Don't drive your car! If by 'loud' you mean there's knocks and rumbles - that sounds like serious damage caused by zero or low oil pressure. If there's no terminal damage yet caused by a lack of oil pressure .. there soon will be.
Don't drive your car. Get somebody qualified to have a look at it first. Your oil pressure warning light is on because there's no oil pressure. You're liable to destroy the engine (very quickly) if you run it with no oil pressure.
The first thing you should do is check your engine oil level. Make sure that the oil level reaches 'full' on the dipstick.
If your oil level has been unacceptably low - top up and start the engine. The oil warning light should go out within a couple of seconds. If not - it points at a problem elsewhere. Don't run your engine with the oil light on. Get a second opinion.
