I live in Doncaster between the M18 and Robin Hood airport, this for me has become a regular occurrence being woken up by the noise between the hours
of 4am an 6am. Usually its seems a very low frequency sound also at the edge of my perception. But last night it started off the same, maybe lasting 3
minutes a rolling alternating vibrant sound that fades and comes back, it eventually suddenly stops mid way through a loud part which I always found
interesting, you then hear the background noise of vehicles traveling the motorway in the distance.
The usual obligatory couple of minutes wait for it coming back but nothing so go to the kitchen to get some water, I hear nothing until I get back up
stairs then it starts again.
The same low frequency pattern starting perceptively low then amplifying but this time very loud ! it seem to emanate from every direction with the
same peculiar rolling pattern. I changed rooms, opened windows but couldn't identify the direction. It was about 4:30 am dark with low cloud cover no
discernible lights. Weather was calm with no wind or rain, very light traffic and definitely no flights, a car drove down my street as the sound
continued.
I have lived here many years and I know the difference between the distant motorway road noise or planes taking off and landing when the cloud cover
is low.
I know the difference between the sound of turbo prop an jet, in the past weeks I have tried to rationalise the sound from everything electrical in my
house to noise the wind would make to distant vehicle noise .. nothing fits.
and to make it even stranger the noise last night when at its peak amplitude was such, it seem to be propagating from only inches away from my head no
matter which way I faced it seemed to resonate inside my head like the way large mortar fireworks thump inside your chest when they go off.
All this time I've never thought to try and record it but next time i will be ready
