Recently in Japan there has been an upsurge in the construction rush of multistoried buildings due to the concentration of population in big cities, especially in the Tokyo metropolitan area. This has been exacerbated by the tremendous increase of land prices. This has accelerated demand for elevators of a higher speed and better performance. To meet this demand, many technical problems which did not exist with the traditional type of elevators must be solved. One of these problems is aerodynamic sound. This paper introduces fundamental experiments and numerical simulations for suppression of aerodynamic noise around the elevator car generated by air flow and improved sound isolation inside it.
