The science behind the weather - Why it turns quiet when it snows outside

Have you ever noticed that when it snows, the world outside falls silent?

It's because of the delicate structure of a snowflake.

Sound travels in waves and needs to vibrate molecules of whatever it’s travelling through in order to be heard. Snowflakes, however, have holes and gaps in their structure. This reduces any vibrations, which helps dampen sound and reduces noise.

So next time it snows, why not listen to see if the world around you has fallen silent?
