As the title says, why is it so loud after it rains? I feel like after or during rain I can hear every car on the road in a 3 mile radius. Sound seems to travel farther and I can even hear people talking down the road.
In: Earth Science
Sound travels by a wave moving through the air (or other substance). The denser the air, the easier sound travels through it. When it rains, the air is typically cooled down at least a bit, and air is denser when it’s colder.
Also wet roads are noisier than dry roads because each tire lifts some water drops which then make some noise when they fall back down
I suppose the flip side would be the quiet after it snows….I’m guessing snow absorbs more sound?
