Most of the time, I live on the 3rd floor of a 16 story high-rise. The condo building is cast concrete with brick on the outside. It is the quietest place I have ever lived. I was surprised when I moved there at how quiet it is. There are 250 units in the building, and I seldom hear my neighbors. I don't hear traffic, in the dead of the night if you listen carefully you can hear the passing freight trains a mile and a half away - but not the subway station less then half a mile away.
I woke up this morning to the sound of thunder and rain. It is kind of loud if you are not use to it. I am at my parent's house for Thanksgiving. We are in the semi tropics and it rains (it takes liquid sunshine to keep Florida green.) I dare not look at what the thermostat is set, likely in the high 70's or low 80's, old age and decades in a semi tropical environment and the house is kept rather warm and humid. So I have my door closed, a window open and a fan has been running in my room constantly since I have been here. I bought the fan in self defense a decade ago and it has been a constant presence in the guest room ever since So I can hear the hum of the fan. Not something I hear at home, where I control the temperature, set year around in the low 70's in the condo (the new climate control system in the condo switches between heat and air conditioning automatically - I don't have to touch the controls for months on end.) Because of the design if the system in the condo, I can't hear it run unless I am standing next to the utility closet in the living room.
It is still early, maybe I will lay back and listen to the rain.
