A low hum in U.S.A., Chapel Hill
A low-frequency, usually "throbbing" hum. The amplitude changes a bit, at a frequency of about 2 Hz. I hear it constantly in my house. When I go outside, I often hear other mechanical sounds (traffic in the distance, airplanes, construction vehicles, lawnmowers and other engines), but the hum is difficult to hear outside with all of the ambient sounds. Yes, it's driving me nuts. I started noticing it about 2 years ago. Thank you so much for taking a scientific approach to this problem.
