floors capable of emitting sounds which indicate their status. even everyone speaks in their own way language, as the sounds were found to be specific to each species. And they can also indicate their state health. This is a very interesting discovery that has just been published in Cell and put an end to the age-old dilemma.

For many years it has been intuitively assumed that plants can make sounds. This is because when using vibrometers, suspicious vibrations are detected around you. But did they correspond to acoustic waves? The truth is that people can’t hear them, but that doesn’t mean they don’t make sounds. Maybe they just don’t exist. frequency adequate.

This is exactly what the authors of this study, people from Tel Aviv University. Finally, they came to the conclusion that, as they suspected, they could indeed make sounds. They sound at the same volume as humans, but at a higher frequency than our ears can hear.

Plant sounds show how they feel

To carry out this study, the authors worked primarily with tobacco and tomato plants. However, they also used corn, cactus and meek nettle.

All these plants were divided into three groups. Some stem was cut offothers remained five days without watering and finally to the representatives of the third group he took good care of them. Later they entered columns, installed in turn in a basement isolated from background noise. In addition, 10 centimeters from each plant ultrasonic microphonecapable of picking up sounds with frequencies located 20 to 250 kHz. The human ear can only hear 16 kHzso that sounds we don’t hear can be detected.

When they studied the records, their suspicions began to come true. They were able to pick up sounds like cliques, which appear to be different for each species. In addition, they noticed that plants not subjected to any stress made less than one click per hour, while others, both damaged and dehydrated, made dozens of clicks per hour.

Algorithm for understanding language

The next step for these scientists was to paste the records into artificial intelligence algorithmso that he can understand what is happening to them. He trained on known data until he was finally able to tell for himself what kind of plant was making sounds and how stressed it was. He was even able to distinguish them in greenhouse with many other background noises.

On the other hand, it was observed that when dehydrated, the number of sounds gradually increased. until you reach the peak. From there they began to descend.

Scientists believe that, in a sense, this is a way for plants to communicate. We do not hear them, but some animals, such as bats, mice and some insects. In addition, sounds could be detected even by other plants.

It would be interesting if we could too. For this reason, the authors of the study are raising the possibility of using their artificial intelligence algorithm to farmers and gardeners they can hear to your plants. Thus, they can have a much more rough idea of ​​their needs. They would have told them how they are. Initially, this may have been of utility to those involved in large crops; But who knows, maybe in the future we can all listen to our plants. Those with a small hand in gardening will be grateful to hear your cries for help.
