A New wind-machine has been adopted and use for several years with a great improvement realized. It is a centrifugal blower, such as is commonly used in ventilating systems. The air is conducted by canvas ducts to the set where the scene is being enacted. The ducts are equipped with variously shaped fillings and nozzles so that the air stream may be directed as desired. — It has been found expedient to locate the blower outside the stage building and enter the duct through a special portal. Thereby the greatest noise source, the blower, is remotely located and insulated from the scene by the walls of the stage building. Furthermore, it incidentally serves as a ventilator, suppplying fresh air to the scene. Measurements of noise-level for various wind velocities indicate improvements up to 70 decibels in noise reduction. Thus sound recordings of scenes requiring wind are made possible where heretofore it was necessary to photograph the scene without sound and provide synchronized sound subsequently.
