It turned out that the rectangular box contained earplugs, but they were not ordinary earplugs.
After Yong Ming made it clear that the thing he just took out was the earplugs Huang Hanhan mentioned, he specifically explained the reason why he had such earplugs in his hand.
“When I imported military equipment from Germany, I considered some emergencies that I would face in the future, so I introduced such professional military earplugs.
Now, that's when these earplugs come in handy."
After hearing Yong Ming's introduction, Xie Liuyun and the other four people were itchy, especially Shang Baifeng, who couldn't wait.
Compared to Shang Baifeng's enthusiasm, Xie Liuyun and Sheng Qingfeng were a little calmer, but they were still eager to try on the earplugs and experience what it felt like.
The one who is calmer than them is Huang Hanhan. After all, she is a girl, so she should be more reserved.
In fact, she also wanted to wear these German military earplugs to see how powerful they were.
Yong Ming looked at Xie Liuyun and others and guessed what they were thinking, so he said: "Please be patient for a moment and don't think about wearing these earplugs.
Why don't you calm down and listen to me tell you why you should wear such earplugs in the next actions."
When he said this, Yong Ming suddenly stopped and said: "I suddenly thought, why don't any of you come and tell me first, why do you wear such earplugs in action?"
In the view of Xie Liuyun and others, this question is too simple.
Xie Liuyun turned to look at Sheng Qingfeng, and Sheng Qingfeng then looked at Shang Baifeng.
Shang Baifeng felt a little embarrassed when Sheng Qingfeng looked at him, so he turned to look at Huang Hanhan.
Finally, without much discussion, Xie Liuyun, Sheng Qingfeng and Shang Baifeng all looked at Huang Hanhan in unison.
Their meaning is very obvious, that is, this question raised by Yong Ming, why not let Huang Hanhan answer it.
Huang Hanhan looked at Xie Liuyun, Sheng Qingfeng, Shang Baifeng and others and knew what they wanted him to do.
It's no wonder that after seeing Yong Ming take out the rectangular box, she was the first person to react and know what was in the box.
As for the question raised by Yong Ming about why he should use earplugs in the next action, it is naturally better for Huang Hanhan to answer it.
Xie Liuyun's question was answered by Huang Hanhan, and now Yong Ming's question is answered by Huang Hanhan. It is a perfect closed-loop question and answer session.
Xie Liuyun is the chief officer of the "Four Davids of the Yong Family" and the leader of Sheng Qingfeng and others.
Yong Ming is the chief envoy of "Yong Wang Wei" and the core of all of them.
Huang Hanhan is the last supervisor of the "Four Davids of the Yong Family" and the only female member of this team formed by Yong Ming.
The questions raised by Xie Liuyun and Yong Ming were all answered by Huang Hanhan. This feeling was really good in Sheng Qingfeng's opinion.
It is a good thing for Huang Hanhan to give Huang Hanhan more opportunities to show his talents and wisdom.
Sheng Qingfeng loves Huang Hanhan very much, and naturally hopes that Huang Hanhan can gain more recognition and recognition in front of everyone.
Now, seeing that Huang Hanhan has such a good opportunity to show himself, can you not be happy for Huang Hanhan?
In fact, when Sheng Qingfeng took a quick look at the contents of the box that Yong Ming took out, he knew they were earplugs.
This is a seemingly small but miraculous medical device that he often uses in the process of diagnosing and treating mental illnesses.
After wearing such earplugs, it can help patients and patients who are irritable or depressed and have such psychological problems to calm down quickly and gain a rare peace of mind.
Therefore, he is very familiar with earplugs and has done some research on them.
It's just that he uses medical-grade earplugs, which are mainly used to cut off all external sounds so that the patient and the patient can be in a state of inner peace.
There is a big difference between the earplugs he used before and the professional earplugs used by the German Wehrmacht that Yong Ming took out this time.
Therefore, Sheng Qingfeng is very interested in such military professional level earplugs.
What interests him is that such earplugs can actually reduce the sound that is so loud that it can be called thunder, so that it can be heard within the range of normal listening.
This is not something that can be done easily.
It is not difficult to isolate sound through technology.
However, it is difficult to reduce the external sound entering the ear canal and keep the noise under control.
At the very least, it is difficult to do at this stage.
This requires rigorous design and development ideas in the initial design stage of earplugs.
Later, when entering the production stage of earplugs, professional processing and exquisite production technology are required to fully comply with the design requirements and produce finished products that meet military standards.
At this stage, domestic machinery, equipment and production processes are unable to achieve this.
This is also something that Sheng Qingfeng is worried about in terms of the production process and quality of some domestic medical devices after many years of diagnosis and treatment of mental illness.
He had never had the opportunity to come into contact with some military equipment and related equipment imported from abroad, like what he was using now around Yong Ming.
In the process of actually using these equipment, Sheng Qingfeng was very inspired after he learned about their performance.
Inspired by this, Sheng Qingfeng decided to focus on research on some relatively small mechanical equipment in the future.
He feels that this can effectively improve their efficiency in performing tasks in the future, and at the same time, it can also better meet their own needs in operational tasks.
He likes to study these machines, which may be related to his hobby of playing with objects since he was a child.
It is good to import things from abroad, but after all, maintenance and warranty are quite troublesome in actual use or after damage occurs.
We can't let these things that seem unimportant, but are actually very important, always rely on imports and be controlled by others, right?
Sheng Qingfeng's idea was very good. He felt that he had the responsibility and obligation to do this well.
For this reason, he wanted to choose a suitable time to specifically communicate with Yong Ming about the relevant situation.
As long as he can obtain Yong Ming's support, Sheng Qingfeng is confident that in a short period of time, he will be able to combine the technical parameters of some existing mechanical equipment, make use of existing technical conditions, and produce high-performance products based on actual operational needs.
