bats coming soon rock’n’roll hall of fame? According to a recent study carried out by scientists at the Université du Danemark du Sud, where the conclusions are published on Tuesday in the colonnades of the Plos Biology magazine, the chauves-souris are able to enlarge their vocal ranges in order to communicate between they.
Through this process, they are able to produce low-frequency grunts, thanks to structures in the larynx called ventricular folds, which are the same ones used by singers. death metal to produce bass sounds at extremely low frequencies.
It should be noted that this physical peculiarity is not present in all humans and that its use is not reserved for this musical style, as it is also found among specialists in Xöömej, an impressive traditional song originating in Mongolia and the Russian region of Tuva. , made only with the throat.
long distance communication
Science already knew that to hunt, bats emit ultrasonic noises in order to locate obstacles or animals in the dark.
It is also in the margin of work on these ultrasounds that the scientists came, by chance, with this discovery, by taking a video at accelerated speed of the bat vocal cords in action. There, the researchers noticed that these ventricular folds vibrated and produced lower frequencies.
“If you listen to a bat colony in the summer, you can hear these calls very clearly. We do not know the function of these calls, but they are given when they are annoyed by their peers, or when they fly or bond. a colony”, he found out, in the columns of the guardianProfessor Coen Elemans who participated in this research.
These deep sounds are extremely rare in the animal kingdom. According to the scientists, this peculiarity is probably due to the fact that the ultrasound that bats emit to hunt can only travel a few meters. These deeper grunts thus allow communication over a greater distance.
