Officer Yang looked at the autopsy report for a while, scratched his hair, and said in confusion:

"This is a shock to death?"

"Well, judging from the autopsy, that's what it is. His eardrum was ruptured, and his internal organs were horrible. Officer Wang said with an eyebrow twist.

"But, shocked to death? Isn't this incredible? ”

※

The cause of the deceased's death was not only unbelievable to the police, but also very surprising by Zishumo and others.

"Master, what does it mean to be shocked to death? Could it be that this Ke Yihan was tied to some machine by someone, and DuangDuangDuang was shocked to death? Or will the murderer have some magical internal skills, beating cattle across the mountains and shattering other people's internal organs with one palm? Jia Yangren jumped up excitedly and said with gestures.

Ding Weiqiu smiled: "Senior, don't you see, you're still a martial arts fan?" ”

"That's it! The kung fu of the five-star country is broad and profound! Enveloped! Wow! Don't say it's me, my grandfather likes it too! Jia Yangren said and immediately did two somersaults to express his love for kung fu.

Mao Youxian shook the handkerchief in front of him, and said faintly: "Ouch, senior, don't play monkey show, you can't solve the problem with this effort, we still don't know how he was shocked to death." Brother Mo, you must know, right? ”

Zi Shumo sat on the sofa, touched his neck with one hand, and put the other hand on Tu Xiuwen's shoulder:

"Theoretically, this question should be like this, that is, he is in a place close to the frequency of his visceral vibration, which causes resonance. There are also many types of resonance, and in general, they are caused by energy shocks. Since the report said that the deceased's eardrum was ruptured, I think it is very likely that his death was caused by the impact of sound waves. ”

When Jia Yangren heard this, he became even more energetic, and suddenly jumped in front of Zi Shumo and said:

"Master, isn't it like a lion's roar? Or is it like one of those who play the piano and kill people!? ”

Everyone looked at Jia Yangren and smiled: "That's a movie, you still take it seriously!" ”

Zi Shumo stood up with a smile, walked aside to get a glass of water, bypassed Jia Yangren, and said with a smile:

"No, the foreigners are not wrong, theoretically, a loud enough sound or a special frequency can cause human death. Isn't it, Wenwen? ”

Tu Xiuwen was holding a cup of tea in a daze, when she suddenly heard Zi Shumo ask her, and quickly came back to her senses:

"Huh? Do you say sound? What I know is that there was a volcanic eruption that reached 310 decibels, and even sailors 64 kilometers away were shocked to their eardrums. ”

Hearing this, Ding Weiqiu also stretched his neck and leaned over and said, "Oh! I've heard something similar, I have a cousin who was in the army and was a gunner. He told me that that kind of large-caliber howitzer, when fired, can reach 180 decibels! Standing next to without earbuds is really going to die! There have been records of people who were shocked to death and stunned. But now, you have to wear earplugs. ”

When Mao Youxian heard this, he exaggeratedly covered his ears with his hands: "Wow! It's so scary, even the sound can make people die, the earth is too dangerous! ”

Zi Shumo smiled: "What are you panicking about? Do you think 180 decibels is so easy to make? What's going on? The sound of our daily speech is only 50 to 60 decibels, and the noise emitted by electric drills is 110 decibels, and the sound of jet engines can reach 140 decibels. Therefore, the sounds of everyday life will not cause you to have health problems. ”

The same cannot be said for the fact that there are two parameters that are critical to sound waves, one is the decibel of intensity, and the other is the hertz of frequency. The sounds that our human ears can hear are between 20 and 20,000 hertz, above or below this range, we can't hear them, but they are still there. Tu Xiuwen tilted her head and looked at Zi Shumo.

Zi Shumo smiled and nodded: "That's right, that's right, this supplement is very important." Spending a lot of time in a low-frequency infrasonic environment can be problematic. For example, the resonance frequency of the human eye is 19 Hz, and when a human stays in an environment of 19 Hz, the vision will be blurred.

Or between 0.5 and 8 Hz, when the decibel reaches 117, it will affect our lungs, become breathing disorders, bones tremble, cause damage to joints in a short time, and cause nausea and even blindness for a long time. ”

Zhang Huiyuan, who had not spoken for a long time, suddenly straightened up at this time and said: "By the way, wasn't there any silent mosquito repellent in the early years, and later someone used it and said that they were dizzy or something, is this the reason?" ”

Zi Shumo nodded, and Angela on the side also straightened up:

"You say so, Ke Yihan was killed by a voice? However, as you said, either infrasound or long-term will have to be effective. Either the sound is more than 180 decibels, and the noise is so loud that so many people present didn't hear it? ”

"Well, sound travels through a medium, air, metal, wood, water, etc., it can penetrate the human body, so it can also cause damage to the human body. However, in this transmission process, it disperses and decays rapidly, so it is not fatal in everyday life, and the key to fatality lies in two words...... Closed. In a confined environment, 240 decibels can blow a person's head open, but only if it is in a confined environment. After Zi Shumo finished speaking, he paced back to Tu Xiuwen's side, grabbed Tu Xiuwen's shoulder with one hand and laughed quietly:

"Am I right?"

Tu Xiuwen couldn't smile bitterly, feeling that the eyes of everyone around her were staring at her, she blushed uncomfortably and lowered her head, and hummed in a voice the size of a mosquito.

Then, Tu Xiuwen raised her head, looked at Angela and said, "Since it is said that a confined space is needed to use the sound of the limit that human beings can bear to kill, then, where is there such a confined space in the competition venue?" ”

Angela shook her head: "I only know that it is an old building, and I don't know anything else." ”

"It's easy, just look up what that place was used for?" Ding Weiqiu immediately took out his mobile phone and began to search.

The rest of the group formed up in groups, nervously thinking about how to keep themselves safe from being killed by the sound waves. Although it was all unfounded nonsense, the more those guys talked, the more excited they became, and the more they talked, the more energetic they became, as if they would die immediately if they didn't wear headphones when they went out.

Tu Xiuwen silently shrank under Zi Shumo's arm, still holding the water cup in a daze, the water in the water cup was already cold.

Zi Shumo reached out and took away the water cup in her hand, and said with a smile: "Do you want to use your palm to heat cold water?" ”

Tu Xiuwen came back to her senses, hurriedly broke away from Zi Shumo, snatched the cup from his hand, and ran straight to the kitchen.

Zishu was puzzled, got up and chased her to the kitchen: "What's wrong with you?" I've been so reluctant since yesterday. "Take a hundred plating and read the latest chapter of "Amnesia Secret Detective Claw Book House" for free for the first time.
