Central Park musicians say they’re being drowned out by a noisy propane generator hooked up to a new food truck at the iconic Bethesda Fountain Terrace.

The Fatty Snacks food truck is in a “quiet zone,” where open-air performers are routinely ticketed by city Parks cops for being too loud.

“The generator makes more noise than the musicians,” complains vocalist John Boyd, 48, who has been smacked with five summonses by cops.
