Narrative:

Passing 18;000 ft during climb; we noticed a 'thud' and our ears popped. We immediately directed our attention to the pressurization; and all looked normal. Within a minute; the flight attendant called and asked what the noise was and that there was a sound of rushing air in the cabin. We then noticed a strong burning odor and decided to divert to ZZZ which was 15 minutes away. The odor lasted for about 2-3 minutes. There was a slight amount of smoke that could momentarily be seen coming out of the side vents; but it didn't last more than 30 seconds. We ran the QRH; notified dispatch; and landed without incident. On the descent; we recognized that the cockpit had gotten warm; leading us to believe there was an issue with pack 1 (as pack 2 had been MEL'd at the gate prior to pushback).
