Apparently plants make sounds. We just can’t hear them. Scientists put microphones near various species of plants and found that sound comes off them when the plants are stressed. They sound like clicking or popcorn, but it’s at a frequency that’s too high for human ears. However, other animals like mice, bats, and insects likely can hear these sounds.
To run the tests, scientists placed plants in different situations from being in a box without light or sound to not watering them for a few days. Some had stems cut. Others had nothing done to them. The unstressed plants emitted a sound about once per hour. The stressed ones made about a dozen sounds per hour. Also, different plants make different sounds. How are they making sounds? Past experiments found that plants can make vibrations on their own. Researchers thing the vibrations are doing it.
I put a mic to the buffet at Golden Coral once. They lettuce was screaming, “You’re drowning us in all this Dorothy Lynch! Glub, glub, glub glub.” The greasy popcorn shrimp and ketchup flavored meatloaf were saying some profane things too.
