This is a tough one as it’s a hospital building and the NHS have enough to deal with at present. Our garden backs directly onto the car park for a rehabilitation hospital and is generally really quiet . Three days ago the loudest buzzing noise started which is coming from a fan, I know as the same thing happened last year and the estates team finally gotten fixed after several emails etc .
The noise is so loud and irritating we can’t sit in the garden and my husband who is a Dr couldn’t sleep with the window open after a night shift .
I feel bad complaining but the only open space we have to use and relax has become practically unusable as the noise is grinding, it must be way above the acceptable noise decibels . What should I do ?
