Name change as I've whinged about this in real life!
I live opposite a school. The block directly opposite me is windowless toilets so they require mechanical ventilation. The ventilation makes a humming noise like a constant tumble dryer.
It first happened a couple of years ago. I complained to the school, but it was school hols so I complained to the council. When the term started the ventilation was turned off.
A few months later it started up again so I went over to speak to the school. The facilities person apologised and went to turn it off. Peace!
Recently it started up again but just from 6pm to 8pm. Fine, a 2 hour window wasn't too bad.
However it's started up again from 6am to 6pm. It's the first thing I hear in the morning. I have to have a fan on at home to mask it. I got in touch with the school and they said they need it on or the toilets smell. They said their contractor says the noise is normal but they plan to replace the fan and clean it, and this might help reduce the noise.
My problem is I'm very sensitive to noise. I can't have ticking clocks, unexplained hums etc give me the rage. It's misophonia. So it could well be that the venitlation isn't a formal nuisance it's just me being sensitive. Visitors don't notice it until I point it out to them.
What should I do? Its making me stressed. I can't afford to move house and walking around with noise cancelling earplugs 12 hours a day is a crap way to live.
