Hello, I'm sad to say that noises are a really difficult thing to distinguish in this forum. Very few occasions occur where a noise is common enough to be guessed at. This isn't one of those occasions. You'll need to see a local shop near you to have this listened to and looked at. A good shop and good techs will be able to give you a swift answer.
