Two mysterious noises have become apparent in the last few months. Both are virtually imperceptable in the daytime, but at night, in my quiet street, I can hear them from my bedroom.
First there was the humming. It started sometime last year. It doesn’t seem to be in the house anywhere – I tried turning off all the power one night at the fuse box, and I could still hear it. No, it’s not coming from the Smart Meter. It might be some way off but resonating with something nearby, as often I can merely tilt my head slightly and I can no longer hear it.
More recently a kind of “gloop” sound has started from somewhere on the bathroom-side of my bedroom. I assume it’s the drains doing something weird, as when it first started occurring, I checked and double checked there were no leaking taps.
Happily neither of these keep me awake at night. But I’m intrigued.
