I'm investigating noise from next door in my 1960s semidetached bungalow.

From external measurements, from the edge of my window, to the edge of my
neighbour's, is 103cm. Internally, there's 27.5cm from the edge of the
window, to the wallpaper on the party wall.

Assuming the same arrangements next door, there seem to be 48cm of wall and
plaster between my house and next door. And from inside the loft, the wall
appears to be built of breeze blocks.

Can a breeze-block wall really be that thick? (It would appear to need 4
courses of blocks.) Or is there likely to be a gap (of some 20cm?)?

At the minute the wall might as well not be there...

What's the simplest DIY solution to largely drown out the sound of two dogs
barking next door? (Apart from wearing earplugs, moving house, or, my
preference at the moment, machine-gunning both dogs)

Thanks,

This is a common bungalow problem. You will find the sound is coming
"over" the party wall in the roof space I f you get up in the loft
you will find there is a rafter running down close to the party wall
but not actually touching. the sound comes in here and thence throught
the ceilings.
So, get a can of foam and fill this crack up, making sure you shove
the pipe up as far as you can. Trim off and then put on a cement
fillet.
You can only use this foam in warmish weather BTW. Screwfix is the
cheapest place I know for foam. Also put down more roof insulation,
the rigid board is more sound proof.
The slightest little hole lets in lots of noise so do a good job.
