First of all, infrasound waves are sound waves, and since they are sound waves, they have many limitations.

Infrasound is inefficient at transferring energy to objects, and it is unrealistic to keep a narrow beam over long distances, and the energy density will keep decreasing.

Secondly, the cost of infrasonic weapons will not be too cheap.

For example, it costs a lot of money to build an infrasonic weapon that uses the principle of resonance to kill a person or group of people in a building.

It took a long time to bombard people before it had an effect, and it was better to come directly with a cannonball.

Finally, infrasound is too poorly controlled.

The frequency of infrasound sound waves is very low, below 20Hz, but the wavelength is very long, and the propagation distance is also very long, it is farther than ordinary sound waves, light waves and radio waves.

For example, infrasound waves with a frequency of less than 1 Hz can travel thousands to tens of thousands of kilometers away. Infrasound is extremely penetrating, penetrating not only the atmosphere, seawater, and soil, but also through sturdy reinforced concrete buildings, even tanks, warships, submarines, and airplanes.

It is for this reason that many countries do not dare to develop such weapons.

The infrasound waves are released, and the target is dead, but the remaining bands continue to transmit, and they can't even be tracked or destroyed.

Who knows what kind of after-effects these transmitted infrasound waves have?

But these problems can actually be solved here at high cost.

He's a man with all his might.

The transmission of sound waves requires a medium, and the same goes for infrasound waves.

The transmission of sound waves in the air also depends on various floats and sinks or other substances in the air, not to mention solids and liquids.

It is entirely possible to restrain the uncontrollability of infrasonic waves by controlling the vibrations of molecules.

The range of the full field has now expanded to about 10 kilometers, which means that he can control everything within this 10 kilometers.

The infrasonic waves are aimed at the target, and after destroying it, immediately launch an all-out field to quell all the abnormal activists who are agitated because of the infrasonic waves, isn't it okay?

Moreover, he can also open a special channel for infrasound, which is only for infrasound.

Infrasound waves can only be transmitted within this channel, and the medium molecules elsewhere will remain silent under the action of the full field.

But the problem is that such an infrasonic weapon is still limited to him alone, and it still can't be mass-produced.

"No matter, let's build one first, it's a big deal to put it at home and not use it. ”

If it had been the previous high, he would probably have refused to do such a weapon.

But the old man seems to have a deep obsession with the military industry.

Whether it was to please Grandpa or for some other purpose, he felt that he had to make this guy.

In his high heart, the old man can be said to be his god, after all, since he can remember, the first person he opened his eyes and saw was his grandfather.

Since he was going to make an infrasonic weapon, Gao Gao had to make preparations.

The first thing is to determine the shape of the weapon, whether it is hand-held or pedestal.

If you want to be hand-held, it will definitely be a single weapon, which will be much less lethal, at most as a targeted killing weapon.

If it's a pedestal, it's powerful, at least it has to be at the annihilation level.

After thinking about it for a while, Gao Gao decided to start with the handheld one.

The rice should be eaten one bite at a time, and the road should be walked step by step, and the steps are too big, and it is easy to pull the eggs......

The principle of infrasonic weapons, he has only gone through it in his head, can only be regarded as a theory, and has not yet been verified in practice.

He caught another rat and carefully recorded the vibrational frequency of its organs.

For example, the heart, such as the brain, such as the stomach, and so on.

Since it is a weapon, it must have a different purpose.

Some of them need to annihilate the enemy, so just break their hearts;

Some people need to be incapacitated, so they can have a stomachache or difficulty breathing.

Gao opened his mouth, and a very low voice came out of his mouth.

The target of this sound wave is the little mouse running around the yard.

He had made a temporary "sound channel" between him and the mouse, and no one outside of this channel would be affected by the infrasound wave.

The little mouse immediately became awkward, and at first became irritable, and after five seconds, began to roll on the ground, and even began to vomit things out of his mouth.

Gao Gao stopped speaking, and the little mouse was still struggling, and after half a minute, he slowed down and continued to wander around.

This time, he targeted the stomach of the mouse, which may have caused the resonance of the mouse's stomach and spit out what it had eaten.

After observing it for a while, everything was fine, there were no other anomalies, and there was no awareness of the wave particles that the infrasonic waves had escaped.

"Perfect, start. ”

After all, infrasound waves are a kind of sound waves, and two conditions need to be met to emit sound waves of a certain frequency;

One is to have a sound source, that is, to have a certain substance that can vibrate;

The other is power, which requires an external force to vibrate this sound source in order to emit sound waves.

The sound source is very good, and Gao Gao directly printed out another vocal cord that is the same as his own vocal cord with all his strength.

In terms of power, it is simpler, a small hair dryer will do, it sounds very low, but it is very practical.

The reason why infrasonic weapons are difficult to manufacture is not because of the power, but because of the material of the sound source.

Vibrations below 20 Hz, and stable for long periods of time, many materials do not meet this requirement.

Even if a few materials can emit sound waves of this frequency, they are temporary, and then they will resonate with the frequency they emit, resulting in hiccups.

Therefore, the material of this hand-held weapon must also be a special material.

What better material than your own body cells?

Gao Gao referred to the cell composition of his respiratory tract, mouth and other places, and printed a curved barrel.

The length and width of the curved barrel, and even the furrow inside, were exactly the same as his own airways.

This barrel is not for the sake of good looks, but has the effect of agglomeration restraint.

One of the characteristics of infrasonic is that it is extremely divergent, coupled with its extremely penetrating power, so there is no suitable material to restrain it, which is another reason why infrasonic weapons cannot be mass-produced.

With this barrel printed from his own material, infrasound waves can only be transmitted in the barrel, not spreading, not absorbing, and not affecting each other.

After installing the sound source material, that is, the printed vocal cord, in the same position as your own vocal cord, the front end of this infrasonic weapon is completed.

Then there's the power part.

Gao Gao originally planned to use an ordinary hair dryer, but after his experiments, he found that there were many problems with ordinary hair dryers.

On the one hand, there is a lack of motivation, to put it bluntly, he can't blow his vocal cords!

If you can't blow the vocal cords, the vocal cords can't vibrate, and if you don't vibrate, where are the sound waves?

On the other hand, he felt that using an ordinary hair dryer seemed to be a bit low, and he was not worthy of the identity of an infrasonic weapon.

"Then let's get you a special hair dryer!"

From the blades to the coils, to the special batteries, it is all expensive to reassemble an atom and an atom.

The material of the coil itself is superconducting, and the speed generated and the wind force brought by it are enough to blow the sound cords.

But again, the problem is that the vibration frequency of each object is different, that is, the hair dryer needs to emit different intensity of airflow.

So, he also had to add a widget that controls the rotation rate of the hair dryer motor.

With all this, it is not enough to find it high.

He had to mark the weapon with something easy to understand, like a turntable.

There are a total of 2001 scales on the turntable, representing 0-20.00 Hz.

When the pointer points to 10.11, it means that the weapon can emit an infrasound wave of 10.11 Hz.

It's just that with the addition of these few widgets, the appearance of this weapon has changed a bit, and even become a little strange.

Down there's a thick, bulging bunch, and in the middle is a section of pipe, which doesn't look straight either, and even has some odd curvatures.

Above, there is a device that resembles a flattened balloon, which is printed in a high-spirited way from the throat to the mouth.

After all, it was the first infrasonic weapon, and it was better for him to try to restore the process of emitting infrasonic waves himself.

If this experiment is successful, he can continue to optimize the weapon.

For example, use some synthetic materials, so that it can be mass-produced.

It took a lot of effort to make this weapon.

When the weapon was fully finished, he couldn't think of any other flaws, and it was dark again except for its appearance.

"Then it's time to witness the miracle!"

Another mouse, shivering in the corner.

"The rat's brain cells vibrate at a frequency of 14.54 hertz, and after adjustment, aim at the rat and start the power. ”

A very weak vibration came from the hand, and it was the small motor that was starting to work.

Immediately afterward, Gao Gao passed through the full field, and felt a wave of fluctuations along the muzzle of the gun, shooting out rapidly, and the target was the mouse on the ground.

The rat, which was still sneaking around, was instantly agitated and ran away.

Even if you hit the wall, you still don't look back, and continue to hit it, as if you have lost your way.

As it approached, the rat began to squeak and squeak, and the sound was a little unbearable to listen to.

The screams are getting weaker and weaker, and the amplitude of hitting the wall is getting smaller and smaller.

After 7 seconds, the rat stopped moving completely, and was dead on all fours, with its belly exposed.

glanced at the muzzle of the gun, and then at the dead rat on the ground, Gao Gao slowly exhaled, "It's done." ”

In the process, he also found an interesting thing.

After the infrasound wave was launched from the muzzle, it did not spread in all directions as expected.

THE MUZZLE DIAMETER IS 3.73CM, AND THE DISTANCE BETWEEN THE MUZZLE AND THE MOUSE IS 5.3M.

WHEN THIS INFRASOUND WAVE REACHED THE MOUSE, THE DIAMETER OF THE BEAM WAS ONLY 3.74CM.

IN OTHER WORDS, EVEN IF IT HITS A TARGET A KILOMETER AWAY, THE DIAMETER OF THE BEAM IS ONLY 5.73CM.

Ten kilometers of accidents, it is only about 23.73CM, about the same size as a person's head.

"This Nima completely violates the common sense of physics!"

What must have happened in this process to mutate this infrasound?

From the frequency of the vibration to the amplitude, or from other unknown places, there is a high and incomprehensible change.

Once again, an infrasonic wave was fired, carefully observing every process from the soundband to the exit.

Finally, he discovers the secret.
