carosio   178 #127 Posted October 7, 2015 If it can be established that the frequency is 50hz or more likely its second harmonic at 100hz then it almost certainly originates from the mains supply network. Tracing the source wouldn't be easy as these frequencies tend to be (as mentioned before) omni-directional.  You are probably familiar with the hum given off from small transformers, this is due to the mains frequency vibrating the core at 50/100hz.  Possible sources are substations, pylons/power lines, smaller substations for factories/shops, or even the underground power cable network.

It was intermittent, every 30 minutes it was constant and then stopped for 30 mins (just as I drifted back off!!!) Very annoying. It was so loud outside but from bed it sounded like someone a few doors away had a hairdryer going. Share this post Link to post Share on other sites Share this content via...
Rivelin6 Â Â 11 #129 Posted October 7, 2015 If you live anywhere near Holme Lane I had this problem a few years ago and it turned out to be that factory next to Supertram terminus. Environmental Health came out and the factory swore they turned machinery fan off at night time and weekends but they often didn't. Environmental Health made them put a box round it but it didn't improve the hum much:( Share this post Link to post Share on other sites Share this content via...
Mikes-joiner   10 #130 Posted October 7, 2015 Well yes it's Hillsborough but I've never heard this in 2 years of living here!  Its probably the electricity sub station behind Bassets or the pylon, these tend to hum when the air is damp.
