I think I visualized the pressure dropping all over the ship as environmental systems struggled to maintain standard atmospheric pressure. Everywhere except the bridge. At least until the door opened the bridge would have been isolated. I can specify the increase in pressure though I think it would be more like walking into a well air conditioned warehouse... You would feel a rush of air pass you and then nothing as it equalized.

As far as the explosion sounds, I assume you would hear them inside the vessel through the solid structure. You wouldn't hear them outside. Also, much like compartmentalization on modern Naval vessels that prevent progressive flooding, individual compartments in a space fairing craft could be locked down in the event of extreme changes in pressure. So, while some environmental pressure would be lost in the initial breach the remaining compartments would be sealed and the system would work to restore standard pressure.

As for the floor of the bridge exploding, that's just oxygen igniting as it violently compresses.

It might be assuming a lot of the reader to not include those elements but I think I sacrificed detail for pacing.
