You'll get used to it...
On offshore deliveries, I'm always amazed at how well I sleep once past the first few (loud) days at sea. Like a baby; maybe even more soundly. BTW, the best way to gently but successfully wake someone up for their watch is to gently pull on their pillow.
On land, I'm always surprised, in the spring when we start sleeping with the windows open after having them closed all winter, at how loud our neighborhood is -- trucks emptying dumpsters, cars on the cobblestone street, train horns at grade-level crossings, tugboats at the lock down the river, the neighbor's squeaky garage door. Then we're used to it and sleep right through it after about 3-4 days.
