One hour resistive construction refers to the fire rating, not the sound proofing of a wall. Common walls in condos, apartments, duplexes, and any building where there is more than one residence require fire resistive construction. Usually this requirement is satisfied by using 5/8" Type X drywall on each side of the wall, from the ground all the way to the roof. It has to be Type X drywall because the material in the core is different than regular drywall.
Sometimes architects specify two layers of Type X drywall on each side for extra fire resistance.
In better construction, sound proofing of common walls is enhanced by staggering 2x4 studs on 8" centers in a six inch thick wall, with insulation between the studs. That way, each side of the wall has its own set of studs that are 2" away from the other side of the wall, preventing sound from being transmitted through the studs.

One hour resistive construction has no meaning in terms of soundproofing, rather it is a rating of how long it can contain a fire in the neighboring condo before it will spread. A one hour resistive wall will transmit sound just like any other wall if it is not sound proofed.

One hour construction refers to the ability to keep fire and smoke isolated in one area. 5/8" sheetrock on each side of 2 x 4 studs meets this requirment in most localities but you should check with your local building code official.

That means it is a material that will hold back flames for one hour.
