My thought on the general "loudness" of cold months was due to reduced noise blocking or absorbing greenery like tree leaves, grass, etc. Which is then altered by a significant snowfall leading to sounds being softened again.
- ffsm8 2y agoShouldn't that be an inverse relationship though? Without leaves on the trees you should get less reflection, consequently more of the noise should radiate upwards. Unless you're standing at the other side of a bush/greenery. In that case it definitely absorbs a lot
- CrazyStat 2y agoLots of small unaligned surfaces, like leaves, scatter the sound and make it interfere with itself. Reflection only makes the sound louder if you have large smooth flatish surfaces.
- Modified3019 2y agoAh, I had never considered the interference aspect of sound reflections
- CoastalCoder 2y agoI want to make a joke about the "three leaf" problem in acoustics, but I can't find a way to make it funny. Dang.
- kylebenzle 2y agoHN is becoming worse and worse everyday :(
- CoastalCoder 2y agoAssuming your comment is serious (rather than some quip), I think what we're seeing is differing visions for HN. One group (me included) enjoys some levity, as long as it's high quality and doesn't get in the way of substantial discussions. Another group would prefer that HN avoids that entirely. It mostly seems like a matter of taste / preference, so I'm not sure how we can come to one kind on this, shy of seeing the pro-humour approach clearly hurting the site.
- batch12 2y agoUsually I see high quality humor make it through. The low-effort Reddit quips get cratered.

- tomrod 2y agoYou made me chuckle. Mission accomplished.
- xattt 2y agoThe volume of water flow should/would also vary at different times of the year, based on how much the water table is loaded. Not sure how much of this would be complimentary to the acoustic effect of temperature. Either way, it’s not a simple single-solution explanation.
- BurningFrog 2y agoMy guess is that frozen terrain is harder, which reflects more sound and makes hitting it noisier.
- xerox13ster 2y agoCold air is also more dense, less momentous, and can transfer sound energy more efficiently between particles than hot air where the particles are spread out and have their own momentum to maintain rather than the sound's.
- soulofmischief 2y agoNo one here has mentioned temperature inversion [0] which is responsible for a lot of the cold-induced amplification perceived in urban areas. It's quite a fascinating effect.
