Abstract
PURPOSE: To increase the vibration-proof property of soundproof type electric appliance, by fitting material, such as concrete, having a large attenuation constant to the neighborhood of the joints of supporting members consituting the framework of a soundproof wall.
CONSTITUTION: Concrete 9 is fitted to each joint of supporting member 2, supporting racks 4A, 4B, 8A, 8B in a fixed length. The length l of the concrete to be attached is set at 1/10W1/4 of the length L from a joint to another. Since the vibration of attachments 5A, 5B to be placed in the upper part of the soundproof wall poses a problem, supporting member 2, which constitutes the framework of the soundproof wall is invariably fitted with concrete 9. Since supporting racks 4A, 4B are by far smaller than the soundproof wall, it may be sufficient merely to increases the toughness of the constituent members.
