The Noisy Truth About Stressed Plants
TL;DR Summary
Plants emit ultrasonic sounds when they are thirsty or stressed, according to a study by Tel Aviv University scientists. The researchers used microphones to record the sounds produced by tomato and tobacco plants in a sound-protected box and a greenhouse. They developed machine learning models to identify the condition of the plants based on the detected sounds. The study suggests that humans could use this information to determine when plants need watering. However, scientists caution that there is no evidence that the sounds produced by plants are a form of communication.
