I didn't really understand what you are saying, but I guess you have a noise when the car is in gear. Does the noise happen whilst the car is stationary any in gear or moving. If stationary, does pressing the clutch stop the noise? This could relate to transmission problem! Does the noise increase with the engine speed or road speed.
Possible causes. If moving and under load, then the engine could be shifting enough to cause exhaust or inlet parts to leak. An engine mount has broken causing a moving part to touch.
Clutch or gearbox has a problem.
A foreign object lodge in brake area, wheel bearing, loose wheel nuts!
You need to give a more detailed description of when/how the noise has occurs, using my pointers, to roughly get an idea of possible causes. It's hard not being there in person to give a better diagnosis. You may need to find a friendly garage or person with a bit of knowledge locally to help you.
