Hello from London (UK)-Acoustics Forum-Acoustic Fields Forum

Hi folks,
my name is Primiano. I am sw engineer based in London UK.

I have a quite challenging situation. I’m in the process of buying my first flat. ).
I spend most of my free time on DIY and playing music. Through the years I made my own soundcard, my own amps and speakers.

The use case is a dual-usage living room + sound listening room . I’ll be playing mainly electric guitars (a couple of 2×12 cabs) and 6’7” grand piano. I am NOT going to do any recordings (i.e. outside noise sources are not a problem). The main thing I am looking for is isolating myself from neighbours. I don’t want to be heard while I rehearse. Sound treatment is not a top priority for now (it will be once I sort out neighbour isolation)

I wrote some detailed writeup about my situation, with some 3d drawings, in this PDF:

In essence the situation is the following:
– I’d be keen to do some structural refurb and create a “nearly”-box-in-a-box solution, floating on springs or similar to decouple structural noise. First of all any advice / thoughts on this overall?

– Even if do so, I cannot fully enclose the box, because doing so would remove light to the rest of the flat. So the question is: if I leave a side of the box open, how much energy will escape by reflection on the side (compared to the front). Is that something that could be dealt with with some acoustic underlay on the original floor.

– How likely is that the reflected airborne noise will create flanking/ structural noise when hitting the other S-shaped drywall ?

Really appreciate any thoughts on this.
