Scenario...dystopian civilization forced to build a city in the canon of a huge waterfall (think Iguaza Falls or Victoria Falls) to survive. city is several levels tall, suspended over the river below enough to allow for water rise but still access the water.
I've addressed issues of constant moisture in my plotting, but the one thing I have not yet addressed is the affect the constant rumble of the falling water on the inhabitants. I can have noise filters designed for indoor situations, but obviously there would still be people going about outside, and that sound would be always present there. I know people listen to waterfall sounds as white noise for sleeping/relaxation...but likely not at the volume this would create, and not on a 24hr a day basis. Thus I'm trying to determine what the effects of this might be on people...so that I can either incorporate that into the plot, or design cultural means for them coping with it (ear plugs, healthcare designed specifically for symptoms etc).
If anyone has any thoughts...or has suggestions for a direction for more specific research, I would appreciate it.
