Chapter 31, Hearing Aids!

In fact, in nature, echolocation is a very common method, for example, the most famous bats, toothed whales, seals, sea lions have such a magical ability, they can through their own ultrasonic waves, to detect the environment, especially bats, he can do rapid flight in the air without touching any obstacles, and even through this ability to directly in the air to prey, catch those smaller pit insects, its echolocation skills have reached the point of superb.

Although scientists have also done targeted research on this phenomenon in nature, and have developed artificial devices such as submarine sonar, these things are undoubtedly insignificant for Yi Xiaotian's upcoming things.

These man-made devices all have a variety of shortcomings, one of which is that they are too noisy.

This is the biggest flaw for Yi Xiaotian, who is paranoid about his pursuit of perfection.

Due to the limitations of the hardware equipment, he was unable to conduct any detailed research on the device he was going to make, but it did not affect his research on the software equipment.

In his opinion, since the hardware is a problem that cannot be solved at this stage, then try to solve the problem of its software.

There are many programming languages on the earth, but Yi Xiaotian knows that the most basic information that computers can accept is 0 and 1. So, can you use what you have learned on Earth in this world of using patterns, and weave these patterns into something like a computer language?

This is not a fancy idea for him, because he has been focusing on the research of the world's simplest and most common new energy block in the past two years, so he has already learned a little bit.

These most basic things are enough for him.

In his previous life, as a scientist who studied artificial intelligence, there is no doubt that he naturally has his own opinions on the human brain.

The ear is the main organ that people can hear sounds, and the ears can hear sounds, and there are three main parts involved: the outer ear, the middle ear, and the inner ear.

The outer ear is the pinna, and its role is to collect, capture, and transmit sound waves to the middle ear. Sound is a vibrational wave that can be enhanced by physical shapes, which is why many animals have more sensitive hearing than humans, because their auricles are usually much larger than humans.

The function of the middle ear is to convert sound waves into mechanical waves, and after the external sound is transmitted to the ear, the eardrum in the ear will vibrate, thereby driving the three hearing ossicles located in the middle ear to vibrate at the same time, so that the sound waves are smoothly converted into mechanical waves.

The vibrations then pass through the fluid in the spiral cochlea, causing the tiny auditory hair cells in the cochlea to move. Auditory hair cell shifts detect movement and convert it into chemical signals acceptable to the auditory nerve. Eventually, the auditory nerve sends hearing information to the brain, which translates it into sound.

This is the whole process of input of sound information from the outside world.

Yi Xiaotian has accumulated a good amount of programming and the work went smoothly, and it took more than three hours to finally complete the editing of the core algorithm of the hearing aid before dark.

When compiling this driver, Yi Xiaotian made a bold inference, and he found a very interesting situation, if he used this kind of technical means, he could actually hear the heartbeat of others from two meters away, which is really an interesting thing.

Generally speaking, the frequency range of sound that a normal person can hear is between 20 hertz and 20 kHz. But in reality, this is a limit that most people are in a segment of, and very few people are able to touch the edge of these frequencies.

In addition, hearing is also related to age, and as we get older, our perception of high-frequency sounds decreases, for example, sounds above 16 Hz are basically inaudible.

According to the classification of sound waves, those below 20 Hz are called infrasound, while those above 20 kHz are called ultrasound, both of which are not perceptible to the human ear.

And is this actually the case?

It turns out that some blind people can completely break through this limit and directly praise the forbidden area of human sonic waves or ultrasounds.

For example, an existence like Jingjing Girl can hear her own heartbeat ten meters away without using a hearing assistive device, and I don't know what to do if I bring the device.

He was a little curious about what it would be like when Jingjing got the hearing aid he had made, but at the same time, he also had some guilt in it.

As the saying goes, take a peek and see the whole leopard. The moment he stood in front of the delicious fragrant hot pot restaurant in the morning still terrified him.

His math is good, and he can estimate the amount of dog meat used in a hot pot restaurant for a day, at least 600 catties. That's a staggering number!

There are five months in winter in Huayang District, if a month is counted as 30 days, five months is 150 days, 800 catties a day, 150 days is 120,000 catties, you must know that a large dog is only 120, 130 catties!

This is just a hot pot restaurant, you must know that in Huayang City, there are more than a dozen such hot pot restaurants, this is large, and those small hot pot restaurants don't know how many.

It was a staggering number that he didn't dare to count.

He was a little scared and a little guilty, because he didn't know if he could find Scar's dog.

Because the dog meat hot pot industry in Huayang City, as a characteristic industry in Huayang District, I don't know how many people rely on this black industry chain to survive every year.

Because he was a little afraid that what he had worked so hard to find was most likely the bones of Scar.

So he is eager to develop an instrument that can be used by Jingjing to replace Scar navigation, and of course, the dash cam on Liu's father S300 is naturally part of this plan.

Because Yi Xiaotian has been working in Liu's father's place for a long time, and he often takes out some more practical small things, many good things in Liu's father have been picked up by Yi Xiaotian.

For example, the motherboard on this wind-type shuttle is one of the few good things in Liu's father.

The Hurricane is one of the most popular types of shuttle cars among young people in the Federation in the past two years.

Streamlined design, one-piece body, full of science fiction, the maximum speed can reach 300 to 500 kilometers per hour, which is simply irresistible.
