First of all, let's learn how the sound comes from. We are most familiar with human voices, and then the sound of horns. Both of these sounds are made by an object pushing air at different frequencies. Sound is driven by sound, and speakers are driven by paper pots. Energy source: the human voice comes from the burning of glucose in the vocal cord muscles, and the speaker draws electricity from the coil behind the paper basin. There are many reasons for sound, because air is driven by different frequencies. The higher the frequency, the higher the sound; Low frequency, low sound. The so-called frequency is the number of times the air is pushed in one second, and the frequency is equal to 200, which means that the air is pushed 200 times in 1 second. So when mosquitoes and bees fly to our ears, we can hear different sounds, which shows that mosquitoes and bees push air at different speeds with their wings.
Now let's analyze how the wind came from your door. This is the case. When the air is pushed, it is generally pushed by other objects, but on the other hand (physically speaking, it is a conversion frame of reference), when the air blows to the prohibited objects, it can also be understood that the air is pushed and sound waves can be emitted. So these rumors are that the air is blocked by the cement column of the door frame at the door, and at the same time it rushes forward desperately. In this way, a state of being pushed repeatedly is formed, and sound waves are emitted.
To solve this problem, it is impossible not to let the wind blow here. The general solution is to add diversion things, such as soft door curtains and soft plastic curtains, where the wind rushes in, which can convert the kinetic energy of the wind into heat energy and dissipate it, thus effectively reducing the noise caused by the wind.
Having said so much, I hope it will help you understand the voice a little.
