When do you hear the noise? Is it all the time or when you have a load on the engine?

It started a couple of months ago but it wasnt that loud of a knock and it just got louder and louder. Yea its all the time but when I let it idle its not that loud but when I hit the throtle just a little bit its real loud idk what it could be!
