Very low pulsating rumble. Not unlike a distant diesel engine. I used to live near an alloy plant that had cooling towers with a very similar sound but this is much lower in frequency. The vibration that comes with the sound is itself more intense when I have a cold or allergies. The tone doesn't change, nor the volume. The frequency of the hum changes around 20hz up and down from the 200 at my house the further away I go. It went down until it disappeared from me when I went further north above North Carolina. It seems to radiate closely from a central point around the national Forest. Due to terrain I'm unable to physically find a central point. Flat musical notes cancel it. It appears to be a very low b flat only obtained electronically.

It's a low frequency pulsating droning/rumbling similar to the sound a heat/water pump (HVAC) or a diesel generator makes. I live about 800meters (half a mile) from the largest Navel base in…

Low pulsing hum like that of an idling engine or generator on the edge of perception. It seems to vibrate the ear drum at the tip of each pulse almost like the ear drum is spasming. I have a…

Low rumbling hum. Like machinery off in the distance. I can "feel-hear" it. So when you ask if it's in both ears, that's almost difficult to answer. It's just "there" ... kind of always hum-…
