Scientists have recorded the sound of plants making noise when they are disturbed, which could be heard over a meter away. This discovery suggests that plants might communicate through sound when they experience stress or changes in their environment.
According to a study published in Cell by researchers at Tel Aviv University, plants emit a popping or clicking sound in ultrasonic frequencies when they are stressed. This sound intensity increases as the plant experiences more stress, indicating a potential method of communication for plants.

Scientist Lilach Hadany explained that while humans can’t hear these sounds, they could be crucial for other organisms like insects. The study observed tobacco and tomato plants in stressed and unstressed conditions, finding that only distressed plants made noticeable noises.
Although it’s still unclear how plants produce these sounds, this research sheds light on the complex ways in which plants respond to their environment.
