In a groundbreakingstudy conducted by researcher at Tel Aviv University , plant have been found to give out trenchant supersonic sounds when under stress . These click - similar sounds are similar in volume to human speech but happen at high frequencies beyond the human hearing range . The findings suggest that the audio bring forth by plants may be detectable by various animals such as bats , black eye , and insects .
The subject , led by Prof. Lilach Hadany from the School of Plant Sciences and Food Security at the Wise Faculty of Life Sciences , and Prof. Yossi Yovel , Head of the Sagol School of Neuroscience , focus chiefly on tomato and tobacco plants . Wheat , corn , cactus , and Lamium amplexicaule were also included in the study . Researchers subjected the plants to various treatments , including dehydration and stem injury , to determine if the plant ’s condition affect the audio utter .

Using ultrasonic microphone and machine learning algorithms , the squad discovered that unstressed plants produced less than one audio per hr on ordinary . In contrast , stressed plants emitted twelve of sounds every hour . The algorithmic rule were able to identify the plant and fix the type and story of stress establish on the recordings , even in a noisy greenhouse environment .
About the Study
Prof. Hadany explain , “ Our finding suggest that the world around us is full of plant life sounds , and these sound contain information – for example , about water scarcity or injury . ” The research team plans to continue exploring the mechanism behind plant voice and how other organisms , including plants themselves , may detect and react to them .
The finding have been published in the honored scientific daybook Cell . This study has dissolve a long - standing scientific controversy by proving that plants do emit audio . According to Prof. Hadany , “ In this study , we resolved a very quondam scientific contention : we proved that plants do emit sound ! Our findings suggest that the human beings around us is full of flora sounds , and these sound stop info – for model , about water scarceness or combat injury . ”
The researchers believe that these supersonic sound emitted by plants could be utilitarian not only to animal in nature but also to man . With the development of appropriate tools and sensors , growers could potentially use this information to determine when plants need watering or are under stress .

In their future study , the researchers aim to cut into deep into the intriguing world of plant sound . They plan to search various question such as the chemical mechanism behind flora sounds , how moth detect and react to sounds emitted by plants , and whether other flora can hear these sounds .
This groundbreaking research spread up a new understanding of plant life communication and has possible app in Agriculture Department and environmental monitoring . As Prof. Hadany states , “ evidently , an idyllic field of flowers can be a rather noisy place . It ’s just that we ca n’t hear the sounds ! ”
