All well and good, I'll just relay my experience. B2B cruises - first leg deck 10 room, second cruise deck 9 room.
On deck 10 we were located underneath the entry area to Cabanas on the starboard side. Really not much noise to speak of. Daytime, could hear kid's (people) walking/running occasionally, and Pirate night we could hear the bass on the music being played for the party on deck.
On deck 9 we were located more midship on the port side. The noise in that room was quite intense. Issues - on one side of us we had two connecting rooms with kids (I hope it was kids) who liked to take laps through the open verandah door and interior connecting door, accompanied with the shrieks that kids do when racing each other. Other side of us 3 connecting rooms with someone who really liked jumping off the bunk bed (a lot). All that added to the group of people on deck 10 who felt the only way to get from one end of the passageway to the other was to run foot races (day or night).
You just can't tell.
