Different people use different terminology to describe what they hear. To some folk a noise might be a thumping wile to others it could be a banging, a knocking or something else.
To have a chance of giving you a clue where to look the description must be a picture painted with words - accurate and comprehensive, which is almost impossible for those unused to describing things...
Unidentified noises should be assumed to be potentially dangerous and/or expensive until discovered otherwise and so it is important the car is taken quickly to someone experienced in interpreting and locating noises. One typical thumpthumpthump noise that increases with road speed rather than engine speed is a deformed tyre.
It could be the timing belt or chain depending on model engine fitted. if its not coming from the engine it can be a drive shaft check these by pulling on them and any abnormal movement the universal joint may need replacing.
