Topic: continuous low-level noise
For the last few days there has been a low humming noise coming through the wall from my neighbours' (terrace) house.
It is as if they are running a pump or fan or suchlike around the clock.
It is not very loud, but I do find it oppressive when I am trying to get to sleep at night.
I am afraid that they no longer speak to me since a dispute concerning the back garden fence some years ago.
I have no idea what is causing the noise and it may only be temporary, but what if it is to be a permanent feature? As I said, it is not loud, but it is upsetting - I am writing this at 5am having been unable to get to sleep).
