On the hospital bed, Lin Hong was still lying on the bed. pen%fun%ge www.biquge.info{http:

He unexpectedly discovered that he could explore his surroundings through the echoes of sounds, and he couldn't help but feel very fresh and magical.

In fact, the phenomenon of echolocation is very common in nature, such as bats, toothed whales, seals and sea lions have such a magical ability, they can detect the environment through their own ultrasonic waves, especially bats, it can fly rapidly in the air without touching any obstacles, and even through this ability, catch small mosquitoes in the air, its echolocation skills have undoubtedly reached the point of superb.

Although it is known that such a phenomenon exists in nature, and scientists have also carried out targeted research to develop artificial equipment such as submarine sonar, this is really a bit too far away for Lin Hong. It's like hearing that the country has successfully launched a satellite again. I don't have any intersection with myself at all, and I don't feel anything.

But this time was different, and he experienced the effects of echolocation firsthand.

The unintentional "click" sound from his mouth actually modeled the surrounding environment in his brain at once, which is really a bit magical at first glance.

Lin Hong forgot to continue writing drivers for the time being, and instead began to carefully study the principle of this phenomenon.

He is such a character, this exploration of unknown territory has an inexplicable attraction to him, if he does not figure out his essential principle, his heart is as if there are countless ants biting, it is simply crazy.

As a result, a "click" sounded in the ward from time to time, and Xu Wenjing and Wang Yuqing were completely numb to it.

After some exploration, Lin Hong finally had a deeper understanding of the basic principles of echolocation.

Echo is the reflection of sound waves after they collide with an object, and is most noticeable in narrow areas or where there is an obstruction in front of it.

When Lin Hong was a child, he also played the echo game, ran to the top of the mountain, and then roared loudly below. After a while, there will be an echo coming back.

These echoes come back at different times and at different levels. Even, if you listen closely, the tonal nature of the sound is not the same.

After testing, Lin Hong gradually figured out the rules.

Among them, the timing of the sound coming back is very related to the distance of the object from oneself, which is actually a conversion process, if quantified. {http:

The speed of sound and the time of propagation are multiplied by two, and the distance of the object is obtained.

Of course, the propagation time is generally very short, especially in this kind of room, with the wonderful speed of 340 meters of sound, it can run back and forth ten times in less than a second.

Precisely because of the short time. The sound is so small that the echo is often ignored, mainly overlapping with the original sound. The interval between the two is too short to distinguish at all. That's why, in a cramped, enclosed room, the voice feels louder than in an open environment.

Lin Hong uses the superbrain system to monitor sounds, and the sensitivity of receiving sound signals has been improved like never before. Of course, it's not that the native system isn't sensitive, it may be because of evolutionary needs, the human ear directly filters out these invalid noises and blurs them.

The most typical example is the blind, who have no vision. Hearing will be enhanced accordingly, and being able to hear sounds that ordinary people can't hear is equivalent to the brain reopening the fuzzy filtering mechanism.

Based on the subtle differences in the echo, the superbrain system can calculate the distance of the object reflecting the echo, and can also change its wavelength. Determine the size of the object. Finally, there is the nature of the object, which can be identified by the amplitude of the sound, and there are obvious differences in the sound waves reflected back by objects of different materials.

The vista, size, shape, and material are all taken together to make it possible to detect the surrounding environment clearly.

As soon as Lin Hong heard these echoes, he directly realized this, which is why he became interested in this phenomenon.

In order to display them more vividly on the retina screen, Lin Hong directly processed these signals, directly modeled these signals graphically, and then displayed them on the retina screen, so that they were as close as possible to seeing directly with the eyes.

Of course, the images created in this way have no color characteristics, all of them are black, white and gray, which is a bit like the dim light at night, and the scenery seen by the eye only has a faint outline, and there is no color or other information at all.

In the future, if necessary, Lin Hong can also add an automatic dyeing function, first determine what kind of object it is, and then dye it according to the common object color, so that the scenery seen will not be too monotonous and depressing.

In addition, Lin Hong also added a direction judgment mechanism to it, which can adjust the angle of the picture on the retina screen through the control of neck steering and other body parts.

For example, when the head is turned to the left, the image on the retina screen also rotates, and the scene on the left is directly displayed in front of it, which is a complete simulation of normal vision.

When Lin Hong did this function well, the time was already at night, and at this time, Wang Yuqing had already gone home, leaving Xu Wenjing alone to still be by Lin Hong's side and take care of him.

Lin Hong then programmed a simple function for his right hand, which was just able to control the index finger to move up and down, similar to mouse clicking, so that Xu Wenjing only needed to hold his right hand, and the two could communicate, instead of doing it in the blink of an eye and writing a note as before. Moreover, now that Lin Hong's hearing has basically returned to normal, Xu Wenjing can speak to him directly through language.

There were only the two of them left, and Lin Hong was distracted, while continuing to write the driver of the limb control module, he explained the basic situation of his brain to Xu Wenjing.

Xu Wenjing only then knew that Lin Hong had fallen when he was a child, and it happened to hit the back of his head, and since then, he has begun to be different. In the beginning, he was mentally retarded, became a fool, looked down upon, and was ridiculed. And it was from that time that he suffered from "insomnia" and never needed to sleep.

When Xu Wenjing heard this, her heart was pinched, she really didn't expect that Lin Hong had such a sad experience in her childhood, and tears involuntarily rolled in her eyes.

Fortunately, Lin Hong's brain became better and better, and he began to try his best to obtain knowledge, and finally met Xu Zhizhong, stepped into the palace of radio, and broke into the world of ham, which also became a springboard in turn and met many people, including Xu Wenjing.

"What about your insomnia, did you get better?" After Xu Wenjing's mood calmed down, he remembered that Lin Hong couldn't sleep when he was a child.

She couldn't imagine what it would be like to be alone if she didn't sleep.

I think that at the beginning, when she was celebrating the New Year, she wanted to follow her brother's example many times, and insisted on not sleeping all night, but in the end, she never succeeded once. The state of wanting to sleep but not being able to sleep was so uncomfortable, and she had several such hard and unforgettable experiences.

Lin Hong's fingers tapped rhythmically on her palm:

No, this problem has always existed. At the beginning, I also went to the hospital for a check-up, but I couldn't find out what the cause was. Later, for fear of my father's concern, I hid the incident, and they still don't know about it. When they get here, don't tell them for now.

Hearing his words, Xu Wenjing was completely shocked.

"You're saying you've never slept since you were a child?"

This news is too shocking!

This is more than ten years, Xu Wenjing touched Lin Hong's face in distress, and muttered:

"Why haven't you ever heard about it?"

Actually, there is no problem, and not being able to sleep has no effect. As you know, I later contacted Wushu to relax the brain by standing on the pile. It is precisely because of this that the headache that used to be the problem gradually disappeared. It only took me 20 years, but it was equivalent to living for nearly 40 years, and I still earned it.

"Your joke isn't funny at all!" Xu Wenjing said distressedly, "Is it because of this reason that you became like this this time?" Hong, this matter cannot be ignored, you must be effectively treated. Shall we go to see the best brain doctor in the world? They must know how to treat your disease. ”

It's useless, and the current medicine has not yet reached this level. I'm very aware of my problem, and rest assured, I'm sure I'll find a way. Aren't you looking at my recovery now? Believe me, you should be able to walk tomorrow. The good news for you is that I did fall asleep yesterday, and that's good news, isn't it?

When Xu Wenjing heard this, she thought for a long time and said, "Hong, is there anything else you haven't told me?" How did you find a way to do it yourself? How do you know when you'll be able to get better? ”

In fact, Xu Wenjing had doubts about this question for a long time. Now, it's clear that he's recovering in a good direction, but it seems so incomprehensible, he's a patient himself, why does he seem to know everything about these things?

Lin Hong was silent for a while, and finally his fingers began to move again:

Would you believe me if I said that the human brain can be programmed like a computer? (To be continued.) )
