Question
The sound produced by a bat is
–Solution
Although bats use echolocation to detect their prey, and find their way around in the dark, the sounds which they emit are 'ultrasonic', which is another way of saying they are beyond the range of normal human hearing. Ultrasound is a cyclic sound pressure wave with a frequency greater than the upper limit of the human hearing range. Ultrasound is thus not separated from "normal" (audible) sound based on differences in physical properties, only the fact that humans cannot hear it.
