Resonance and way, how to use it.

Resonance and way, how to use it.

After Nikola Tesla made his famous acoustic test, what almost destroyed his laboratory, acoustic systems have planned to use in many things in war and peace. If we would use modern material we can create the artificial version of the system, which whale uses to create the sound for its sonar system, and that would make it possible to create things like hearing aids, which would need no electricity.

The hearing aid, what would not need electricity might seem a very rare thing, but by using modern nanotube technology would be possible to create a small system, which would put in the ear canal. That thing would base in the same kind of structure, what is found in the skull of whales. The acoustic system would have many canals through it, and those extremely small tubes would resonate with each other.

That would be possible to create the acoustic system, which will increase the volume without active systems, and if we would use small diameter carbon tubes this kind of system or structure could be quite a small size. When we are thinking passive hearing aids, what are basing the acoustic resonance, we are mean systems, which work an opposite side than some musical instruments.

When the instrument like acoustic guitar makes sound it bases that the air would resonate in the chamber, and then it would increase the power of the wave movement. But what if in the chamber of guitar would be the Melon, the copy of the sound organ of whales? Those small tubes would increase the sound at a very high level, and that kind of experiment can injure people and destroy the material. Those things can also use as an attachment for microphones, which can hear very low noise.

In the 1960's CIA:s laboratories created an idea that the agents would have mouth organs, where would be the artificial melon inside it. That system was hard to make in the past, but using modern carbon fibers those needed tubes would be easy to make, and that system can give an extremely strong voice. The idea was that the agent could escape by using that system. And there have been many other things, where resonance would seem being an interesting tool.

Also, the CIA planned to slip the agents inside the soviet command bunkers, and they would leave the whistles with balloons inside those buildings. Those whistles would equip with the material, what causes resonance in the bunker, what would make the structure weaker. But the use of resonance is also research for destroying chemical weapons and other chemicals. In that case, the system would use sound or electromagnetic radiation for cutting the molecules of gas. Also, there are tested sound systems, which are planned to break the cores of the ammunition and rifles.

Then we are thinking resonance as the way, what would make it possible to remove concrete from the walls, the thing, that is needed is the bite of the same concrete which is used in the wall. Another way to use resonance simply put the steel inside the concrete structure resonate, which would cause the damages in concrete. This kind of thing has been created for demolition sites because that thing would decrease the need to use explosives. They can also be used to make the cores of bunkers weaker, which can increase the power of own ammunition.

The thing, what wave movements really mean

The thing, what wave movements really mean

1. Acoustics is a really important thing. 

A Finnish architect Alvar Aalto was the master of the acoustics and acoustics is actually another way to say wave movements, and the thing is that the wave movements can be really dangerous. If the sound starts to resonate the other material, that would cause damage in the hardest materials in the world. So that means that if we would use the concrete to make the oscillation layer to the loudspeaker, that would cause resonance to all materials, what is around it.

This resonance has almost caused the death of Nikola Tesla because that inventor accidentally caused the effect, where resonance moved to the structures of his laboratory house, and that house almost collapsed because the resonance broke the concrete. In fact, there have been made tests about the sonars, or sound weapons, which would cause resonance to the concrete or steel surfaces.

2. Resonance can break even the hardest materials

Those systems mission is to break the bunkers or bodies of ships and aircraft. If there is a loudspeaker, what causes resonance to the weapons, that cause cracks in the materials, what those things have been made.

And the thing is that the sound is a thing, what can travel faster than sound. I know, that this feels insane, but the air molecules act like bullets, and if the diaphragm of the loudspeaker would move faster than sound, that will cause the effect, where those air molecules are going to move faster than sound.

The movement of the layer pushes the molecule ahead with the same speed as itself moves. If we would put the loudspeaker to the aircraft, what moves about 1000 km/h, that means that the sound molecules would go ahead with the speed of sound plus 1000 km/h.

3. If the air molecules travel faster than sound, would that cause the "sonic boom"

When the layer of the loudspeaker would move faster than sound, that thing will cause the "sonic boom", what can be really devastating. That would be a really devastating thing.  The effect of the fast-moving loudspeaker is the same with supersonic aircraft, and that makes a really hard pressure wave.

And in fact, the loudspeaker can make the sound wave, what is harder than the steel. But in that case, the diaphragm must move very high speed. If the layer moves the speed of Mach 2, the air molecules would move ahead with speed of Mach 2.

But when we are thinking about things like mysterious sound "hum", what might sometimes cause death. A reason for that is that there is a possibility, that this sound causes resonance in the axons, and this thing would break the connections in the human brains.

4. The layer can turn the wavelength to another

And when we talking about the form, and if that form contains the wave layer, what will target to the wrong position, that thing will make the concert really horrible experience. In fact, if there is the situation, that in some tube would drop the bite of the bone, that thing could cause the resonance to the skull or the bones of the person, and that thing can cause really bad injuries.

If the layer is made by using the waveform, what has the same length, with the sound, what causes pain, that thing will make that experience really "interesting". This makes that kind of things dangerous, and this is the reason, why the acoustics is important.
