It sounds like it is coming from the rear tire area. There doesn't seem to be any uneven wear on the tires and it doesn't affect handling or driveablity. It's like a low whumping sound that gets faster paced the faster I drive until it's like a steady low hum on the highway. What could it be?

You can determine if its a tire related problem by having the tires rotated (front to rear) and, if necessary, cross-rotated (in an X pattern) to see if the noise changes or moves with the tires. Often times a slight cupping in the tires will be elimiated by moving a rear tire that is cupped to the front where the weight of the engine causes the tire to deflect and eliminate the noise.
if the noise doesn't move when the tires are rotated, the probability is that you have a bad wheel bearing at whichever side your hearing the noise from. There are a few other possibilities before condemning the wheel bearing.
Another thing that causes the type of noise you have is not tire related. That type of noise can be caused by driving with one window partially open. For example, if you have the driver's window open about 2" and the other windows shut, you actually will get a 'thumping' noise as the pressure differences between the air going over the car and the air inside the car cause the air fronts to collide. If you drive with the one window open, open the window on the other door and see if it eliminates the noise as you will equalize the pressure by opening another window.
Most cars have pressure vents in the rear body behind the rear wheels and they could be the source of the noise as well. These vents are basically plastic doors at the back of the car under the bumper sides that allow the pressure waves that are created when you shut the door to exit the car through the vents. you may want to turn the interior fan blower motor 'HIGH" when you hear the noise to see if this changes the noise. Using the blower motor will pressurize the interior and should open the vents to release the pressure. If the noise is still there then the vents are working and its something else.
in order of probability, its usually a cupped tire followed by a bad wheel bearing provided you're not driving with only one window open.
I recommend you take it to a honda dealer and ask to have a technician road test the vehicle with you. most dealers won't charge to have someone do this. then at least you'll have a professional opinion of what the cause is.
hope that helps

sometimes the tires have a defect in them. Basically, there can be an odd concentration of rubber, or some internal part of the steel belt has come apart. I can't say for sure, but I ahve had that sound come from a tire of mine. It was replaced under warranty after about 10k miles.
