Document Type and Number:
WIPO Patent Application WO/2007/125577
Kind Code:
A1
Abstract:
A sound shielding device having excellent sound shielding characteristics.
The device can maintain the shielding characteristics for a long period, has
excellent assemblability, and can be disposed of easily. In the sound shielding
device, long sound shielding members (11) each have a polyhedron (12) bent at
predetermined angles and opened on the sound source side, and a sound shielding
wall (10) having an appropriate height is constructed by sequentially laying
over each other the shielding members (11) between supports (30) erected at predetermined
intervals. Sound waves entered from the sound source in the device are allowed
to interfere with each other by polyhedrons (12), and as a result, noise is reduced.
