The quiet of Lapland: why snow softens sound

When there is plenty of snow, it acts like a natural sound absorber. There is a physical reason: snow crystals form a porous structure with many small spaces filled with air. These pores absorb sound waves instead of reflecting them. Fresh, loose powder snow has this effect particularly strongly.

Unlike hard surfaces such as asphalt or water, which reflect sound, snow absorbs it. Sounds echo less and do not carry as far.

The surroundings may also become quieter: cars travel more slowly or not at all, fewer people are outside, and some animals are less active in winter. This reduces the sources of noise as well.

Fresh snow can make the world feel muffled and still, almost as though wrapped in cotton wool.
