That's gotta be the SunTour Pro Compe freewheel. Two big pawls and strong pawl springs. Having a noisy freewheel can be comforting in some ways. I like mine quiet.
If you want a louder freewheel just remove the wheel and dribble a solvent through the cracks in the freewheel housing. This should remove the light grease inside the hub making the pawls louder.
Is this good for the freewheel?
Ha....
