At one point, the narrative (2021) landed on this native insect whose frequency was so loud that you could "hear it from inside a car while driving [40+] mph down the highway" (paraphrased).
Was this debunked or just another conspiracy™?

> The heavily redacted report notes that “many” of those reporting symptoms described hearing “unusual sounds” but states that in only one instance someone experienced medical symptoms immediately after hearing the sounds. The report goes on to say that JASON could identify “no plausible single source of energy (neither radio/microwaves nor sonic) [that] can produce both the recorded audio/video signals and the reported medical effects.”
Instead, the scientists wrote that the most likely source of the sound heard in the recordings is the Indies short-tailed cricket, whose call, it says, “matches, in nuanced detail, the spectral properties of the recordings from Cuba.” Still, the report hedges, saying that “other hypotheses are plausible,” including that the sounds were created by a mechanical device or “structure-borne vibrations.” [0]
