The XF-84H was quite possibly the loudest aircraft ever built (rivaled only by the Russian Tupolev Tu-95"Bear" bomber[16]), earning the nickname "Thunderscreech" as well as the "Mighty Ear Banger".[17] On the ground "run ups", the prototypes could reportedly be heard 25 miles (40 km) away.[18]Unlike standard propellers that turn at subsonic speeds, the outer 24–30 inches (61–76 cm) of the blades on the XF-84H's propeller traveled faster than the speed of sound even at idle thrust, producing a continuous visible sonic boom that radiated laterally from the propellers for hundreds of yards. The shock wave was actually powerful enough to knock a man down; an unfortunate crew chief who was inside a nearby C-47 was severely incapacitated during a 30-minute ground run.[18] Coupled with the already considerable noise from the subsonic aspect of the propeller and the dual turbines, the aircraft was notorious for inducing severe nausea and headaches among ground crews.[11] In one report, a Republic engineer suffered a seizure after close range exposure to the shock waves emanating from a powered-up XF-84H.[19]
Conozco ese avion , esta en el museo de la Fuerza Aerea de EE.UU en Dayton , Ohio

Republic XF-84H
Was SO noisy, it made the pilots sick. 😂
+Mike LeTourneau really?

+Mike LeTourneau Thx. Damn loud
Hmmm. Supersonic prop weapon.
There were similar experiments with the B-47.
Dang…
white sands missile range in n.m.?
+Mike LeTourneau that most have been quite a show! Amazing…
No is not good
