Why is it quiet around after the heavy snow?

To sum up, because of cedar, the gap is large, fluffy and porous. Sound travels everywhere. Generally, when encountering obstacles, some sound waves will be absorbed, and the other sound waves will return. However, due to the loose texture of snow, the gap is large, fluffy and porous. After the sound wave enters the gap, it fluctuates back and forth, weakening the sound wave and finally disappearing, so it is quiet after the heavy snow. It is caused by the structure of snowflakes.

Because the loose and porous structure of newly fallen snow can make sound waves reflect many times, thus reducing the sound.

In addition, there are objective factors. Of course, the right one is the last one. I'm just making a blind analysis of my point of view here, as a joke: 1, there are few people on the road, driving slowly and making little noise. Because of the weather, my mood is relatively calm.

2, this is a psychological problem, people's inner feelings have changed because of some circumstances. Just as color can achieve this effect, most warm colors make people feel excited. On the contrary, cool colors make people calm or calm. Another possibility is that snow often returns to the ditch to remind people of their thoughts; Rain will dispel some people's sadness.

There are fewer people on the road.
