    Noise transmission from floors can sometimes be problematic, but usually when Proprietors change from what was originally in place when the Building was constructed; like from carpets to a floating floor.

    Your problem is somewhat unusual in that due to the age of your Building the original floor was timber, and from what you're saying none of the previous Owners has never had it carpeted and then taken it up (?).  

    I'd check that with your Owners Corporation (O/C) though, because the applicable Model By-Laws that your Plan would have most likely adopted state that Proprietors must notify (read: seek the consent of) the O/C before changing any floor covering to one that may create noise (By-Law 14), and that the floors of a Lot (Unit) must be covered to the extent that there's no noise transmitted to other Lots (By-Law 15); bathrooms, kitchens, and laundry areas excepted.

    Depending upon what's occurred over the 80 years, it's likely that you will have to cover or otherwise treat the floorboards “to an extent sufficient to prevent the transmission from the floor space of noise likely to disturb the peaceful enjoyment of the owner or occupier of another lot” (By-Law 15). That doesn't mean carpets though, as some selectively placed furnishings and scatter rug/s or carpet runners can work wonders!
