I have just started hearing the hum since moving house a nmonth ago. Some nights I can sort of ignore it and others it drives me mad and keeps me awake. The other night I got up and turned the power off just to make sure it wasn't coming from inside my house. My boyfriend can't hear a thing. I am 37 and have good hearing. To me the description of a distant engine running is accurate but I seem to 'feel' the sound more than hear it, when it is bad it feels like the inside of my ears are vibrating, I likened it to the feeling you get when a helicopter is about to fly over, before you properly hear the rotor blades, or when a car or bus is idling and the vibration is uncomfortable. I cannot hear it at all anywhere away from my home, and usually only inside at night, though sometimes during the day in my garden. Someone mentioned gas pipes, there is a mainline near my road, might that make a difference? It is a real puzzle but I am so glad to see so many other people can hear it and I am not going mental! Is it worth getting a hearing test just to rule out tinnitus? Thanks, Debbie
