Abstract
In a sound insulating device, a long sound insulating member including a polyhedron body bent at a predetermined angle to open a sound source side is sequentially stacked between supporting columns arranged in an upstanding manner at a predetermined spacing to configure a sound insulating wall 10 having an appropriate height. Sound waves from a sound source interfere with each other due to the polyhedron body to reduce noise.
Claims8
A sound insulating device comprising:
- elongated sound insulating members each including a polyhedron body bent at a predetermined angle to open a sound source side, said sound insulating members being sequentially stacked between supporting columns arranged in an upstanding manner at a predetermined spacing to configure a sound insulating wall having an appropriate height, said sound insulating members being configured such that sound waves from the sound source interfere with each other due to the polyhedron body so as to reduce noise, wherein one end side of each of the sound insulating members is bent to an opening side on a side opposite to a bending direction of the bent portion to form a bending portion;
- and
- an elastic member fitted between each of the sound insulating members and the respective overlapping bending portion.
