Why does everything get so quiet after a snow fall?
Because Freshly Fallen Snow Absorbs Sound
Just like you would see in a room full of sound-absorbing foam, snow dampens the sound waves, allowing you to hear less. It takes as little as an inch of snow to see this silencing effect take place and it is more obvious when the snow coming down is light and fluffy.
As a general rule, colder temperature increase air density which makes it harder for sound waves to travel. So when the temperature drops, it can make everything sound quieter since sound waves are generally travelling more slowly, especially in the presence of big fluffy layers of freshly fallen snow trapping all those slow-moving sound waves.
