On the 10 hour drive back from the Outer Banks I discovered an annoying squeak somewhere on the driver's side of the car. I couldn't find the source. Finally at home, in a few hours I realized the noise came inside with me and was in my head.
I've lost much of my hearing, I think mainly from loud jobs especially on older tugboats. What hearing has been lost is replaced with a constant blend of peepers, cicadas, and rushing water, all punctuated with intermittent beeps and squeaks.
To keep what peace I have I cannot fight these sounds or try consciously to ignore them. What works best is to welcome them, occasionally be amazed they are there and always be aware that sounds I hear may or may not be actually out there or only in my head.
