Narrative:
While in cruise at FL370; the flight crew noticed the cabin altitude started to increase. A few seconds later; they noticed their ears starting to pop in relation to the changing cabin pressure accompanied with a whistling sound. The cabin altitude continued to increase and reached the point where the aural warning was alerted. The ca told the first officer to put on his oxygen mask and that we would be starting an emergency descent. The ca then informed the flight attendant of the situation and instructed her to put her mask on as well. The flight crew performed the rapid cabin depressurization and emergency descent checklists. The ca then informed the dispatcher of the situation via ACARS and notified him of the diversion. The crew performed a successful emergency landing and taxied the aircraft to the gate. The cause was due to the aircraft's pressurization system failure to maintain cabin pressure.
