HMO house noise situation next door has reduced to a reasonable level now.  But this has nothing to do with Stevenage Borough Council; because as far as they are concerned, I can stay here and rot instead of them solving the noise situation!  The level of noise now, is what I suppose is known as 'living noise' - unlike what the council had classified as 'living noises' before from their covered-up and flawed noise investigation.

The noise changed from the HMO property was achieved where it seems one of the young male tenants that was creating most of the noise was kicked out for non-payment of rent, and been replaced with 2 couples - one couple and a child, and the other couple with a baby due soon.

I don't suppose all the noises can be got rid of because of the poor construction of these domestic houses, moreover, being fitted with 6+ hydraulic spring fire doors that they weren't designed and built for.
