hey man if it's in your rear then it could possibly be the wheel bearings but they'd have to be really worn out. also another very common thing to go out on honda/acura rear ends is the trailing arm bushings and they can cause noise too. if you wanna check if ur bearings have play then just jack the rear of your car up and slightly wiggle the wheel from top to bottom and side to side as if you were trying to twist the wheel off. if you have any play at all the bearing is bad. if not then look towards the bushings.
