A low hum in Sweden, Filipstad Dammhyttan 2 (www.hitta.se)
Low frequency noise appearing indoors when other sounds are masked It starts sometimes in the middle of the night. Freezer trailers parking in numbers at an industrial area ON TOP of a small hill is a plausible source, also a huge bioenergy-plant. Stupid planning. Sweden nowadays. Not like it used to be.

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.
