Do sound waves travel differently in highly humid air than in dry air? Can you share any stories?

Sound waves are pretty close to independent of a gases density or pressure. However, sound waves travel faster in a lower molecular weight gases. This would include humid air which will have a higher molecular weight than dry air.

So that's why it's so muted in the thick fog, sound propagation is affected by absorption in the water itself.

I grew up in a desert and sometimes sounds can be heard from miles away, yet after a rain these sounds only travel half or less as far, and in the fog they really don't travel at all, even shouts are deadened within yards of their origin.

They travel faster in dry air than moist air....

I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
