Scientists suspect the sounds that once were thought to be the cause of the mysterious "sonic illness” affecting diplomats in Cuba were probably crickets, specifically the noisy mating call of male Indies crickets. If you think crickets couldn't possibly make that much noise, note this from an article on the subject in the New York Times:
“Mr. Stubbs recorded short-tailed crickets while in Costa Rica, and he found their songs overpowering. “They’re incredibly loud,” he said. “You can hear them from inside a diesel truck going forty miles an hour on the highway.”
Stubbs went on to say the cricket chirps may have been wrongly associated with whatever may be causing the medical problems diplomats have suffered.
“It’s entirely possible that they got sick with some other completely unrelated thing that was not a sonic attack, or that they were targeted in some other way.”
Of particular interest to me, a guitar picker and singer of songs, was this:
“Male singing insects produce regular patterns during courtship. Females are attracted to certain males based on their songs, which has led to the evolution of different songs in different species.”
Turns out, humans are not so different from insects, as we might like to think. Hell, there once was a bunch of humans who called themselves The Chirping Crickets:
