A vortex is created to even out the air pressure, which produces sound vibrations when it hits the next blade. Jet flyover at 1000 feet (103 db); · large scale sporting events; The air pressure decreases above and increases below the blades as the main rotor spins, providing upward thrust. The amount of noise depends on the size of the propellers and the velocity of the propeller tips through the. jet aircraft noise is caused by high velocity exhaust gases mixing with ambient air, combustion of fuel and compressor fans. Propeller aircraft and helicopters can also create noise from their rotating propellers cutting through the air.
