Forget Cloaks, Invisible Acoustic Bottles Can Bend Sound Waves To Hide Objects
We all are quite familiar with the sound waves and thus know very well that these waves do not tend to ‘hold much power’. However, scientists came across certain experiments that revealed to them the capacity of the sound waves to get objects hidden from view and even ‘levitate them in the air’ on directing these waves in the right way. In United States, the researchers came forward with a development in technology that is based on the manipulation of the sound waves through certain specified directed paths that tend to remain fixed ‘around an acoustic bottle’.
This newly developed techniques can help in the re-routing procedure of these sound waves at the vicinity of the particular acoustic object. Thus, in this process, the objects get invisible to the ‘sonar radiation’. Even sound waves can be made to ‘lift and manipulate objects’ that include certain ‘microorganisms, particles and even drops of water’. These activities are made possible when the acoustic bottle aids in carrying out the levitation.
This acoustic bottle is not only a theoretical concept but also has been practically designed by the research workers of the ‘Lawrence Berkeley National Laboratory’ based in California. This acoustic bottle is basically designed as a ‘three-dimensional structure’ that is made up of certain waves that are of high pressure and are acoustic in nature.
These bottles can cause effective deviations in the oath of the sound waves due to their inherent acoustic nature and thus can bend their paths in open air towards the planned or desired direction. Although the sound waves travel in straight lines, being quite similar to the light waves, yet these waves can be bend into different angles due to phenomena like diffraction, reflection or even refraction.
The acoustic bottles are made in such a way that the centre of the shell has got zero pressure while the peripheral regions have the maximum acoustic pressure. Thus, the sound waves that form the bottle are found in concentrated beams that travel through the high pressure zones of the acoustic shell. There remains no sound waves at the centre as the high pressure at the walls tend to exert a pulling force on the sound waves, and thus can trap sound ideally.https://www.aartiinformatics.com/technology/sound-waves-to-get-objects-hidden-from-view/https://www.aartiinformatics.com/wp-content/uploads/2014/08/acoustic-bottle.jpghttps://www.aartiinformatics.com/wp-content/uploads/2014/08/acoustic-bottle-300x300.jpgTECHNOLOGYacoustic bottle,development,development in technology,experiment,sonar radiation,sound wavesWe all are quite familiar with the sound waves and thus know very well that these waves do not tend to ‘hold much power’.
