Noise level in the running Elevator cage is divided with the element that originates in cage mechanical vibration and that generated by running. The later called Aerodynamic noise. This Aerodynamic noise increases rapidly by the elevator's running speed and generate close by the cage surface. We measured Aerodynamic noise and inner cage noise levels, and confirmed that the noise levels are proportional to from 5th to 6th power at the cage running speed. Next, we calculate computer simulation about running Elevator cage, and compared analytical results with the experiment results. Analytical results have the possibility that the generated Aerodynamic noise can be forecast.
