Most likely, air accumulation in the system. Purge radiant terminals with pump stopped, restart system and listen for noise. Repeat as necessary until noise stops.

Also check your boilers water pressure/altitude. When a boiler is short on the water pressure it will also cause the same problem and will not bleed correctly.
