    For 2 years now Windsor has been experiencing a 'hum', as in one of those low, disembodied vibratory sounds that this site has had so much fun debunking. There's suspicion an American steel-mill on Zug Island is the source, http://www.theglobeandmail.com/news...-study-mysterious-windsor-hum/article7619273/

    But of course those who espouse the global 'hum' conspiracy are loving it.
    I live in a major steel-city, and we don't have any 'hum', so I wonder what they're doing in those factories, if it is the factories, to make such a damn racket. Must be hell to work there day after day if it is the source.
    Don't believe myself its anything but some messed up industrial process, but I figured y'all might be interested.

    Have you ever seen what goes on in a steel mill or a forge?? "Damn racket" doesnt' even begin to describe it!

    It was working in such a place that inspired Black Sabbath to make 'heavy metal' music.

    My home town, Bristol in the Uk has had a 'hum' for years...

    http://www.bristolpost.co.uk/HUM-KNOW/story-20347005-detail/story.html

    The above site, our local news rag, will not allow me to copy and quote, but the following, which blames the hum on causing cancer and driving people to suicide, gives a rough over view of the story...

    (The bold is from the original source)

    I've been living in the city since 1981, and can honestly say I've never heard it, but there again having spent most of my life in very loud rock bands my hearing isn't exactly 100%. However I have several friends, who are perfectly sane and upstanding people, including an aeronautical engineer and a teacher who swear they can hear it fairly regularly.

    It has variously been attributed to heavy machinery, traffic on the M4, M5 and M32 motorways that pass through or near the city, engines of ships in Bristol channel, passing trains, high voltage power lines, tinnitus, or even a psychosomatic effect and mass hysteria.

    I live near a platform where tankers offload oil. It is about 1 mile from my house to the shore, then the platform is 1 mile offshore. I can (rarely) hear engines from the ships. When I hear it, it sounds just like these people describe. It is one in hundreds of ships that makes this hum. I would think if it has been bothering these folks for so long someone could find it. Although I do "get" what the mayor of the town said, he can't hear it. In my search for the source, I would totally lose the sound, then pick it up again.

    This is possibly due to what is known as a standing wave. Say you are in a rectangular room. there will be one or two frequencies whose wavelengths fit EXACTLY into the space of the room. This then means if this particular sound frequency is in the room, in some places, you can't hear it at all and in other places it will be really loud. This is why recoprding studios have sound deadening and angles all over the place, to remove standing waves where possible. There could easily be something similar between the ship and the wall of your house for example.

    I can remember sitting outside the Tesco store in Henley-On-Thames in the UK and the hum was deafening. I noticed there was a hill directly opposite and a train track that ran between the store and it and I was thinking maybe an electrical origin or some such phenomena. Maybe there were phone masts nearby that might have caused the hum and interacting with the local geography in some ways. The hum was unmistakable on some nights and completely missing on others. It was like being in the presence of a billion cicadas :D

    I just stumbled upon this video that talks about hums, The Bristol Hum in particular

    It doesn't reach any conclusions but does explore a number of possible causes including external environmental sources such traffic and industrial noise, natural sources such as wave action on sea floors, internal biological sources such as blood flow through the inner ear and military sources such as VLF radio signals. Its only 12 minutes long and is an interesting watch.
