can you provide more info? where the sound "seems" to be originating from, any difference in driving characteristics other than noise, idle, etc?

Have you recently purchased new tires? Depending on the tire design, some tires can cause an annoying "hum" as your speed increases.

ya know im having a similar sound. tonight when i swap out my 18's for stock wheels im gonna check the suspension and see if something is just resinating at idle in the car. cause the car is definately making more noise than normal. also might be my cracked air damp under the engine bay, it cracked a few weeks back.

just see if you can get a diagnostic or call a mechanic. They'll usually tell you what the problem might be for free without working on the car.
