A few months ago it started. Think of an industrial fan sound 24 hours a day.
When it began I thought it was a temporary thing - maybe a broken air con on an adjoining building, or some fan going on nearby building works. Its been six months now, non stop. Whirrrrrrrrrr - never varies or pauses.
We are in flats and I just can't pinpoint the source when I get to street level. It just wasn't there before - I had some recordings which I made last summer of me reading lecture notes (so I could play them when commuting) and all you can hear in the background is the little birdies tweeting.
It's so hot now but if the windows are open it sounds like I'm sitting in a bus station. I can hear of over the TV with my windows closed.
Can environmental health help? Which sodding engineer/architect/builder decided that something that noisy is OK in a residential area?
I am getting really hacked off! Make it stop!
