Why does the wind screech when it passes through a narrow gap?

There are many sounds in the world, such as the sound of birds, cars, people talking, and the crying of children. These sounds pass through our ears to form the wonderful and beautiful language of this world. Because of these different voices, our understanding of the world is also more profound and full of unknowns.

Some of the sounds may seem strange to us, but there are different scientific principles in them.

However, what we are going to talk about today is the question of wind sounds, which are usually said to be felt, but sometimes we ignore a sound. Because when the wind blows, we rarely notice its sound, but in the more bad weather, such as when it is windy and rainy, the wind will also bring us different sounds, such as the rustling of trees being blown, which is a way of expression. <>

So why does the wind rattle when it passes over some places, it's because of the air currents. Because in the case of a high wind speed, the greater the resistance in the air, the sound brought by different resistance will be different, and with the resistance will produce a fluctuating frequency, and our ears can accept this frequency, thus bringing us sound. Depending on the situation, different sounds will be generated, and in some crevices, when the area is relatively small and the wind speed is relatively large, the resistance will be great when passing through, so it will make a loud noise.

It's not just in the long gaps. In other places where the force area is relatively limited, this will also happen.

When the wind is stronger, we can directly feel the sound of the wind blowing, and generally at this time, the weather outside is relatively bad, so pay attention to safety. Because this situation is generally windy, or a precursor to rain, it is necessary to go indoors in time to take shelter from the rain. There are many kinds of sounds in nature, in addition to the sound of the wind, what are the stranger sounds?

Because when these winds pass over something of a special nature, they form a vortex of air and produce vibrations.

When the wind passes through the gap, it does have a lot of movement, and the finer the gap, the louder the sound will be, because when the wind passes through the gap, the acceleration of the air flow adds the violent vibration of the particles in the air, and the induction of the eardrum, that is, the sound of sound.

Because the wind creates friction as it passes through the narrow gap. The narrower the gap, the greater the friction and the louder the sound will be.
