A living creature needs food to survive. After all, we human beings live, struggle and earn so much to fill our stomachs. Agriculture, which pours healthy lives to people, is in the problem, as we are all familiar with headlines like ―crop fields destroyed by wild animals!‖ and so on. A fence is a structure that encloses an area, typically outdoors, and is usually constructed from posts that are connected by boards, wire, rails or netting. A fence differs from a wall in not having a solid foundation along with its whole length. Alternatives to fencing include a ditch (sometimes filled with water, forming a moat). Though there are many kinds of fences practiced, still we are not able to control the intruding of animals into the crop fields. Bringing a solution to this is our project. The application of infrasound in an agricultural field can bring a vast change. There is a two-way advantage, as the crop field is made safe by restricting the entry of animals, similarly, the animals are safe, they need not be harmed, thereby giving equal importance to lives of animals, humans, and crops too. Several surveys conducted on natural disasters shows that the death rate of animals is much lower than that of the humans. Natural disasters like earthquake, hurricane, tornado, volcanic eruption led to the production of vibration at infrasonic level. It’s been a myth for years that how animals could predict and escape from the disasters, now science behind it is revealed that animals can hear and sense the infrasound. The capability of hearing and sensing the infrasound makes the animals vacate from the place of the disaster occurring. Still, several methods are used to shoo away the animals from their restricted places. But while following these methods, there are harms caused to animals as well as to humans in some way or the other. To rectify this problem we believe infrasound can be a solution. By generating infrasound, we make animals get frightened about stepping towards the place from where the sound is originating. By using Acoustic fence we can avoid the disadvantages of paling, chemical, and electrical fences, and saving the lives of humans and animals.
