Cicadas swarming the tree outside my window.  The decibel level has increased significantly. I would imagine this is not good for your high frequency sensitivity. Took a short soundwalk to record them. There are two "notes" that you hear and you can see them in the frequency analysis. There is one lower note between 1 and 2.5K and one more shrill between 3  and 6K. If you are subjected to this for hours it must have an impact on that frequency band. As you can see it goes up to 20K in the "mosquito" range and younger ears can probably hear that. It must be painful.
