Chapter 902

Ethan recalled, "first of all, this thing can start and stop quickly. I was interrupted by it several times. Secondly, it can open a circular anechoic range, and it can expand and narrow this range in a slow way. If Li Yun is in control, I doubt it can freely control the anechoic range.

Finally, no matter how many kinds of sounds are mixed together, they can be eliminated together, and they can perfectly cancel our voices with the pitch of my singing

She talks with great admiration. She is a student admitted to Zhonghai city. She is not an actor who can only act.

Li Yun nodded and said with a smile: "in general, the function of this product is so simple, but it is so magical."

From the previous experience, it's easy to figure out what this muffler is, and eliminating sound is its only function.

"This thing..."

Lu Ming several people can't help but stand up and walk to the white cabinet, it seems to want to see what kind of principle it is and how it works.

The audience was a little surprised. Unexpectedly, even President Lu Ming didn't know about this product. Where did this muffler come from?

Li Yun said: "well, I'll show it again. You can feel the charm of this product freely."

With that, Li Yun asked people to play back the Song Yi Shanshan sang, which was recorded just now. At the same time, he started the anechoic hallucinograph with his mind, making it cover half the people under the stage.

After knowing the magic of this thing, the reporters at the bottom were excited and walked back and forth in the dividing line of noise elimination.

When you get into the silencing area, you can hear isan's singing. When you go out, you can't hear anything immediately.

There seems to be an invisible wall in the middle, and it is also a very strong sound insulation wall, which absorbs all the sound.

People are having fun going in and out at the dividing line. Even Yi Shanshan, Lu Ming and others can't help running down to experience how the muffler is.

"It's really black technology, my God! Will noise pollution be completely solved in the future

"If it can be as cheap as a few hundred yuan and the power consumption is small, I think it's something that every household must carry!"

"I don't know if every household has to memorize it, but in the city's construction site, every engineering team must have several. They are too disturbing to the people."

"There are also some families on the street. It's just an artifact!"

"It's a must for square dancing."

At the moment, many entertainment reporters are even reluctant to interview Yi Shanshan. They quickly tweet that super energy technology company has released a super powerful black technology, which has attracted netizens' comments on the Internet, saying that they are in the middle of eating melons and watching plays.

When they finally had enough, the Q & a session of the press conference officially began.

"May I ask chairman Li Yun, how much is the price of such a wide range of silencers?"

"It won't exceed 10000 yuan. This one has high power and can cover a kilometer. Basically, one can meet the needs of most big scenes."

"Excuse me, can small silencers only cover one room, or even a smaller area?"

"It can be done. The range of one meter is the smallest and the price is the cheapest. If it is smaller, it will be more expensive."

"Chairman Li Yun, I would like to ask you a question that you are most concerned about. Will this muffler have side effects. Such as nausea and vomiting after using it for a long time, or causing some other problems? "

"Basically not. This machine has been tested for a long time..."
