Mr. Stubbs suspected that this mismatch might be an artifact of the recording itself. Diplomats made their recordings inside houses, while biologists have recorded the crickets in the wild.
So Mr. Stubbs played the cricket recording in a house. As the calls bounced off the walls, they echoed in a pattern similar to the irregular pulses heard on the Cuban recording.
The song of the Indies short-tailed cricket “matches, in nuanced detail, the A.P. recording in duration, pulse repetition rate, power spectrum, pulse rate stability, and oscillations per pulse,” the scientists wrote in their analysis.
Experts on cricket songs said the analysis was well done. “It all seems to make sense,” said Gerald Pollack of McGill University, who studies acoustic communication among insects. “It's a pretty well supported hypothesis.”
