don't call me singer

Chapter 676 Song of the Sea
Under the blue sky and above the blue sea, a white catamaran cut through the sea and headed south again.

The voyage of this trip will go all the way south to Vietnam, Indonesia, Sumatra, Indonesia, and cross the Strait of Malacca to the Indian Ocean.

And this route was Zheng He's first voyage to the West.

To some extent, Gu Xiaobai is following the footsteps of another self.

The last trial voyage mainly tested the overall performance of the hull, mechanical equipment and the performance of the ship itself.

But this time, Gu Xiaobai will test all the instruments on board.

In addition to the original equipment of the Zhongjun before Gu Xiaobai took over, Gu Xiaobai also installed more equipment on board.

Many of the transformations are very difficult, not to mention the expensive equipment, and even many of the equipment are not finished products at all, and Gu Xiaobai needs to customize them. Fortunately, Gu Xiaobai has money again.

At this moment, Gu Xiaobai was sitting in the room behind the cab, reading a book quietly, until Jiang Hailong came in: "Xiaobai, those underwater acoustic transducer arrays you have been tinkering with have been adjusted. Do you want to try it?"

Gu Xiaobai's eyes lit up, he stood up, walked to a console behind the cockpit and sat down.

Beside, a staff member looked over curiously.

This thing looks like a sonar, with complex graphics displayed on the screen.

But isn't there already a sonar on board?Why did you install another one?
"What is this?" Wang Guanshan approached Jiang Hailong and asked in a low voice.

"You still don't understand." Jiang Hailong ruthlessly despised Wang Guanshan, "This is a full-band high-fidelity underwater acoustic transducer system, very complicated..."

"Hey, what's on the boat, and what I don't understand? Isn't this just a sonar?"

"Sonar? This thing is not used as sonar." Jiang Hailong pouted, "So you don't understand..."

"Why don't you tell me why I don't understand?" Wang Guanshan still refused to accept.

My old king has roamed the rivers and lakes... No, I have been roaming the oceans and seas for decades, is there something I don't understand?
"This is a sonar." Gu Xiaobai interrupted the bickering between the two, "I used the existing underwater acoustic transducer technology to build a complex array myself, using low-frequency sensitive flexural transducers and The low-frequency resonator should deal with the frequency band of 10-1000 Hz, use the composite rod transducer and the circular tube transducer to deal with the frequency band of 1k-10k Hz, and then use the piezoelectric transducer to deal with the frequency band of 100k-1M Hz, and then use thick Membrane piezoelectric perforated plate, which can deal with the frequency band above 1M to 100M Hz...By integrating their signals and reorganizing the signals, the sound in seawater can be restored to the greatest extent..."

Wang Guanshan: "..."

A sonar, so complicated?

You must be lying to me!

What are you talking about?Why can I understand every word, but I can't understand the combination at all?

Jiang Hailong: "Look, I said you don't understand."

Don't believe me, brother Jiang, you're at a disadvantage.

Do you feel that you are particularly ignorant and uneducated?
The so-called transducer is actually an electroacoustic transducer, which converts electrical energy into sound, or converts sound into electrical energy.

To put it bluntly, it is a microphone or a speaker.

But this one is designed for use in water.

Since transferring the research field to hydroacoustics, Gu Xiaobai has spent almost all of his time in the design and manufacture of this set of underwater acoustic transducer arrays in the past month.

Now it's finally basically done.

In the next month, he will continue to improve the algorithm and debug the equipment.

Seeing that Wang Guanshan still didn't understand, Gu Xiaobai said, "You've seen many car owners who would transform their trunks into subwoofers, and use them while running."

Wang Guanshan has a picture.

"Imagine, replacing those subwoofers with the best HIFI equipment in the world, and then amplifying them hundreds of times, and installing them on the Zhongjun."

Wang Guanshan understood.

Wait, what the hell am I...

Are we a boy with a sports car who moves all the way?
No, the boat runner!
To whom shall we sing?

Do you want to chase the cargo ship and play songs for them?
Hey, don't run away, listen to my subwoofer!Sounds good!Is Lao Tzu handsome?Is Lao Tzu rich?

It's been decades, and I haven't seen such a rustic country!
Wang Guanshan suddenly felt that he was simply a mohawk with yellow dyed hair, wearing leather pants, wearing earrings, driving a special low-B remodeled sports car, and a high-profile demolition boy on the street!
"Oh oh oh... I see, the sound made by the previous bell and drum qin is the sound made by this set of transducers!"

Wang Guanshan said.

No wonder Zhongjun can make such a loud sound. With such a set of audio equipment, how can it not be loud?

"No..." Gu Xiaobai wanted to say that it wasn't, but after thinking about it, forget it, let him think so.

In fact, at that time, this set of equipment had not been installed yet.

Jiang Hailong showed a superior smile.

You don't understand the miracle of our Lord Zhong Jun.

It's okay, I don't understand either.

As long as I understand this set of underwater acoustic transducers, I'm much better than you.

And this set of underwater acoustic transducers almost covered the entire outer shell of Zhongjun.

its price...

The helicopter that fans gave Gu Xiaobai as a gift cannot be compared.

I also made money thanks to "Goodbye Boy", and the income from the new album is also very good.

Otherwise, Gu Xiaobai will become "Bankrupt Youth".

The new album "Youth · 306" will soon become "Poor Force · 306".

At this moment, the initial debugging was completed, Gu Xiaobai took out the earphones, put them on, and closed his eyes.

In an instant, a grotesque world rushed over.

The ocean is a world of sound.

In this vast ocean, light can only travel a few hundred meters at most.

In the ocean below 400 meters, it is pitch black.

But the sound can be transmitted tens of thousands of miles.

In the air, the speed of sound is only more than 300 meters, but in water, it is four times its speed.

Therefore, many creatures living in water have evolved a set of talents for positioning and communicating through sound.

But since the scope of human activities spread in the ocean, the ocean has become extraordinarily noisy.

At this moment, the algorithm of this system has not been fully debugged. The two sets of super-large, ultra-wide-band, ultra-sensitive arrays distributed on both sides of the hull are just passing all the received signals to Gu Xiaobai's In headphones, there is no filtering, no separation, and no processing.

Just like the sounds of nature.

In this world, there is nothing better than the human brain to distinguish sounds.

No matter how complex the sound environment is, humans can accurately locate the sound they want to locate.

And among human beings, perhaps there is no one who can be more sensitive to sound than Gu Xiaobai.

And this system is so sensitive that it can localize the sound to an incomparably far away place.

In an instant, Gu Xiaobai felt that he had sunk into an infinite world.

It is a wider, three-dimensional world than what can be seen visually.

Gu Xiaobai's perception seems to be extending through sound, extending...

The first thing that caught Gu Xiaobai's attention was the sound of a siren that was extremely low, like a whistle that was dozens of times lower.

"W...U————————————"

A deep voice, like a long, long trombone, blows in your ears.

This kind of sound is almost close to the limit of human hearing. The ultra-low frequency sound makes the whole body vibrate, causing an uncomfortable feeling of flustered and throbbing.

This is the sound of the warship's active low-frequency sonar.

All the voices that Bigu Xiaobai had heard before were deep and shocking.

Makes one's heart shrink.

Compared with it, the deep drum sound of the big drum is nothing.

In fact, the sound of this warship is just one of the countless noises in the sea, but the unique low-frequency sound immediately captured Gu Xiaobai's attention, allowing him to separate the sound from the background .

The human brain is very magical. Once the attention is focused on a certain sound, other sounds can be ignored.

And that voice seemed to be amplified, amplified.

Gu Xiaobai's consciousness, following the voice, was instantly positioned hundreds of kilometers away.

There, there is a warship sailing at sea.

Its propeller made a rattling sound.

Its bow oppresses the waves, splitting them like a sharp knife.

At that moment, there seemed to be countless particles gathering from all directions, and a blurry picture appeared in Gu Xiaobai's mind.

A huge warship rides the wind and waves and travels all the way.

Then, Gu Xiaobai's consciousness was attracted by another voice.

They were loud and short-lived, not nearly as deep or as long as the Navy's low-frequency sonars.

They are like tinkling music boxes, you can only play them after you play them.

This is the sound of civilian active sonar.

Civilian sonars with different frequencies seem to form rows of beating notes on the frequency spectrum.

Dispersed in time and space.

Gu Xiaobai's consciousness jumped on these notes, and suddenly another voice captured his attention.

Ethereal, melodious, high and low, like a singing voice...

whale!It's the sound of a whale!
In the deep sea, below the surface of the sea, the current is surging and the sound is rushing.

Beneath all kinds of noise.

The Navy's low-frequency active sonar, like kick drum and bass, laid out a layer of bass.

The rattling sound of the propellers knocked out dense drumbeats.

The sonar for civilian use is like a chord laid on top of the bass.

And a whale, in the accompaniment of the sea, sang a long song.

Gu Xiaobai closed his eyes, his consciousness gathered in the direction of the singing voice.

He heard no running water, only the singing of the whales.

But in his mind, there was still a blurry image, which was slowly outlined.

A huge whale sank more than ten meters below the surface of the water, singing quietly.

It is like a singer in the deep sea, a superstar in the ocean.

It is sung so earnestly and so focused.

Although it doesn't know who is listening to its song, it does know that there are countless creatures under the water who can hear the sound.

Of course, maybe it didn't expect that at this moment, there was a person listening to its singing, and even humming softly along with it.

There are some melodies, very soft and beautiful.

Music is also a kind of science, and everything in this world is determined by science, such as the Fibonacci sequence.

Whales don't understand any music theory, but they obviously evolved the same aesthetics in the same environment as creatures on earth.

Gu Xiaobai hummed softly as he listened.

In many clips, he also added his own interpretation.

It's a pity that the current transducer array has not been fully debugged, and now only the receiving array has been debugged.

Otherwise, he could have joined the show.

But that's fine too.

He can quietly enjoy the performance of this artist in the deep sea.

This is a very long song. Although Gu Xiaobai couldn't understand what it was singing, he could hear its emotional changes.

Sometimes low, sometimes high.

Suddenly, it sang to a place where it seemed to be happy, and laughed "giggle".

No, perhaps to the whales, it's not a laughing matter.

But that funny, funny laughter made Gu Xiaobai laugh too.

My whole mood felt better.

After a long time, he slowly took off the earphones, opened his eyes, and let out a long breath.

The sound in the sea is intoxicating.

He almost listened to it all the time.

It turns out that there are so many beauties and wonderful things in this world that you can't see or hear.

"What are you listening to?" On the side, Wang Guanshan and Jiang Hailong were puzzled, why did Gu Xiaobai listen and sing?
Gu Xiaobai thought for a while and replied, "Song of the Sea."

The song of the sea?

Wang Guanshan and Jiang Hailong looked at each other.

They had no idea what was going on in Gu Xiaobai's head.

Perhaps, the brains of scientists and artists cannot be joined by ordinary people.

Beside, the sonar operator looked sad.

What's so good about the sea, I used to listen to it every day, and I almost threw up, okay?
Fortunately, there is no need to listen to the sonar now, just look at the screen directly.

I used to be on a submarine, I heard it late one day...

Just thinking about it makes me want to throw up.

"Old Wang, do me a favor." Gu Xiaobai said to Wang Guanshan.

Wang Guanshan was taken aback.

A few minutes later, according to Gu Xiaobai's order, Wang Guanshan made the boat start to move fast and slow.

Everyone on the boat was almost dizzy.

Wang Guanshan was also a little dizzy.

What are you doing!
Jiang Hailong was even more helpless, thanks to my electric drive, otherwise you would have disabled my engine!
However, there is no way, and now there is only one way to join the chorus of the ocean.

At the rear of the Zhongjun, the huge propeller was rotating at different frequencies, making different high and low sounds.

In addition to the click of the propeller, another piece of music merged into it.

Few people in this world know.

What is the "black square formula", in fact, this propeller is a musical instrument.
