Same, plants, same.
A group of researchers from Tel Aviv University in Israel discovered that plants make noise when they are “stressed.” These sounds cannot be heard by humans even though they are emitted at a volume similar to human speech. This is because they are at such a high frequency that we can’t hear them.
What’s funny though is that when the researchers recorded and analyzed the sounds, it sounds like either someone is clicking their mouse too fast or someone’s popcorn is popping. The researchers also shared that each plant and each type of stress has its identifiable sound. “While imperceptible to the human ear, the sounds emitted by plants can probably be heard by various animals, such as bats, mice, and insects,” the researchers said.
