ground loop noise
Redesign the board?
Lots of groundplane, dont have breaks in it, dont have breaks in the return path of noisy/sensitive signals.
Keep sensitive signals away from noisy ones, find out whats generating the noise in the first place & redo that section of board (if not all of it).

Re: ground loop noise
have atleast one solid plane to reference the signals.
keep it closer to pwr plane(if it were gnd)
add decaps wherever u think noise would appear...(this is just a brute force method actually u ll have to calculate the decap vaule and decide the placement after many simulation iterations)

ground loop noise
Filter, CAP, one point center grounding, shielding, etc.
