Best material to use to replace floorboard?

Many thanks @JobAndKnock. That top advice.

Why not lift the boards again, put in sound insulation, then put boards down and ply over the top with a good carpet with good underlay. No new timber needed, and probably better result for sound proofing?

I'm always a bit leery of recommending this - for starters we don't really know how old the house is. In old houses (e.g. Victorian or Edwardian, so 100+ years old) lifting original floor boards is often a fraught job as old pitch pine floor boards can be so brittle with age and wear that you run the risk of wreckingh 50% or more of them. That makes for an expensive repair solution where it often ends up being better to scrap the lot, level the joists and put in a brand new plywood or P5 chipboard sub-floor (at least in labour costs).
