Godly Master’s System Plug-in
Chapter 903: Noise reduction, muffler
In fact, the gods have been using it for a long time. Judging from the principle of the muffler given by Xiao Ai, this thing actually uses sound to eliminate sound.
Under everyone's attention, Li Yun said: "About the principle of this machine, I think everyone has learned it in junior high school physics.
We know that the reason why people can hear sound is firstly because the vibration of the sound source causes the surrounding medium molecules to oscillate, forming sound waves. Sound waves propagate in the air in the form of longitudinal waves. It has the characteristics of waves, has interference phenomena, and obeys the principle of superposition of waves.
A series of sound waves are composed of two spaced apart ** and troughs. When encountering another wave, if ** and ** are superimposed, the trough and trough are superimposed, the amplitude will increase; if ** and the trough are superimposed, the amplitude will cancel each other out.
When applied to sound waves, this amplitude change due to interference is directly reflected in the size of the sound. In other words, if we can create "anti-sonic waves" that have the same waveform as the sound waves of the noise, and then superimpose them in a way that cancels each other out, then the noise can disappear. "
Everyone nodded to express their understanding, this is indeed the content of junior high school.
Li Yun continued: "The active noise-reduction headphones currently on the market use this kind of noise reduction method of'killing poison with poison.'
But there is a problem with noise-canceling headphones. I believe people who wear headphones for a long time know it. "
Everyone laughed consciously. Even the best ears will produce a sultry feeling after wearing them for a long time, making people's ears very uncomfortable, and even a feeling of vomiting.
"The difficulty of active noise reduction technology is that it requires very precise time control of sound waves. If the time difference is not calculated properly, it is likely that the noise is not suppressed, but strengthened, which is self-defeating. At the same time, the barriers of noise reduction algorithms are also very high. If you want to do active noise reduction, you must rely on your own acoustic knowledge to master modeling and simulation, and finally find the most suitable filter design and parameters based on earphone noise reduction through different attempts."
Li Yun continued to explain: "But this muffler is different. It has an intelligent system that can monitor the sound waves from the outside in real time, and can react quickly to generate appropriate anti-sound waves..."
Everyone was confused by Li Yun's explanation of the principles of Xuanke, and in the end only understood one thing. The principle of this thing is to emit anti-sound waves under the control of the intelligent system.
In other words, the only downside of the muffler is that after turning on this thing, the human body will actually be placed in the noise, but the noise cannot be heard by humans.
Hearing that it was just such a bad thing, people who were looking forward to this magical thing were relieved.
In fact, the human body is within the range of sound at all times. Car horns, human voices, firecrackers, etc., as long as they are not too loud, or people are too sensitive to these sounds, there will be no problems.
Lu Ming understood. When he thought of the strong artificial intelligence life form Xiao Ai he saw last night, he already understood that the intelligent system inside this muffler was probably made by Xiao Ai.
After answering everyone’s questions, Li Yun breathed a sigh of relief and said: “The first batch of mufflers will be available for interviews soon. If nothing else, they will be available for sale in three days. Friends from the press can follow the invitation letter of this press conference for free in the future. Receive a small muffler, and we will discuss specific matters later."
Everyone breathed a sigh of relief. This press conference ended smoothly, and everyone's hearts will be frightened if it doesn't end. This black technology can really shock people's ears.
"In addition, in one month, Taisheng Technology, a subsidiary of Yuyue Group, will release a new product."
Everyone was shocked, come back?
Li Yun smiled and said: "The name of the conference can be called: bright future, the beginning of a new era. Of course, it can also be called, blinding your eyes!"
