Let it snow...


Let it snow...
A quick lesson at this hour...so, why the world seems quieter when it snows?
The characteristics and age of snow can affect how sound waves travel, dampening them in some cases, or enhancing them in others. For instance, people often notice how sound changes after a fresh snowfall. When the ground has a thick layer of fresh, fluffy snow, sound waves are readily absorbed at the snow surface, dampening sound.

However, time and weather conditions may change the snow surface. If the surface melts and refreezes, the snow becomes smooth and hard. Then the surface will help reflect sound waves. Sounds may seem clearer and travel farther under these circumstances
