Why it gets so quiet after the snow I FOX31 Denver

GOODLETTSVILLE, Tennessee (WKRN) – Winter weather has turned mid-Tennessee and southern Kentucky into a snow globe. Snow does more than just look pretty; it acts as a very efficient noise absorber.

The reason why snow absorbs sound waves so well is because of its structure. Snow is made up of ice crystals, which have a space between them. These open spaces absorb sound waves, creating that serene calm that occurs right after a snowstorm.

A study found that just 2 inches of snow can absorb 60% of sound waves. The lighter and fluffier the snow, the better it will absorb sound waves.

The calm of snowfall is something you only see with fresh snow. Once the snow begins to melt, the opposite happens. When snow melts, refreezes and turns to ice, it can actually get louder.

Ice reflects sound waves and sends them back to your ears. Then this serene calm disappeared.

A winter storm blanketed parts of the south in snow, freezing rain and sleet on Thursday, bringing roads in Tennessee and Kentucky to a standstill as the system made its way through the Appalachians to the mid-Atlantic and northeast. is.

Nashville saw 6.3 inches (16 centimeters) of snowfall on Thursday, shattering the city’s previous Jan.6 record of 4 inches (10 centimeters) that had been set since 1977, the National Weather Service reported.
