Narrative:
As we were about to level off at FL310; aural cabin altitude warning horn sounded. The captain and I immediately donned our oxygen masks at 100% and established communications. I began a descent with the approval of ATC. I continued to fly the aircraft and communicate with ATC while the captain ran the QRH checklist. ATC gave us a vector for the descent and cleared us down to 14;000. The aural warning horn silenced shortly after our level off at 14;000. ATC directed us to continue the descent to 13;000. Per QRH guidance and input from company dispatch regarding the en route fuel requirements; we determined that we were able to continue our flight. Additionally; since we were able to regain and maintain control of the pressurization we elected to climb FL210 due to moderate turbulence at the 13;000. We landed uneventfully at our original destination.
