A low hum in 57702, USA
On and off very low frequency, almost felt by my ears more than heard like a car in the distance cranking the bass. It's on and off, no more than 4-5 seconds on, and off briefly. I only hear it during cool nights- only noticed 1 or 2 times this summer, but starting again with cooler weather. Around 55 degrees seems to be the max temp. Wondering if it isn't something with the city utilities or power company. 100 percent sure it is only present with cool weather.
