>vocal emission frequency used by large moths when echolocating a mate
"Females showing calling behavior ceased this behavior in response to bat echolocation calls, a startle response exhibited by the females24. We examined whether conspecific male songs also interrupted the females' calling behavior. The majority of females (>73%) stopped exposing the pheromone gland in response to all sound stimuli broadcast at high sound pressure levels (>74 dB) (Figure 2C–F). FM and CF bat calls had the same level of effect as the male song (LRT in GLM, p = 1.00 and p = 0.34), while a 40-kHz sine-wave tone was significantly less effective (p = 0.023)"
