Problems solved by technology

However, the advancing direction of the noise forms almost a right angle with the extension line of the inner space 14a defined by the inner wall 14, and thus it is difficult to sufficiently generate destructive interference of the noise
Therefore, it is difficult to obtain a significant noise reduction effect through destructive interference of noise

Embodiment Construction

[0039] Mode of the invention

[0040] In the following, see Figure 3 to Figure 9 A noise reduction device according to an embodiment of the present invention will be described.

[0041] The noise reducing device 100 of the present embodiment includes: a spiral member 110 including a spiral portion 111 having a shape of a spiral plate; two side shielding members 140 shielding two open sides of the spiral member 110; And the central part 150 , which is arranged in the spiral part 110 and attaches the two side shield parts 140 to the spiral part 110 . The spiral part 110 may further include a flat part 112 as necessary, and the noise reduction device 100 may further include a front filter part 130 , a sound absorbing material 120 and a common part 170 . Hereinafter, a noise reduction device including the above elements will be described.

[0042] The helical portion 111 in the helical member 110 of the noise reducing device 100 is a plate-like member having a helical cross-se...

Abstract

The conventional noise reducing apparatus has a low noise reducing effect, and it requires a lot of time to mount the noise reducing apparatus on a soundproofing wall which in turn incurs high costs. The present invention provides a noise reducing apparatus including: a spiral member including a plate-shaped spiral portion having a spiral cross-section; two side shielding members for shielding the opened lateral sides of the spiral member; and a central member disposed in the spiral member and holding the two side shielding members tight to the spiral member, in order to improve an easiness of the installation and the noise reducing effect.

Description

technical field [0001] The present invention relates to a device for reducing noise, and more precisely to a device for reducing noise mounted on a soundproof wall installed on both sides of a road. Background technique [0002] When the noise generated from the road is transmitted to adjacent buildings such as apartments, it causes a lot of inconvenience to people living in the apartments. In order to solve the noise problem, soundproof walls are usually installed on the road boundary. The soundproof wall includes a plurality of columns arranged at constant intervals on the road, and soundproof panels coupled between the columns. Furthermore, a sound absorbing material may be provided in the sound insulation panel. However, although the conventional soundproof wall can block the noise transmitted to the lower floors of the apartment to some extent, it cannot sufficiently block the noise transmitted to the upper floors. In order to block the noise transmitted to the upper...
