I reckon probably not.
The sound of steps will be transmitting through the solid materials that link your flat to the stairs which is likely going to include not just your wall but the ceiling and floor too. To get a substantial reduction you’d therefore need to float not just a new wall but potentially a new floor and ceiling.
I do kinda like the idea of dynamat and plasterboard, the different materials ought to baffle a good range of frequencies but as it sounds like you know for a significant reduction you’d need a new solid wall fully isolated from the existing solid wall with air between.
Maybe carpet the stairs in the dead of night.
Hefty-

You joke, but I’d be seriously considering guerrilla / gorilla gluing some rubber treads onto the stairs. Safer for everyone, quieter for you. Also a cheap experiment, and it’s not like you’d actually get in trouble for it. If I lived in the block I’d just assume the maintenance people had been told to comply with some new reg.

Got a flat in a 1940s concrete and brick block which I'm totally renovating. Since moving I've realised that I get noise through the walls that face the common stair place. Main problem area is the kitchen, but there's definitely flanking because the ceilings and other walls are also brick and concrete. The ideal (but unobtainable solution would be for the stairs to be properly lined because it's noise from hard shoes that reverberates, not talking or other airborne noise. Can't afford (money or space) to do a full job of a suspended wall with loads of gap, sound insulation etc. Kitchen units will go against the wall which might help a bit, but wondering if it's worth me losing 20mm of space to line with a heavy vinyl mat and then green glue on some 12.5mm acoustics plasterboard. Anyone tried that? Good money after bad or worth a punt because it might at least soften the clank of heavyset people in stilettos coming down the stairs?! Any advice appreciated!!
