Acoustic Levitation – A Phenomena Which Make You Feel Gravityless.
Acoustic levitation is a process by which we can hold a particle in the air by using acoustic radiation pressure of intense sound waves in the medium. It defy the laws of the gravity.
So above you have read the definition of Acoustic Levitation. Now you will learn what acoustic levitation is and all the details about acoustic navigation so let’s get started.
Why it seems like magic?
Now if you see the effects of Acoustic levitation in general it will seems to you like a magic because with the help of Acoustic Levitation we can hold anything in the air without any support which is amazingly very good and magical to see.
The particle will feel like floating in the air which is not less than the magic. Because we all know that it is impossible to hold on any thing in the air due to the gravity of earth. But this acoustic levitation overcomes the gravity and make particles fly in the air.
Science Behind this Magic !
Acoustic Levitation basically use the sound wave properties to make solids, liquids and heavy gases to float. This phenomena of Acoustic levitation can be done in both normal or reduced Gravity. Or we can say that we can levitate objects in air or any gas with the help of sound waves. And the sound that is used in acoustic levitation is normally above 150 decibel. Whereas the normal conversation that we do is approx 50 dB and the night club is about 110 dB so it is beyond and the human hearing limit. That’s why in the acoustic levitation when the sound waves do their work, produced by the transducer we cannot hear anything we just see its impact.
An Acoustic Levitator contains 2 things first is the transducer and second one is the reflector. Transducer produces the wave at ultrasonic frequencies and reflector reflects it back and when this process goes on. There created a wave in which there are some nodes which are not moving from the place. And when we place any object or particle at these nodes, along with these notes this particles or object also don’t move and hover in the air without any support. The pleasure of waves that is used to hold things in the air is known as acoustic radiation pressure.
Modern day’s acoustic levitator can now hold up to some kilos weight and mostly used in industries. And also there is one Industry that makes acoustic levitator make it available for the public and anyone can order it online and assemble it at the home and make a handy levitator.
Can Create Anti Gravity Field
Acoustic Levitation creates an anti gravity filed which can make anything hold in the air which is very good and is amazing to see. And the sound that is used by the acoustic levitator is as loud as a jet but we rarely hear it because it is of Ultrasonic range which is out of human hearing limit. And if we make use of simple sound for the acoustic levitation it will be too much loud and hence will create problem so we use sound more than 150 dB.
