Chapter 386 Details Determine Success or Failure! Is There Noise in the Laboratory?

Boom!

Gao Lian banged the gavel, waved his hand to Lin Mo and said: "Defendant's defender..."

Before Gao Lian finished speaking, Lin Mo interrupted directly and said: "Okay, I won't ramble anymore, let's get to the point now."

As he spoke, Lin Mo exuded a fierce aura.

The atmosphere in the entire court became serious.

"Previously, the prosecutor said that the night at the Jiangnan University Research Center was very quiet, and there would be no other sounds to interfere with Chengbo's hearing.

Well, I seriously suspect that the prosecutor did not carefully study the information collected by the police. "

With that said, Lin Mo accurately pulled out an A4 paper from the nearly 30cm thick document.

Su Yang hurriedly retorted: "Are you kidding me! I've read the file countless times!"

Lin Mo glanced at him, then held the information in his hand and said:

"Presiding judge, this is what the police recorded about the situation in Professor Xu Han's laboratory on the night of the incident. Four of the machines were turned on and made a beeping sound when in standby. The steel cutting machine showed signs of being used. The experiment There are some small pieces of steel scattered on the floor of the room...

To put it simply, the laboratory equipment was run that night.

This is a photo taken by the police. "

Photos taken by the police in the laboratory in the early morning of that night were shown on the big screen. Many machines had their lights flashing and were in standby mode. The ground was messy and there were many debris.

Su Yang's eyelids were twitching wildly, and he said very speechlessly: "The equipment in the laboratory has nothing to do with the case. It's impossible for me to memorize all the details."

Lin Mo waved his hand and ignored his explanation, but continued:

"Among them, we can see universal testing machines, metallographic cutting machines/grinding and polishing machines, etc., as well as ventilation equipment, etc..."

Lin Mo finished introducing the equipment that had been operated in the laboratory, and then submitted a bunch of recordings to the presiding judge.

"Presiding judge, this is the sound of a universal testing machine. This instrument is mainly used to test the mechanical properties of steel and conduct mechanical tests such as tensile impact and impact on steel."

After speaking, Lin Mo motioned to the staff to play the sound of the instrument.

"Buzz——"

"This is the sound when the instrument is moving, and the approximate decibel is around 60dB."

"Woo-bang-"

"This is a bending test of steel by an instrument. The final crackling sound of the steel breaking, the decibels during bending were around 70dB, and the decibels at the moment of bursting reached close to 90dm."

Then Lin Mo submitted the sound of the cutting machine.

“This is a metallographic cutting machine, the sound decibel is small, around 60db.

This is a grinding wheel cutting machine. The sound is very loud. It is also our most common cutting machine. The sound is usually above 100dB! "

"Zizzizi——"

The harsh sound of a grinding machine cutting can be heard in the video.

Then, Lin Mo explained the decibels of several devices.

Su Yang frowned at this moment: "Lin Mo, what are you doing? This is not a mechanical engineering laboratory. What's the use of explaining the decibel size of these instruments?!"

Lin Mo just chuckled, smiled and said nothing, and continued to introduce the remaining instruments.

Observation room.

Because of Yu Bing's words just now, the judges were so angry that they didn't dare to speak out.

Yu Bing said at this time: "Now do you understand why I just said that you won't read the dossier?"

The judges looked at each other in confusion. Now Lin Mo was introducing the equipment in the laboratory. Does this... have much to do with the case?

The corner of Yu Bing's lips curled up: "I know what you are thinking. The relationship is not only big, but also very big! Lin Mo has already introduced the decibel size of the machine. Combined with the previous waves of auditory processing disorder, don't you still think about it? come out?"

Such a reminder is equivalent to putting food in the mouths of all the judges.

Everyone suddenly realized.

"The details of all cases exist in the files." Yu Bing sighed. If Lin Mo hadn't brought it up, Yu Bing felt that he wouldn't have been able to discover such details.

At the same time, Lin Mo had already introduced all the instruments during the court hearing.

Gao Lian also asked: "Defendant's defender, are the instruments you introduced related to this case?"

Lin Mo: "Presiding judge, don't worry, watch this surveillance video first."

This video is also evidence submitted by the police and does not require Lin Mo to apply for certification.

As soon as the picture came out, it was Xu Han's laboratory surveillance perspective. There were two figures in the picture.

It is obvious that one of them is Xie Bo, and the other is Xu Han.

In the picture, Xu Han was standing in the center of the laboratory, pointing his hands and saying something intensely.

Xie Bo, on the other hand, was running around the entire laboratory, operating all the machines almost at the same time!

The instruments for cutting steel were not enough, so he even used a grinding wheel cutting machine to cut a piece of steel. Sparks were flying at the scene!

"Presiding judge, what I mean by releasing this scene is that at 9:41 that night, Xie Bo, under the instruction of Xu Han, simultaneously controlled all the instruments in the laboratory for cutting steel and verifying the strength of the steel.

Combined with the decibels I listed before when the instrument is started, you can believe how noisy the sound environment in the laboratory is now!

In the picture, in order to save experimental time, Xie Bo skillfully and perfectly controlled five machines at the same time. There was no idle time, and the sound from the five machines occupied the entire laboratory. "

Gao Lian nodded, he understood what Lin Mo meant.

Lin Mo said so much, just to show that after 9:41 pm, the laboratory was already in a noisy state due to multiple machines running at the same time.

"Then, Mr. Judge, let's see when Dr. Cheng Bo returned to the laboratory."

Then Lin Mo gestured to play the surveillance video.

It was the picture of the hall of the experimental center. It was 9:40 pm when Cheng Bo walked into the building.

"Mr. Judge, I calculated that it would take Cheng Bo at least two minutes to get to the laboratory. So when he arrived, the laboratory was filled with noise!"

After saying that, Lin Mo glanced at Su Yang.

Su Yang's face turned pale instantly. He now understood what Lin Mo was arguing about!

Then Lin Mo looked at Cheng Bo again and said:

"Dr. Cheng Bo, when you rushed to the laboratory, you probably only saw Xu Han excitedly saying something to Xie Bo. As for what you heard, I think your ears are not good enough to handle it in such a noisy environment. You may have just heard Xu Han scolding Xie Bo a few times.

Then, based on the stereotype that Xu Han usually exploits you and scolds you, you think Xu Han is scolding Xie Bo and forcing Xie Bo to work.
