Concept in Definition ABC

Through the term infrasound it designates that sound wave characterized by having a frequency lower than that which is capable of perceive the human ear, being approximately 20 Hz.

Infrasound is an advantage enjoyed by many animals, especially the larger ones, such is the case of the elephants, what use it to communicate over long distances. The ability to hear at great distances is plausible thanks to the significant size of their heads and the separation that their ears present, this being directly proportional to the frequency that they are capable of capture. It should be noted that elephants even manage to capture infrasound by perceiving the vibrations that they produce themselves with the movements of their legs, because their nails act as conductive sensors of the sounds that present low frequency.

On your side, the Tigers, also use the infrasound of their roars at the time of the hunting for the paralyzing effect it has. And likewise, Whales are other animals that make use of infrasound at the time of communication.

A curiosity in relation to infrasound is that our body is also capable of producing this type of sound through the movement of the muscles, sliding over each other, through the ears and even the heart.

Meanwhile, the app infrasound par excellence is given at the behest of the detection of objects; as a consequence of the scarce absorption of this type of wave in the middle, that is, an infrasound will be absorbed four times less than an ultrasound. Now, the objects to be located must be large enough since in the aforementioned frequencies the length of the wave is really great, a situation that will end up limiting the diameter of the object in question.
