Singing Rats

Loading audio...

Caption: Rats like those used in University of Illinois speech and hearing sciences professor Aaron Johnson's study make ultrasonic vocalizations (USVs) that are above the range of human hearing, but special recording equipment and a computer that lowers the frequency of the rat calls allows humans to perceive them. As the recording shows, the USVs sound a bit like bird calls.
