Silicon Valley, Dwight Acoustics Room.

Girls' Generation is walking in the corridor of the real yàn room led by a middle-aged man in a white lab coat, this man has a black R-like thing on his eyes, and his mouth makes a "da-da-da" sound quite regularly when he walks.

Xu Xian found an opportunity and leaned into Phoebe's ear and whispered, "Phoebe, is he really unable to see anything?"

Phoebe glanced at her and diǎn diǎn head.

Xu Xian suddenly showed an incredible expression, and while following everyone, he paid close attention to the footsteps of the man leading the way.

After a while, everyone was taken to the door of a certain room, and the man listened and reached for the doorknob, but it was obvious to everyone that he did not grasp the doorknob accurately the first time, but paused slightly after reaching out, then moved sideways again, and then moved down again before grasping the doorknob.

The man said with a smile as he opened the door: "Just now the guide system is helping me indicate the specific location of the doorknob, and when I feel the road and obstacles myself, there is no way to do it for smaller things, but with the help of the guide system, I can live without the help of a guide cane in my usual life." ”

Phoebe helped everyone translate as she followed everyone into the door.

After everyone entered the room, they found that the decoration in the room was very special, the walls and sheds here were decorated with many special diǎn similar to crosshairs, and the materials of the walls were also a little strange. One wall is half like sand and the other half is somewhat like dirt, another half is like cement and the other half is wood, half of the third wall is like polished marble on the pavement, half is some like glass, half of the fourth wall looks like the most common street tiles, and half is like asphalt like road pavement. All the materials of the walls extend about a meter on the ground, and the various blocks of materials converge towards the center of the room, and about a meter from the center of the room, they are unified into pure metal.

The man who brought everyone over did not make a sound this time, but walked to the center of the room with even steps, then turned to everyone and said, "This is the place where the blind people are taught advanced recognition skills.@os_. Square. After learning echolocation skills, blind people can actually get out of the house and integrate into social life. However, this requires them to go to the place relatively speaking, less interference, or even no disturbance of the place, which is actually for many blind people, although it is a huge progress to change their lives, but in fact there are still restrictions on life, although there are many people who will take the initiative to help the blind after seeing the guide stick, but not everyone has such thoughts, especially for the blind, to go away from the original place of life, feel the scenery of different places, there are still considerable obstacles - Don't think it's weird, after learning echolocation, blind people can indeed 'see' the scenery. ”

Phoebe translated his words to the group again, and then the man added: "Actually, as early as 1918, some blind people living in mountainous areas or in the more remote countryside used echolocation recording, but this method is often not accurate, especially when someone finds it interesting to imitate the sound source made by the blind, this method can easily be disturbed. Don't think it's impossible, for example, a child or a bored person or a drunk person would do such a thing. Although there are still many universities and laboratories that are working on this skill, I think that with the support of Titan, the echolocation technology in our laboratory is the most suitable for blind people. ”

Phoebe doubled again, and when it came to someone making trouble, the sisters all had expressions of disapproval or disgust on their faces, while SNN glanced at Phoebe and secretly touched Phoebe's arm with her hand.

The man added: "As I said earlier, the blind man's sense of hearing is very keen, and this is the room at the beginning of the advanced skills training, so that the blind can judge the road surface by themselves according to the feeling on their feet, so as to ensure that the blind can walk on the safe road most of the time, and the reason why the wall is made of the same material as the road surface is to facilitate the blind people to practice the echo of the corresponding road surface under their feet." The diǎn on the wall is to allow the blind to find the correct practice position with the help of the guide system after entering the practice room. That's it, do you have any questions?"

After Phoebe finished translating, An asked, "Mr. Nathan, why do you still have to do such an exercise when the blind man has already learned the skill of echolocation and has the help of a guide?" ”

An asked in English, and Nathan replied: "Actually, it has something to do with the idea of some blind people, they think that although it is much more convenient to use the guide system, but this system can also make mistakes, if you are outside, once it goes wrong, it is likely to put the blind people who use the guide in danger, so we really started to study the feasibility of echolocation skills in more complex situations, and the road recognition skill is an attempt that we think can help the blind get rid of the guidance dependence." ”

After Nathan finished speaking, he said, "Well, in fact, this skill is quite difficult to master, especially

Nathan waited for Phoebe to finish translating, then asked, "Do you have any questions?"

Yun'er asked curiously at this time, "Mr. Nathan, if a normal person wants to master this skill, will it be more difficult than a blind person?"

After Yun'er's question was translated by Phoebe, Nathan diǎn diǎn diǎn head and said, "It's really harder, but relatively speaking, it's still easier to grasp than some people who are born unseen." After all, people who are born invisible can learn echolocation, but in the world they understand with the help of echolocation skills, it is still different from normal people and people who are blind. ”

After Phoebe translated again, she said to her sisters: "This time I came here to record the voices of my sisters, and the standard commentary sound in the guide system that was officially released to the public, and all future versions of the guide system will only use our voice." I am here today, one is to let my sisters feel that it is quite meaningful to experience this matter for themselves, and the other is to let my sisters know about the information related to the things we will promote at the Paralympic Games. ”

Everyone looked at each other, and Taeyeon asked curiously: "By the way, Phoebe, why doesn't our group show up on this? Other people's group shows that they all have a charity link, and this time we came to the United States, in addition to eating or playing, will there be something not good?"

After everyone heard Taeyeon's words, they all felt a little strange, after all, in South Korea, it is a very common thing to broadcast stars participating in charity projects on TV, it can be said that as long as it is a Korean star, they have participated in charity programs, even Girls' Generation is no exception, everyone does not feel that they are doing a show, after all, the whole circle is participating, if you don't do it, it will seem a little strange, and the Korean people are also willing to see the stars on TV because they are tired of being dogs, such as the famous wild variety show of TV B, which broadcasts at least one episode of charity content every quarter on average, which is also one of the trump cards that make the ratings of this show prosperous.

SNN preempted Phoebe and said: " That,I think it's still as good as it is now.,There's no need to add such a plot in the group comprehensive.,To be honest.,Although Phoebe said that she sponsored the entire real Yàn project.,And even provided that guide system.,But I think,Phoebe doesn't play a major role in this matter.,The real hero is a person like Dr. Nathan.,Although the vision is normal.,But the vision is closed by guò technology.,Like the blind people, they only use their sense of hearing to help with research.,Phoebe should think the same way.。 ”

Phoebe smiled and said, "Sister Sun is right. ”

"Cut, as long as it was your sister Sun, you never said it was wrong. Taeyeon suddenly gave SNN and Phoebe blank looks.

Suyoung reached out and put her hand on Taeyeon's shoulder, looked down at Taeyeon and said, "I also think what SNN said makes sense, alas, what should I do?"

Taeyeon glanced at Su-young again and said, "I also listened to it when I was down there, Dr. Nathan did this to provide a research sample for the psychological adjustment plan for those who could have seen but became blind due to a sudden accident." I deliberately asked this because I didn't know you were concentrating when you were downstairs. ”

"Cut ......" Xiuying saw that there were outsiders there, and thought it would be better to save some face for Taeyeon, but in fact, she really forgot, on the way here, Barbara said that the entire Dwight Acoustic Real Yàn Room was acquired by Phoebe.

Seeing that Xiuying was speechless, Taeyeon suddenly said to SNN again: "You guy too, help her deal with me if it's okay, don't look at her now in line with your statement, as long as I'm not there, she won't bully you like that when I'm not there." ”

SNN suddenly nodded his head and reached out to bring Taeyeon from under so-young's arm to his side, and the two little ones snorted at so-young together as if they had discussed it.

The others laughed at the activity of the three of them, but everyone quickly stopped laughing, in fact, since visiting the echolocation research area for the blind in the real yàn room, everyone has not laughed much.

This time, it was Xu Xian who was the first to stop the sisters from laughing: "Sisters, the doctors are still watching us." ”

Yu Li whispered: "The ...... he can't see"

Jessica also whispered, "He can hear ......"

Hyoyeon was puzzled by these two people, and said, "He doesn't seem to know Korean, right?

"Hey, hey......" Everyone chuckled a few more times.

During this time, Phoebe did not translate the conversation to Dr. Nathan, but Dr. Nathan looked at everyone with a smile on the corner of his mouth, and even grinned a few times when everyone laughed, because everyone was too focused just now, he didn't notice that he was laughing along.

Dr. Nathan heard the laughter fade away before he said, "Alright, girls, it's time to laugh." I heard that you are going to Beijing as a volunteer for the Paralympic Games, and I hope to help us introduce more products to the blind and deaf-mute when the time comes. ”

After Phoebe translated for everyone again, Jessica asked curiously, "Isn't this real yàn room dedicated to the study of sound, how can there be something designed for the deaf and mute?"

"Of course, this real yàn room is basically doing acoustics, so there are also ultrasound projects, and one of the products is developed for the deaf and dumb," Nathan said. ”

Next, everyone continued to visit many places under the leadership of Nathan, and also learned some beauty things through some research results in the Guò Shi Yàn room, such as the new external fat burning technology, running shoes, etc., the most important thing is to understand one thing, that is, it is a shame not to know, as long as a little effort and time, it will make people's understanding of the world change dramatically, even the blind and deaf-mute are actively trying to get the tools to understand the world, as a normal person, often say that I don't know, it's really a bit too embarrassing……
