History Repeating

So fairly recently I had a problem with a neighbour which led me to moving shortly after moving to Bridgnorth. Currently I live in a 3-storey block of flats, with one flat on each floor. For the longest time it has just been me in the top flat, this guy in the bottom flat and the middle flat has been unoccupied and up for sale.
Well, eventually the flat got sold and people moved in. Now, when I was looking at this place I met the previous tenant and I asked specifically can you hear the people below you? To which she replied no. Based on that I put in the application and the rest is history, here I am.
Now that people have moved in to the middle flat I can indeed hear them. Slamming of doors, footfalls, even voices which is technically worse than where I was with the terrible neighbour. Luckily (for now) there's been no banging on their ceiling complaining of noise but the feeling is that if I can hear their noise, then they can hear mine, but if I've got that in the back of my head, I will (and already am) start censoring myself - which I really hate to have to do. When I got home, I close the door on the world and then I'm free to do whatever.

It all feels like a bit of history repeating but maybe that's just how flats are. Here's an idea how about they make the floors/ceilings a little thicker? I mean, I can undestand the problem at where I was before - it was a house that was converted into 2 flats but where I am now is a purpose built block of flats.
Here's hoping that my next place won't suffer from this. Or alternatively I find a house for rent like the one I lived in at Kidderminster - no noise problems there...
