The wandering of the heavens starts from the fake silly pillar

Chapter 258 Movement
The subject of physics is really broad and profound, just a sound wave involves a lot of knowledge,

In order to study this, Xiao Yao supplemented his knowledge of sound waves by following the system in space.

After I really studied sound waves with intelligent robots, I couldn't help being interested in this research. If I can really research it, this thing is quite useful.

When people have no precautions, they will feel uncomfortable or damage the hearing system in an environment with audible sounds above 120 decibels.

When the volume rises above 150 decibels, people in this environment will rupture and bleed their eardrums, lose their hearing, and even become mentally disturbed.

After research, it is found that infrasound waves are not easy to attenuate and are not easily absorbed by water and air. The wavelength of infrasound waves is often very long, so it can be diffracted around obstacles like electromagnetic waves. The killing range is large, but it is difficult to control the direction.

High-power infrasound waves can cause strong resonance in internal organs, causing nausea, headaches, difficulty in breathing, and even rupture of blood vessels and damage to internal organs.The effect of high-power ultrasonic waves is similar to that of infrasound waves, but its transmission direction is better than that of infrasound waves. It propagates almost along a straight line, is easy to control, has strong straight line penetration ability, but has a small killing range.

Generally, sonic weapons do not use sound waves in the audible frequency range of humans, because infrasound waves and ultrasonic waves are highly concealed.

Infrasonic weapons can be divided into two categories. One is neurological infrasonic weapons. The oscillation frequency is very similar to the rhythm of the human brain. When resonance occurs, it will strongly stimulate the human brain, causing people to be insane.

The other type is visceral infrasonic weapons, whose oscillation frequency is close to the natural oscillation frequency of the internal organs of the human body. When resonance occurs, it will cause severe pain to the internal organs of the human body, and even cause abnormalities in the human body until death.

Xiao Yao felt that it would be better to get a light infrasonic self-defense weapon first.

One week after Professor Xu organized the sonic experiment, Xiao Yao digested the knowledge he had learned, and then began to make light sonic weapons according to the manufacturing method of the sonic self-defense weapon.

The equipment in the research institute is complete, and while everyone was eating, Xiao Yao assembled the remaining parts by himself in the laboratory.

It took a week, after all the parts were made, and then assembled.

When the sonic weapon was in his hand, Xiao Yao said, "Can this weapon temporarily incapacitate people?"

"Don't you know if you experimented with the water cup next to you?" The system replied lazily

"It's a good idea. I'll try it out first."

Xiao Yao held the sonic weapon and pressed the switch on the water glass on the table, and suddenly there was a "bang", the water glass on the table flew upside down and fell to the ground, the glass shattered all over the floor.

"The system, doesn't it mean that it will only make people feel physically uncomfortable? If it's a human being, I'm afraid it won't work. It's such a short distance." Xiao Yao looked at the water glass on the ground in horror.
"You should worry about yourself first." A machine-like voice came from your mind

The sound of hurried footsteps sounded at the door of the laboratory, and the guards in military uniform quickly surrounded the laboratory. Seven or eight soldiers with live ammunition came in, looking at every corner of the laboratory vigilantly. from the laboratory.

Looking around, he saw Xiao Yao staring at them blankly, holding a strange-looking thing that didn't look like a gun in his hand.

The laboratory is a very important place, and any disturbance should be taken very seriously. This is their duty, and that is to protect the researchers.

There was a sound just now, and the guards outside responded quickly to ensure that the researchers were not harmed in the first place.

Xiao Yao subconsciously raised his hand and said, "I didn't do anything."

After all, I made the noise myself.
Professor Xu is still drinking tea in the lounge. This is why he likes to drink a cup of tea after meals every day to refresh himself. He hurried to the laboratory when he heard the sound
Seeing Xiao Yao raised his hand in a daze, he asked, "What's going on, Xiao Wang, Xiao Yao is my research assistant."

The soldier surnamed Wang replied: "I don't know, we didn't ask him to raise his hand, but we just heard the movement and came in to check."

"What's the matter with Xiao Yao, why are you raising your hand properly?" Professor Xu was puzzled
"I just did an experiment, and they came in when there was a noise." Xiao Yao replied honestly, he really did nothing wrong.

Professor Song naturally saw the weird weapon in Xiao Yao's hands, as well as the shattered glass on the ground.

"Are you under too much pressure?" Professor Xu suspected that Xiao Yao's experiment had failed, and took out the water glass to vent his anger.

Xiao Yao heard it, and immediately shook his head and said, "Professor, I really did an experiment just now."

Xiao Yao picked up the infrasonic weapon he researched: "If you don't believe me, I'll give you an experiment."

So he pressed the switch on another water cup next to him.

With a "bang", the water glass shattered and flew upside down the moment it touched the sound wave.

The moment the security guard heard the voice, he touched his waist, held the weapon tightly in his hand, and waited for the captain's order.

Captain Wang didn't make any moves. He had heard of Xiao Yao, the proud son of the scientific research community. Otherwise, he would have taken it just after he entered the laboratory. something.

"The laboratory is under martial law. No one in the laboratory is allowed to go out, nor is anyone allowed to come in, and no one is allowed to pass on information to the outside world." Captain Wang gave orders to the soldiers around him.

Professor Xu ran over quickly, then nervously picked up the sonic weapon in Xiao Yao's hand, his hands trembling with excitement, and in an instant he saw the way, this little guy made out the infrasonic weapon, turned his head to study After a long time, he didn't see any clips or anything like that, and then said: "Xiao Yao, is this really a sonic offensive weapon?"

"What was just emitted was sound waves." Xiao Yao replied
Professor Xu planned to test Xiao Yao's sonic weapon himself, but he pointed at the last water glass on the table and pressed the switch, and the water glass shattered like the first two and flew out backwards.

Professor Xu's eyes were wet instantly, and he gently stroked the infrasonic weapon,
"Professor, are you okay?" Xiao Yao asked
Hearing Xiao Yao's question, Professor Xu suddenly patted Xiao Yao's shoulder lightly and laughed loudly: "Hahaha, you really live up to your reputation as the proud son of heaven. Your head is indeed different from ordinary people."

Xiao Yao was at a loss. At this time, the researchers were blocked at the door of the laboratory by soldiers, and they couldn't get in without Captain Wang's order.

Soon a dozen soldiers came in, took the infrasonic weapon from Professor Xu, and hurriedly left the laboratory with the materials in Xiao Yao's hand.
