Abstract
Systems and methods for acoustic feedback or resonance mitigation are provided. The systems and methods include an exhaust acoustic noise reduction apparatus having an exhaust port comprising an exhaust aperture, a first vane extending at least partially across the exhaust aperture, and a second vane extending at least partially across the exhaust aperture and intersecting the first vane, such that the first and second vanes are oriented to interfere with formation of an acoustic feedback loop and reduce an acoustic noise signature of the exhaust port.
