Every time I go camping and it starts to rain, I can't sleep anymore because the raindrops that fall on the tent causes a really loud and annoying sound. Is there any technique or tool to avoid or at least decrease that sound?
To me it's one of those sounds that can be soothing initially, but start to grate on you after hearing it for hours. You could try ear plugs. I don't wear them because I like being able to hear my surroundings, but I often see people camping with mp3 players, so not everyone appears to feel the need to be aware of their surroundings!
