The research results are out, but it is not so easy to turn the research results into experimental products.

The most troublesome problem is that the sound waves of hedging are not completely canceled out, and in the hedging environment, everyone will feel some abnormalities to some extent, like something stuffed in their ears, which is indescribably awkward.

Some people are more sensitive, and even have obvious side effects such as dizziness and nausea.

The side effects of the hedging of the two infrasonic waves are more serious, and all the experimental zoos have shown varying degrees of restlessness in the hedging experiments conducted by animals, and various physical injuries will occur after staying in the hedging environment for a long time.

In order to completely solve this problem, the Northern Capital set up a research group led by the military to conduct a series of experiments simulating battlefield conditions.

The experiment was conducted in a fully enclosed acoustic laboratory with a high-intensity infrasonic sound source, and several monkeys wearing power armor were used to test the hedging device.

These monkeys were originally used for experiments, but because they have been kept in the laboratory, they have not been affected by the insect plague.

There are a number of such zoos in laboratories around the world, and many believe that these actions should no longer be used for experimentation, but should be saved for the post-war period to restore wildlife populations.

But the military doesn't care whether the monkeys are endangered or not, and the bigwigs only care about the results of the experiment, so the laboratory does not hesitate to pull them into the experimental field.

Professionals sent by the military put on the monkey's armor, and after testing the armor's performance, the monkey was sent to the experimental area.

There are two types of power armor worn by the monkeys, one is the standard armor with nothing added to it, and the other is the experimental armor with the addition of sonic hedging equipment.

The power of this hedging device installed on the armor is relatively low, and it can only cancel out the external sound waves with a radius of about one meter, and after the equipment is turned on, a hedging safety zone with a radius of one meter can be formed near the armor, so as to solve the damage of infrasound waves to personnel.

At the beginning of the experiment, the moment the infrasonic cannon was turned on, the hedging device on the monkey's body was quickly activated, and the corresponding sound waves were used to cancel out the external sound waves.

But a new problem immediately appeared, although the intensity of the infrasonic wave emitted by the hedging equipment was relatively small, it was also an infrasound wave, which not only canceled out the external sound wave, but also penetrated into the armor, and it only took a few seconds for the monkey in the armor to be shocked to death by the infrasonic wave emitted by the recoil equipment, and there was no survivor.

The experiment was forced to end, and when the infrasonic source was turned off, the personnel entered the experimental area and found that the monkeys were well protected by the armor without hedging equipment, although the monkeys who were lucky enough to survive were also harmed by the infrasound, but at least they were not shocked to death by the infrasonic on the spot.

The flaw is very obvious, but it is not impossible to solve, since the sound waves are transmitted into the armor, then find a way to isolate it.

The designers immediately made corresponding modifications, removed the hedging equipment originally embedded in the armor, put several layers of soundproofing material between the armor and the hedging equipment, and restarted the experiment.

This time the results were much better, the monkeys in the armor were irritable, but none of them died from the experiment.

After increasing the thickness of the barrier, the results did not change, and the experimenter immediately realized that it was not the problem of the barrier and locked down the cause in the shortest possible time.

The problem is very simple, although the hedging device cancels out the external sound waves, the infrasonic penetration emitted by itself is not small at all, even if it is separated from the armor by a thick isolation material, the infrasound waves can still penetrate the armor.

After penetrating the armor, the infrasonic wave intensity decreases significantly, and it is not fatal but can cause injury.

The experimenter could only reduce the output intensity of the hedging device, and the offset range of the hedging device was rapidly reduced, from one meter to seventy centimeters, and from seventy centimeters to fifty centimeters, until this time, the intensity of the sound wave penetrating the armor fell to a safe range.

The discomfort is definitely there, but you should be able to endure it.

The experiment was initially successful, but what can 50 centimeters protect?

There is very little room for further improvement of the equipment, but fortunately, the designers quickly found a solution to the problem - since one hedging device can't solve the problem, then bring a few more hedging equipment in front of you, up and down, left and right!

After intense modification, a new sonic hedging armor was born, which was equipped with a total of nine hedging devices on the limbs and torso to fully protect the personnel in the armor.

The following experiments proved that this set of armor can effectively protect the safety of personnel in high-intensity infrasonic waves, which basically meets the requirements of the military.

It's just that the volume of the hedging equipment is a bit large, and there are so many hedging equipment on one armor, it looks particularly bloated and rough, and the personnel sent by the military to help after seeing the armor invariably shook their heads, saying that this kind of armor has no actual combat value.

The volume of the hedging equipment has reached its limit, and reducing the volume will affect the hedging effect, and the experiment has come to a standstill again.

Every time the experiment was carried out, everyone thought that it was about to be successful, but the results of each experiment were unsatisfactory, and many designers felt that no matter how they improved the design, it would be impossible to meet the requirements of Beidu.

For a while, the experiment seemed to have reached a dead end, and no matter how much it was saved, it could not find a direction for success.

Some people do give up on themselves, but more designers still refuse to give up and try to solve the problem.

Soon, someone came up with a new solution - since the current way of thinking can't solve the problem, why not think about it the other way around?

At first glance, everyone was a little confused, not knowing what the words meant, but the engineer immediately came up with dry goods: since the power armor can't fit so many hedging equipment, why not install the hedging equipment on other carriers?

Like an armored car or a tank!

Everyone woke up from a dream and immediately realized the correctness of this line of thinking.

The hedging equipment had been successful, and the experimental team immediately reported the plan and brought in several armored vehicles as quickly as possible.

The experimental team carried out a comprehensive modification of the armored car, and all the armor in all directions were equipped with soundproof interlayers, with which the crew of the armored car put on power armor, even if the hedging equipment was running at full power.

The improved armored vehicle was an unprecedented success in the experiments, and all the experimental animals were unharmed.

The results of the experiment were reported to the high-level, and when they saw the final report, the high-level also couldn't laugh or cry, they planned to study a new type of infrasonic weapon, but they didn't expect the final research result to be an anti-infrasonic armored vehicle!

However, in any case, the protection problem of infrasound waves has finally been solved, and it barely meets the requirements of the northern capital...... That's what we are talking about!
