Chapter 4 The second part of the magic sound phenomenon

"How could that be!" After hearing what Ryan said, Billy almost jumped out of bed.He even forgot that the IV needle was still stuck in his arm. "How can the wide-pharynx move in groups!" As a reporter for Natural Paradise, Billy certainly knew this knowledge, and he especially knew it all. "I've never heard of any deep-sea fish that pack like sardines." "Oh, don't be so excited, lie down first." Gordon pushed Billy down on the bed. "Then...a precursor to an earthquake?" Billy said looking around.There was no answer, but agreement was written on everyone's faces.

Earthquakes can be heralded by a variety of things, from mysterious glowing phenomena to catfish dropping.It is well known that deep-sea fish appear on the surface of the sea as omens.However, a large number of deep-sea fish appeared in groups, even Ryan and the others who made a living as marine biology, and even Billy, who had the title of reporter of a biological magazine, heard such things. Ryan decided to contact the weather station on San Eleanor Island.If it is a precursor to an earthquake, then the weather station's seismograph may show it.Unfortunately, the person in charge of the weather station was out, and only one staff member with no professional knowledge was on duty.

After two hours of IV drip, Billy made a full recovery.Perhaps the wide-swallowed fish incident became a sobering shot.But the doctor told him to sleep until evening.In the end, Hanluku stayed to take care of him, and the others went back to the research institute first. In the evening, Gordon called the hospital.Hajiri apologized again and again.When he hung up the phone, Billy asked him what was wrong, and Hanuri said it was about the "belt". "Video tape. I wanted to watch it here, so I got it out of the boat." Hajiri pointed to the corner of the room.Bags and pocket cameras with videotapes left there.

"Gordon got angry and said that everyone wanted to see this tape, so they rushed back, but I... It's terrible." "Haha, that's what happened." Haluku suddenly seemed to think of something, and turned around happily. "In that case, why don't we watch it?" Billy, of course, had no objection. Gordon put down the phone and returned to the studio anxiously. "That idiot, deliberately unloaded the strap from the boat." After listening to his words, Ryan and Jack became dejected. "It can't be helped. Let's just take down the tape, too."

As Jack spoke, he took out the multi-channel tape, put it in the seat recorder, and started to adjust.All the audio recorded in the sea must be copied to the hard disk, and then various analyzes are performed on the computer.Ryan and the others had nothing to do until all the tapes recorded in the past four hours were copied.Since there were no videotapes, they could only listen to the sounds of the sea and dolphins while sipping coffee. After a long, restless coffee break, the three of them leaned out involuntarily as the duplication was about to end.The tape came right to where the anomaly started.Ryan and Jack's conversation on the walkie-talkie comes over the loudspeaker.

"Jack, how's the sensor?" "Nothing came out. Just schools of sardines." "Hey, Jack, you're too noisy." "Ah, sorry." At this time, suddenly there was a voice that was not clear.At the same time, the large glass separating the studio from the recording room cracked and shattered with a horrible sound. Jack hurriedly stopped the tape recorder. Gordon picked up a shard of glass, his back flinching in shock.The glass is used for soundproofing, and its thickness is nearly three centimeters.And the glass shattered into pieces in the blink of an eye before their eyes.

"Is the volume too loud?" Jack turned down the volume on the volume control one by one. "What volume? There's no sound at all," said Gordon. "You said 'no sound'?" Jack snorted. "Stop being silly, Gordon. How long have you been here? This is Dolphin Studios!" Gordon blushed when Jack laughed at him. Dolphins' voices contain sounds that humans cannot hear.What we can hear with our own ears is only part of the sound made by dolphins, and Gordon knows that.It's just that since it can shatter glass, he imagined it to be some terrible sound like an explosion.In terms of seniority alone, Gordon is much older than Jack.But in terms of the ability to absorb new knowledge, Gordon always lags behind Jack.Also, he was always annoyed by Jack's blunt way of speaking.

"What? Did the dolphin's clack break the glass?" Ryan said. "Not sure. But something was barking loudly." "Jack, do you have any basis for saying this?" Gordon spoke in a slightly rambunctious tone. "according to?" "Biological basis." "Ha!" Jack snorted. "That's your major, right? Don't ask me!" Then you should talk less.Gordon muttered mentally. "I only know about machines. But it was the same in the morning. The instruments were all on the top, and the reason is unknown. But it is the same now. The instruments are all on the top, and the glass 'slaps' together!"

"How can this happen," Gordon said. "Is the sound of the sea veins so powerful? Jack, do you have any evidence that it was done by dolphins?" Gordon, who is always as bright and cheerful as the clear sky in the south, has a stubborn temper when he comes up.Jack noticed it, and he showed a troubled expression. "Dolphins? I didn't say dolphins. I just said that sound was put on tape." Jack typed on the computer keyboard and said. "I only understand the sound data. Except, if I say one thing, it's this: We recorded an unexpected 'sound'. But this is just a technician's point of view."

Jack's sarcasm made Gordon even more upset. "Forget it, instead of talking with your mouth, it's better to take a look." After speaking, Jack pressed the button, and the live conversation started again. "Gordon! You come on!" "What's wrong?" "Look at this quickly." It's slow. Jack slowed down further.The voice then became lower and lower, slower and slower.When the voice became inaudible, Jack turned his head back with a smile. "can you hear?" Ryan and Gordon listened intently.Jack slowed down even more.As soon as I heard a high-pitched "ding", the sound gradually decreased in pitch, which sounded like a strange sound of cloth being torn.High-frequency sound waves are inaudible to human ears, but if the tape is slowly turned, the frequency also drops.Jack turns the normally imperceptible sound into something "visible".

Looking at the waveform on the computer screen, Jack said: "Frequencies from 80,000 to 150,000 Hz..." "It's the audible range of dolphins." Ryan whispered. From 80,000 to 150,000 Hz is the sound frequency band that we can't hear at all. The upper limit of the frequency that humans can hear is 20,000 Hz. From 80,000 to 150,000 Hz, it is the sound that dolphins listen to every day. "Is it because of this sound that the glass shattered?" Jack said, reaching for the keyboard to stop the tape.But just before his fingers touched, something strange happened again.The sound of tearing the cloth just now suddenly became higher-pitched and disappeared in an instant.Ryan and the others thought it was Jack who had switched the tape back to normal speed, but Jack himself was looking at the computer screen, motionless and pale. "Hey, Ryan, can you believe that?" Ryan read the numbers on the screen. "1 megahertz? No... it's gone up again. It's 2 megahertz now." That is a figure equivalent to more than ten times the daily audio frequency of dolphins.Ryan was amazed. "What, the dolphins won't be able to hear you in that case." Ryan also looked at the screen.The waveform of the sound that has been converted into a graph is jumping above the coordinates, which is much higher than the place I am used to seeing when doing dolphin analysis. "Maybe something went wrong, I reversed the speed." Under Jack's operation, the slow-rotating tape speeded up again.At the same time, inaudible live conversations processed by subwoofers are revived.Jack confirmed the settings one by one again. "Hey, the measuring instrument is not working properly. How is your side?" It was what Jack in the boat said when he called Ryan.Jack, who was here at this time, immediately looked around.The sound was soft at first. "Hey, the measuring instrument is not working properly. What about your side? Hello, the measuring instrument is not working properly. How about your side? Hello, the measuring instrument is not working properly. How about your side? Hello, the measuring instrument is not working properly. Your side How about it?" "What's going on? I heard something." "What's going on? What did I hear. How's your side? Hey, the gauges aren't working. How's your side? Hey, what's going on? What's I heard. The gauges aren't working. How's your side? ?” The repeated voices seemed to grow infinitely.The same phenomenon that struck Ryan was repeated in the studio. "Hey! Jack! Stop the tape!" Ryan shouted, and his voice evoked endless echoes. "Hey! Jack! Stop the tape! Hey! Jack! Stop the tape! Hey! Jack! Stop the tape! Hey! Jack! Stop the tape! Hey! Jack! Stop the tape! Hey! Jack! Stop the tape! Hey! Jack! Stop the tape! Hey! Jack! Stop the tape! Hey! Jack! Stop the tape! Hey! Jack! Stop the tape! Hey! Jack! Stop the tape! " The panicked Jack didn't know which one to stop.Ryan hurriedly pried open the switchboard and turned off the power.The lights in the room disappeared along with the image on the computer screen, and at the same time, the mysterious looping echo stopped. "Is that the one just now?" Gordon said with a pale face. "Ah...it has become that abnormal situation again." Ryan's forehead was covered with cold sweat, and he fell on the chair all of a sudden.Jack didn't care about these.The booting computer was powered off, causing him to crash. "Lian! Don't move around, please!" Jack hurriedly turned on the power again and began to check. "Is the high-frequency sound wave level of the recorded sound too high? It exceeds the capacity, so the machine becomes abnormal." Ryan said while digging his ears. "Impossible. I lowered the level in advance to the point where it wouldn't run fast. Just in case, I also inserted the limiter 1 in the strong direction." After speaking, Jack suddenly twisted his neck and asked: "Wait. If there is an abnormality if the capacity is exceeded, then only high-frequency sound waves are enough, why are even irrelevant sounds involved?" This seems to be the idea of ​​a technician.Jack put his finger to his lips, looked around, and asked a more modest question. "...Why is our voice repeated?" "Uh?" Gordon didn't understand what he meant and blinked his eyes. "It's the sound of our speech just now!" Jack tapped his lips several times, "We didn't take the microphone, why did the sound just now keep repeating?" "Hearing you say that, it's a bit wrong." "Is it a ghost?" Jack lowered his voice.For Jack, who has stayed in the studio all year round, this is not the first time that the sound has been mixed with ghostly voices.If the reason is unknown, they will all be counted as ghosts, which is the habit of their technicians. Jack looked at Ryan.Ryan gritted his front teeth, which was his habit when he was meditating.Jack and Gordon waited for the sound of his gnashing of teeth to stop. "That's it..." After a while, Ryan finally spoke. "Jack, you play the tape again." Jack frowned. "Wait. Doing so will damage the machine, and the cause of the abnormality must be found out first." "I guess there is no effect on the machine." "how do you know?" "I want to try it." Ryan seemed to have an idea. "Got it. I'll play the tape right now." "Then turn the volume controls all the way to zero." "Then you won't hear anything." "Just do that. But just one... just set that high-frequency sound track to loud." Jack couldn't figure out Ryan's psychology, but he still started to prepare. "What happens then?" Gordon asked. "I don't know. So I'll try." Ryan looked serious.Gordon said to Jack: "Please lower the high-frequency sound wave a little bit than last time." Jack flipped the switch on the multi-track recorder again.In the track that recorded high-frequency sound waves, the noise of frying oil in the sea crackled, and the calls of dolphins were mixed in from time to time. "Jack, can you cancel the sound below 20,000 Hz that you hear now?" "Uh?" "I want to leave only the magnetic tracks of the high-frequency sound waves." Jack called up the waveform diagram on the computer and eliminated all the frequency bands in the audible range below 20,000 Hz. "it is good." Jack starts up the multi-track recorder again.The tape moves silently, yet the sound is there.They've dealt with this high-frequency sound for years, but now the silent world of sound is strangely frightening.Soon came the point where the level meter came to the end.The pointer of the meter has reached the red warning zone.It is still a silent world, however, the "sound" does exist. Jack and Gordon turned around.Ryan approached the table with the volume adjustment device lightly and slowly, standing next to Jack who was sitting.He put his hand on the fader which had only actuated one bar, then tapped Jack on the shoulder with his remaining hand and said suddenly: "Hello, Jack! It's a beautiful day!" As if the voice had been waiting there for a long time, it couldn't wait to start repeating. "Hello, Jack! It's a fine day! Hello, Jack! It's a fine day! Hello, Jack! It's a fine day! Hello, Jack! It's a fine day!  …" Ryan immediately turned the volume control to zero.The sound stopped, and the surroundings returned to silence. "Did you hear that?" Ryan asked back.Everyone nodded. "Now, where did you hear that voice?" "I...over there." Gordon pointed in the direction where Ryan and Jack were sitting. Ryan also pressed Jack to answer.Jack asked Gordon in surprise: "This way? Are you sure you heard it over a loudspeaker?" Gordon nodded vaguely. "I think so..." "Strange. I heard it from the side." After Jack pointed at Ryan, Ryan had a serious expression, but he finally couldn't help laughing. "Hahaha, I was joking just now, I didn't expect you to be fooled so easily." Gordon didn't understand what was going on, and looked puzzled. "Why, don't you understand? Let's do it again." Ryan faces the table and turns up the volume control again. "Hey Gordon, did you catch any fish?" "Hey Gordon, did you catch a fish? Hey Gordon, did you catch a fish? Hey Gordon, did you catch a fish? Hey Gordon, did you catch a fish? Hey Gordon, did you catch a fish?" Did you catch any fish?..." The sound starts looping again.Looking from Gordon's direction, because Ryan's back was turned to him, he only knew that Ryan's jaw was moving.In fact, Ryan was talking by himself.Understanding his mystery, Gordon was dumbfounded. Ryan pushed down the volume button, reducing the volume to zero, and his own voice stopped at the same time. "What, Ryan, forget it soon." "Hahaha. How is it? Did you understand this time?" "I did hear it from you, it's the same as what Jack said." However, beside Ryan, Jack, who had been looking at him, said to Ryan: "What the hell are you doing? Explain it to us." Out of the blue, Jack exposes Ryan to Gordon. "Ryan said just the first sentence. Then he said nothing, just moved his jaw." After being exposed, Ryan stopped playing pranks. "... Have you ever listened to your own recording?" Ryan said, "The voice of speaking is different from usual. The voice just now is not the same, it sounds like he is speaking normally. And this place is obviously There is a real feeling, and you can feel the voice coming out." Ryan touched his chin and throat. "Didn't you just talk?" Gordon didn't seem to understand the situation. "I didn't speak. What I said was just the first sentence, and who was talking nonsense after that. No, Gordon, I didn't intend to lie to you. It was just an experiment. What you heard was obviously me talking Right?" "Ah, that's all I saw." "Jack too?" "It does seem that Ryan is talking and his mouth is moving. But Ryan, what is going on?" "Through this experiment, I understand, first, the sound just now did not come from the loudspeaker. It has nothing to do with the machine." "I knew that. But why does it sound like you're talking?" "Wait a minute. Second, turn down the volume, and the sound stops. If the only high-frequency sound wave was played just now, then this phenomenon must be due to it. The question is, what is this high-frequency sound wave? Also, why The voice sounds like I am speaking? Where is the original source of the voice? It’s just the high-frequency sound waves, and there’s only that sound. It’s just 'it’ and my voice. That’s the point." Ryan paused for a moment, as if he was sorting out his thoughts. "...yes...for example, if I say 'Hey Gordon, did you catch any fish?', the sound is a vibration. The wave of vibration travels through the air, expanding in an instant to the entire room, to every Even under the table, you can't escape that sound wave. So, even under the table, you can hear 'Hey Gordon, did you catch any fish?'. Part of the wave directly vibrates your eardrums. So You just heard 'Hey Gordon, did you catch a fish?'. I vibrated my vocal cords and made a sound, which reached your eardrums in the next moment. When it reached you, I couldn't hear the sound. This is the sound world of a thousandth of a second because the sound wave has already been transmitted. However, the object is the sound wave, and it will return when it hits a wall. If you shout in a tunnel or mountain, you will understand it. Anyone in such a place can recognize it. Usually it is just difficult to confirm, but in fact this kind of thing is very common in daily life. Although the reflected echo is very small, it returns to me and your ears a little later than the first wave transmitted to your ears. This is the basic principle of sound. And what uses this principle is the echolocation of dolphins." Jack nodded vigorously and said to Ryan: "It's fine at this elementary level. We are not students who come to practice." "Okay. So, the echoes we experienced just now are incomparable in the mountains and in the tunnels. And, 'Hey Gordon, did you catch any fish?' To me, to you, It's exactly what I said. It seems that the sound is not reflected from the wall or the table. So, what is the reflection?" Gordon was still looking around, but the responsive Jack had already answered. "You mean, high-frequency sound waves?" Ryan nodded. "Have to analyze to have a say, but maybe the high frequency sound waves create a coral reef-like area all over the room ... It's not like a dome-shaped stadium that's empty in the middle. Like a sponge. Suppose sound waves form a sponge-like tissue, and we are in it. It catches the sound we make, the sound played by the amplifier, seals it in, and reproduces it one by one..." "Good. Well worth the parsing." Jack's eyes sparkled.Ryan continued: "Anyway, it wasn't dolphins. Because it's hard to imagine on a frequency level." "What's that?" Gordon asked.Ryan asserted categorically: "Broad-throated fish." "Did you meet the swallow fish?" Jack leaned out. "Actually, little is known about the phallus, and it's not clear whether they use echolocation. But they are deep-sea creatures. It wouldn't be surprising if echolocation evolved in a world without light. " Unknowingly, a smile appeared on the corner of Ryan's mouth.It's the kind of thing that makes a scholar's blood boil.Luckily, there is one in the lab of the live phallus.Investigating it may be a breakthrough in solving today's strange and extraordinary event.Ryan thought so. "Oops!" Suddenly Gordon cried out. Ryan and the others turned their heads in surprise, and Gordon said, "I forgot to pick up Billy," before rushing out of the room. A few hours later, Gordon's car returned with Hajiru and Billy, carrying the tape that Ryan and the others were eager to see.And it was this tape that Hanuri and Billy, who were pale-faced, wanted to show them right away. "Nothing at all." Haluku handed the tape to Ryan and said.His face was a little pale. "Uh?" "Nothing at all." "Are you saying it wasn't recorded?" Ryan asked. "No, it's on the tape. It's just that there's no squid." "You mean you didn't take a photo?" "No. How should I put it..." Haluku couldn't find a suitable explanation.Billy said from the side: "In short, take a look first, and then talk." "It's still serious." Jack said, "Let's take a look first." Seeing the video played, Jack was stunned. "No, there is really nothing." Ryan was even more shocked, he stood up from his chair. "How did this happen. There are so many! We passed through that school of fish!" Ryan should be surprised.There was indeed a wide-pharynx on the tape and it was not recorded.The camera was running all the time, and even when Billy let go of the camera after something went wrong, the camera was still running on his waist.Also, the camera continued to run as it criss-crossed the huge school of phallus, covering the surrounding area in large numbers.Therefore, it is impossible not to catch a single fish. In the end, the part where Hanuriku was chasing with the camera in his hand didn't capture anything.Looking at the video, it's obvious that Hanuri was trying to capture something in the sea.He zoomed in, desperately following something.But on the key screen, only the blue sea is recorded. Gordon replayed the fishfinder recording.If the testimony of Ryan and the others is accurate, then, the shadow of some fish should be detected around that time.Yet there are no traces here either. "Really..." said Gordon Mobile Chart Data, "the shadow of the fish was also observed, when Billy dived into the water. Even assuming it was a swallow fish, they went north while the dolphins were enjoying their lunch It moved away. According to this calculation, when the abnormality occurred, there was nothing in that area." Ryan started rattling his teeth again, but this time he couldn't seem to think of anything.Ryan sighed deeply. "No, I have no idea what's going on." Ryan then talks about what happened to Billy and Hanauri during their absence, and his assumptions about high-frequency sound waves. "It's not a dolphin, and it's not a wide-pharynx fish. If this is the case, then the owner of the sound does not exist. Who made that high-frequency sound wave? This question itself has been stranded." Billy remembered something. "Could it be a whale? Didn't we hear it in the sea? The sound of a whale!" "It can't be a whale." Ryan replied coldly. "why?" "Because whales are experts at low-frequency sound waves. It's like asking Gordon to sing a soprano. Whale low-frequency sound waves are said to be used for long-distance conversations. The slow fluctuations of low-frequency sound waves can be transmitted incredibly far. With that sound, whales can talk to their partners hundreds of kilometers away." "It's quite a distance." Billy frowned. "But if this is the case, isn't it still a dolphin?" "That's a sound that the dolphins themselves can't hear. For the dolphins, that sound doesn't exist." The conversation stopped here.Everyone held their heads and thought hard, and there was only a long silence that lasted.It was Billy who finally broke the silence. "If you say..." Billy picked up the paper and pen at hand, and slowly drew lines on the white paper. "You can draw such a straight line because you can see. If you close your eyes, you can't draw a straight line. But what happens if you close your eyes halfway through the line?" Saying that, Billy closed his eyes while drawing a line.When he opened his eyes again, the lines on the paper were greatly skewed. "Hey?" Halu laughed. "What do you want to do?" "To sum it up... no, that's a bad example. Let's say, sausage. It's on a plate and you want to pierce it with a fork. But the power goes out halfway through. But you want to eat sausage, so you pierce it in the dark." says It's messy, but you know the sausage is right in front of you. Try it a few times, and if you pierce the sausage with a fork, it's not surprising." "What do you want to say?" Ryan asked. "What I'm trying to say is that, assuming it's a dolphin, if it gradually raises its pitch, even if it doesn't hear halfway through, it will continue to speak. Sorry, I can't find a good analogy." "You insist it's due to the dolphins?" "I don't mean anything else. What else can it be except dolphins? Besides, I think of one more thing." "what?" "'Magic Sound Phenomenon'. Have you never heard of it?" All eyes were on Billy. "'Magic Sound Phenomenon'?" Ryan asked back. "Don't you know? It's been a long time ago. An Australian tuna fishing boat encountered strange things in the Indian Ocean." "never heard of that." "It happened off the coast of Tasmania, and the crew had unexplained auditory hallucinations, just like us." Ryan's expressions also changed. "The boat was out of control, the crew couldn't continue to work, they dropped their fishing nets and escaped from there, narrowly escaped death." "Why?" Gordon asked. "I don't know. It's said that they caught a strange thing. It's a mermaid, a dinosaur from the Cretaceous period, all kinds of rumors are flying all over the place. That topic has been raging for a long time, and our magazine also published it." "It is indeed very similar to our situation." Ryan said. "I've collected a lot of similar examples since then, mostly smaller scale, nothing as big as a tuna boat. There's been an astonishing amount of stuff like this dive, but there's been a lot of fake news. Even that tuna boat , the crew's testimonies were inconsistent and unreliable. In the end, it was accused of 'no scientific basis' and disappeared from the stage. Now, that incident has become a story on the same level as the jet plane that disappeared in Bermuda waters. Featured in a sci-fi magazine that worships the Loch Ness monster and UFOs. To be sure, this is an unexplained phenomenon. Now, because of its connection with the legendary Witch Rock 2, it is generally called the "magic sound phenomenon". Isn’t there an example of explorer Schliemann 3? If it is assumed that the “magic sound phenomenon” actually exists, it is likely to be a trace left by that kind of myth. If the legend is true, how to explain it?” "The mermaid lures the crew by singing...?" "Maybe it's based on a girl who lives by the sea and has a beautiful voice. It might be based on the sound of a dolphin, but it could also be..." Billy was getting excited. "...it takes courage to say these words before the great authority on dolphin research..." "It's okay," Ryan said. "Okay. That dolphin hunting sound..." "'Stun'?" "Yeah, the sound of shooting. Maybe some fishermen saw that for fear of making up stories like that." "Not bad." Ryan rubbed his chin and nodded. "In fact, according to some experts, could the 'magic sound phenomenon' be the ability of dolphins that are unknown to humans? In short, if the shooting sound is applied to humans, will there be a 'magic sound'? phenomenon'?" "But what's their purpose? Are they trying to catch us and eat them?" Gordon said. "It seems that there are also opposing opinions. But please hear me out first." "it is good!" Jack changed his crossed legs and straightened his back as if acting in a play.Billy continued: "What is the condition of the fish that encountered the shooting sound? Does it hurt? Is it painful? How painful is it? Perhaps, the phenomenon we experienced will also happen to them? You have come into contact with spotted dolphins several times, so from their For example, they have also tested humans several times. If during this period... we don't know, they tried out which frequency-modulated shooting sound should be used by humans..." Billy watched everyone's reactions.Everyone was sorting out what he had said in their minds. "So, the phenomenon of paper and sausage just now appeared. The dolphins made shooting sounds, but humans didn't respond. They kept raising their voices, but they didn't respond yet. Soon the sound entered a field that they couldn't hear themselves, but they could feel it They continued to make sounds. Soon the human beings panicked and became abnormal. Then they understood—that tone is a sound that humans hate. Even if they can’t hear it, seeing the other party’s annoying reaction allows them to master that tone. … Well, that’s all I have to say, then, I’d like to ask the teacher’s opinion.” Ryan stood up at the request. "Indeed. There may indeed be such a thing, that spotted dolphin has plenty of time and opportunity. In fact, they sometimes accost at a frequency close to ours. Don't know what they're talking about, of course. It's just human contact Dolphins have been doing this for a long time. That is the action of them learning and imitating human pronunciation. Anyway, dolphins are sound experts, and the sounds they master are equivalent to symphonies—if human language is compared to If it's a harmonica." "But if you let me say..." Gordon said, "What are they for? The shooting sound is a function for hunting. If it is used on us, is it going to eat us? Or treat us as an enemy?" "Suppose they're just games?" Billy said. "Dolphins like to play, don't they?" At this point Ryan began to retort. "Billy's opinion is very interesting. But you have seen the shooting sound of dolphins, and it is very short. It is very hard for them to make a strong sound for a long time. But last time the high-frequency sound wave lasted quite a long time. Time, and the frequency is too high. We have been analyzing the sound of dolphins for many years, and the value has never been heard before. It's like... there appeared a sprinter who ran a hundred meters in only two or three seconds. It's like something Did you make a mistake?" After speaking, Ryan looked up at the sky. "Yes, there must be something wrong, this high-frequency sound wave..." The next morning there was a call from the weather station in San Eleanor.The staff on duty conveyed Ryan's phone number accurately.According to observers, the pointer of the seismometer moved two or three times in the past few months, all of which were micro-shocks that the human body could not feel, and the source of the earthquake was in the far north.Before and after Ryan and the others encountered the abnormal situation, there was no earthquake. "However, there have been cases of deep-sea fish floating up again." The observer said.Recently, the news that deep-sea fish frequently floated to the surface of the sea also reached them. "It's best to step up your vigilance." Then the observer thanked Ryan for their report and put down the phone.
