How Loud Is A Helicopter Db. Jet flyover at 1000 feet (103 db); The amount of noise depends on the size of the propellers and the velocity of the propeller tips through the. A vortex is created to even out the air pressure, which produces sound vibrations when it hits the next blade. The air pressure decreases above and increases below the blades as the main rotor spins, providing upward thrust. Propeller aircraft and helicopters can also create noise from their rotating propellers cutting through the air. to make things more complicated, an increase of 1 db is just barely noticeable by human ear (or brain). 3 db is perceived as. · jet plane or helicopter; · large scale sporting events; · rock concert or symphony orchestra; loudness, measured in decibels (db), is the most commonly used characteristic to describe noise. jet aircraft noise is caused by high velocity exhaust gases mixing with ambient air, combustion of fuel and compressor fans.
