I couldn't imagine a boom knocking down walls.
The exothermic front from a detonation is supersonic, and would probably be considered a 'sonic boom'.

Based on some internet comments the wall in question is on a VERY old building.
If a window could be broken, an old, un-reinforced brick wall with nothing behind it (and possibly poorly constructed) could be knocked down.
