AnomalyLow throbbing like a distant broken AC. It sounded like two low pitch waves very close together interfering. It seemed substantially louder in one specific place and moving my bed to a new location hugely helped my sleep. If it’s two waves interfering I think the wavelength of the interference pattern was about 5 meters, I think. The sound nearly ruined my life. I didn’t sleep for days at a time. I’m convinced that it was affecting my heart rate directly.
