A low hum in 91026, 56100
It is a low frequency noise, it isn't continuous and it is irregulary. It is a noise as a water pump in action producing vibration. I can't hear it every day, but the strange thing is that I can hear this in three different places, like Pisa, Turin and Mazara del Vallo, all of them located in Italy. The sound is the same in each city. The same intensity, frequency and irregularity.

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.
