Question: motor loud??

I have a 2008 Chevy Cobalt. Recently I went over a huge bump... Now, my motor sounds revved, loud and vibrates when I turn the car on. It also sound revved or loud when I accelerate. But, when I am drive for a while or accelerate to a fast speed and slow down, I don't hear the noise anymore. For example, I got onto the straightway and when up to 50 mph. After I came off, and started driving 25 mph, I didn't here it any longer. The weird thing is, you can not hear the noise outside the car, just inside.
