First of all, infrasound is a sound wave, and as such, it has many limitations.
Infrasound is inefficient at transferring energy to objects, and maintaining a narrow beam over long distances is impractical, as its energy density would continuously decrease.
Secondly, infrasound weapons will not be cheap to manufacture.
For example, a lot of money was spent to build an infrasound weapon, which uses the principle of resonance to kill a person or a group of people in a building.
It takes a long time of bombardment to have any effect; it would be more effective to just fire a single artillery shell.
Finally, infrasound has very poor controllability.
Infrasound has a very low frequency, below 20 Hz, but a very long wavelength, allowing it to travel much farther than ordinary sound waves, light waves, and radio waves.
For example, infrasound waves with frequencies below 1 Hz can travel thousands or even tens of thousands of kilometers away. Infrasound waves have extremely strong penetrating power, capable of penetrating not only the atmosphere, seawater, and soil, but also solid reinforced concrete buildings, and even tanks, warships, submarines, and airplanes.
This is why many countries dare not develop such weapons.
You've released the infrasound, and the target is dead, but the remaining wavebands continue to transmit, making them impossible to track or eliminate.
Who knows what kind of aftereffects these transmitted infrasound waves might have?
However, these problems can actually be solved here.
He's a man with a full-force aura.
Sound waves require a medium to transmit, and infrasound is no exception.
The transmission of sound waves in the air also relies on various floating particles or other substances in the air, not to mention in solids and liquids.
He can completely control the uncontrollability of infrasound by controlling the vibration of molecules.
The range of his full-force field has now expanded to about 10 kilometers, meaning he can control everything within that 10-kilometer radius.
If you aim the infrasound at the target and destroy it, you can immediately activate a full-force field to quell all the abnormally active molecules that have become agitated by the infrasound. Wouldn't that solve the problem?
Moreover, he can create a special channel for infrasound, a channel that is only for infrasound.
Infrasound can only propagate within this channel; media molecules elsewhere will remain silent under the influence of the full force field.
But here's the problem: this infrasound weapon is still limited to his personal use and cannot be mass-produced.
"Never mind, let's build one first. If it doesn't work, we can just keep it at home and not use it."
If it were the high price he had paid in the past, he might have refused to make this weapon.
However, the old man seems to have a deep obsession with the military industry.
Whether it was to please his grandfather or for some other purpose, he felt he had to make this guy.
In Gao Feng's heart, the old man was like his heaven and earth. After all, from the time he could remember, the first person he saw when he opened his eyes was his maternal grandfather.
Since Gao Feng has decided to develop infrasound weapons, he needs to make preparations.
The first thing to do is to determine the shape of the weapon: is it handheld or stationary?
If it's to be handheld, it will definitely be a single-soldier weapon, which will have much less lethality and can at most be used as a targeted elimination weapon.
If it's a base-mounted type, then that's formidable; it would at least be capable of annihilation.
After thinking for a while, Gao Ang decided to start with the handheld type.
Eat your food one bite at a time, walk your path one step at a time. Taking too big a step can easily lead to trouble...
He had only thought about the principles of infrasound weapons in his mind; it was still theoretical and had not yet been practically verified.
He caught another mouse and carefully recorded the vibration frequency of its organs.
For example, the heart, the brain, the stomach, and so on.
Since they are weapons, they must have different uses.
For some enemies, it's necessary to annihilate them; in that case, simply shatter their hearts.
Some methods simply aim to incapacitate the target, such as causing stomach aches or difficulty breathing.
Gao Ang opened his mouth, and a very deep voice came from his mouth.
The target of this sound wave was the little mouse running around in the yard.
He had created a temporary "sound channel" between himself and the rat, and no one else outside this channel would be affected by the infrasound.
The little mouse immediately became strange. At first, it was agitated, but after five seconds, it started rolling on the ground and even vomiting.
Ang stopped making noises, but the little mouse was still struggling. After half a minute, it recovered and continued to wander around unsteadily.
This time, he targeted the rat's stomach, which may have caused a resonance in the rat's stomach, causing it to vomit up what it had eaten.
After observing the area, everything was fine, there were no other abnormalities, and no infrasound escaping particles were detected.
"Perfect, let's get started."
Infrasound is, after all, a sound wave. To emit a sound wave of a certain frequency, two conditions need to be met.
One requirement is that there must be a sound source, which means there must be some kind of material that can vibrate;
Another aspect is the power source; an external force is needed to make the sound source vibrate in order to emit sound waves.
The sound source was easy to obtain; Gao Ang directly used a full-field printing technique to create another vocal cord that was exactly the same as his own.
As for the power source, it's even simpler: a small hair dryer will do. It sounds cheap, but it's very practical.
The difficulty in manufacturing infrasound weapons lies not in the power source, but in the material of the sound source.
Vibrations below 20 Hz, and stable vibrations over a long period of time, are a requirement that many materials cannot meet.
Even if a very rare material can emit sound waves at such a frequency, it is only temporary. Subsequently, it will resonate with the frequency it emits, thus failing.
Therefore, the material of this handheld weapon must also be a special material.
What material can compare to your own body cells?
Gao Ang drew inspiration from the cellular structure of his respiratory tract and oral cavity to print out a curved gun barrel.
The length and width of the curved barrel, even the grooves inside, were exactly the same as his own respiratory tract.
This gun barrel isn't just for aesthetics; it has a crowding and restraining effect.
One characteristic of infrasound is its extreme divergence and penetrating power, so there are currently no suitable materials to contain it, which is another reason why infrasound weapons cannot be mass-produced.
With this gun barrel printed according to its own material, infrasound can only be transmitted inside the gun barrel, and will not spread, be absorbed, or interfere with each other.
After installing the sound source material, that is, the printed vocal cord, in the same position as one's own vocal cord, the front end of this infrasound weapon is considered complete.
Next up is the powertrain.
Gao Ang originally planned to use a regular hair dryer, but after his experiments, he discovered that regular hair dryers have many problems.
On the one hand, there is a lack of power; to put it bluntly, his vocal cords cannot be moved!
If you can't blow your vocal cords, they can't vibrate, and without vibration, where do the sound waves come from?
On the other hand, he felt that using a regular hair dryer seemed a bit low-class and unworthy of the identity of an infrasound weapon.
"Then I'll get you a custom-made hair dryer!"
From blades to coils to specially designed batteries, everything is meticulously crafted atom by atom, recombine from one atom to another.
The coil itself is made of superconducting material, and the rotation speed and the resulting airflow are enough to move the vocal cords.
However, another problem arises: each object has a different vibration frequency, which means that the hair dryer needs to emit airflow of different intensities.
Therefore, he also needs to add a small component to control the rotation speed of the hair dryer motor.
Even with all that, Gao Feng found it still wasn't enough.
He needs to label the weapon with something easy to understand, like a turntable.
The dial has 2001 markings, representing 0-20.00 Hz.
When the pointer points to 10.11, it means that the weapon can emit infrasound waves at 10.11 Hz.
However, with the addition of these few small parts, the weapon's appearance has changed, even becoming somewhat strange.
Below is a thick, bulging thing, with a section of pipe in the middle that doesn't look straight and even has some strange curves.
Above is a device resembling a flattened balloon, where Gao Long simulates the part of himself from his throat to his mouth by printing.
Since this is the first infrasound weapon, it would be best for him to try to recreate the process of him emitting infrasound.
If this test is successful, he can continue to optimize the weapon.
For example, by using some synthetic materials, mass production can be achieved.
It took a lot of effort to make this weapon.
Once the weapon was completely finished, he couldn't think of any other flaws besides its appearance, and then it got dark again.
"Now, the moment of witnessing a miracle is about to begin!"
Another mouse, huddled in the corner, trembling with fear.
"The vibration frequency of a mouse's brain cells is 14.54 Hz. Once adjusted, aim at the mouse and turn on the power."
A very weak vibration came from my hand; the small motor had started working.
Immediately afterward, Gao Ang felt a wave of energy shooting out rapidly from the muzzle of the gun through his full-force field, the target of which was the rat on the ground.
The mouse, which had been sneaking around, suddenly snapped to attention and ran away.
Even after hitting a wall, it doesn't turn back and keeps crashing, as if it has lost its way.
As they approached, the mouse began to squeak loudly, a sound so loud it was almost unbearable to hear.
The cries grew weaker and weaker, and the impact of the crashing into the wall became smaller and smaller.
Seven seconds later, the mouse stopped moving completely, lying on its back with its belly exposed, dead.
Glancing at the gun barrel and then at the dead rat on the ground, Gao Ang slowly exhaled, "I guess that's settled."
During this process, he also discovered something interesting.
The infrasound did not spread as expected after it was emitted from the gun muzzle.
The muzzle diameter is 3.73 cm, and the distance between it and the mouse is 5.3 m.
When the infrasound reached the mouse, the diameter of the beam was only 3.74 cm.
In other words, even when hitting a target more than 1,000 meters away, the diameter of the beam is only 5.73 cm.
Even after a 10-kilometer accident, the body was only about 23.73 cm long, roughly the size of a person's head.
"This completely defies the common sense of physics!"
Something must have happened during this process that caused this infrasound wave to mutate?
From vibration frequency to amplitude, or rather from other unknown sources, there have been inexplicable and exponential changes.
Another beam of infrasound was emitted, and Gao Feng carefully observed every step from the vocal cords to the exit.
Finally, he discovered the secret.
