Anomalylike a low bass noise- like a bass from a car but a few streets away I spoke to the council who said they hadn't had any reports of anything similar. I then went to see a specialist (who scanned me using an MRI) for a possible brain tumour but this came back negative. This is a huge problem and I feel has affected my sleep for years now.
