A hum with constant pitch. The overall volume may differ from day to day or hour to hour. But otherwise the volume is usually constant. Sometimes it stops for a second at irregular intervals and than instantly resumes at the same volume. The hum is not affected by earplugs. However there is one thing that absolutely stops the hum: When I softly touch and rub the little hairs on my right ear (producing a little sandpapery sound) the hum stops completely. However this has absolutely no effect when I do it on my left ear. The two locations where I hear the hum most prominently (my home and my mother's home) happen to be approximately the same distance away from a highway and a highway bridge.
What they reported
First noticed: 2009
Pitch: 59 Hz
Loudest: During the night
Where: Indoors
Symptoms: Sense of vibration
Changes with weather: For a time a was certain it changes with the wind direction and temperature. I did not investigate it, though. I deduced it by the sound of the cars on the nearby highway. When I could hear the cars loud and clearly the hum seemed to be most intense.
What stood out: a low hum

First I thought of a running washing machine. A Diesel engine or distant road construction is close too. Furthermore there is a fast bubbling sound like Geiger counter or the bubbling of a a…

It sounds like a cello or bass instrument continuously playing only one note in the lowest octave no higher than g1 sharp. The hum plays both staccato and whole notes, and it strongly resemb…

Write it down while you still remember the details. We will look for the others.
Tell us what you sawIf this reminds you of something a friend or a relative told you once and never mentioned again, send them this page. Reading that a stranger described the same thing is usually the part that helps.
