Well, heat shields would most often rattle at a certain rpm, often at idle or just above. An rpm related noise might indicate a pulley bearing or waterpump issue. I would pull off the access panel in the cabin and listen with a piece of plastic tubing or some such to isolate the source. Also bang around underneath with a rubber mallet so see if it’s not part of your exhaust system. Etc.
