"It's so far off the scale of what we know that it's like we're observing 'Jedi' rats," says Mercado. "It almost seems like magic."
Vibroacoustics, or artificially produced ultrasonic vibrations, cause airborne particles to cluster, leading Mercado to suggest that rodents are using USVs to create odor clusters enhancing the reception of pheromones (chemical signals), thus making it easier for the vocalizer to detect and identify friends, strangers, and competitors.
