock Wave Theory

open access: yesApplied Sciences, 2023
The audible noise generated by corona discharge has the N-type characteristic at the initial generation stage, and it is a typical shock wave. This shock wave usually only exists around the corona source with a tiny range, making it difficult to obtain ...
