As part of this ickle problem with the flat. Thinking about getting someone in to properly advise. The initial stage of which is to try and have a conversation about what the problem is, likely solutions etc.
So, anyone actually know someone who knows about acoustics and domestic spaces?
I can imagine varied potential solutions. Cavity walls maybe, are there types of double glazing with vacuum in them? Would that even help? How about trying to just deflect sound with a bit of perspex? There will be people out there who do this for a living. So, given the incredible knowledge space of you readers, anyone know anyone who does?
The basic problem, music source at 120 dB (possibly 130) at 20 metres distance. How do we get that down to just mild background internally? Without killing the DJ that is.
