A low hum in Watford, United Kingdom
Low pitched hum like idling large diesel engine but very smooth. Can shift to a slightly higher pitch momentarily and I can conciously bring this about by a very slight body movement. It can be triggered by external sounds and/or movements but is distinct from them and often appears without any apparent trigger. I have a suspicion that there is an interplay between the source of the hum and the body's skeletal and tissue structure. Perhaps some type of resonance that involves bone density, rigidity and also involving the ears and the eyes, especially in persons over the age of thirty. (I was about thirty when this started)

Has this happened to you?
Write it down while you still remember the details. We will look for the others.
If 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.
Nothing is tracked back to you and nothing is sent on your behalf. The link is just the page you are reading.
