Problems solved by technology

The traditional sound barrier works in a relatively simple way: one is guided by sound absorption, that is, the interior is filled with polymer porous sound-absorbing materials to absorb sound energy; the other is guided by sound insulation, that is, the use of metal, brick walls, etc. Thick and dense non-porous material to weaken the transmitted sound energy and block the transmission of sound

Embodiment Construction

[0024] In order to make the technical solutions and advantages of the present invention clearer, the present invention will be described in detail below in conjunction with the accompanying drawings and specific embodiments. Some professional terms and technical terms involved in the text have the same meaning as understood by ordinary practitioners in the technical field to which the application belongs.

[0025] Such as Figure 1-4 As shown, a new type of sound barrier containing a resonant cantilever beam of the present invention includes an upper, middle and lower three-part structure. The upper structure is the same as the lower structure, which is a combined sound-absorbing and insulating barrier board; the middle part is composed of a fixed sound-insulating frame 2 and a transparent plate 3.

[0026] Wherein, the combined sound-absorbing and insulating barrier board includes a protective panel 1 , a sound-absorbing column 8 , a resonant cantilever beam 6 and a sound-in...

Abstract

A novel sound barrier with a resonance cantilever beam comprises an upper structure, a lower structure and a middle structure, wherein the upper structure and the lower structure are composed of combined sound absorption and insulation barrier plates, and the middle structure is composed of a fixed sound insulation frame and a transparent plate. The transparent plate and the up-down combined soundabsorption and insulation barrier plate are connected into a whole through the fixed sound insulation frame, and the transparent plate has a certain sound insulation effect besides providing a certain observation visual field for running traffic vehicles. The resonance sound absorption structure such as the resonance cantilever beam is applied to the sound barrier for the first time, the noise reduction effect of the sound barrier can be further enhanced, and the influence of traffic noise on life of people is reduced to the minimum.

Description

technical field [0001] The invention relates to the technical field of sound-absorbing and insulating barriers, in particular to a novel sound-absorbing and insulating barrier containing resonant cantilever beams. Background technique [0002] In recent years, with the rapid development of my country's highways, railways, urban expressways and urban rail transit and other transportation infrastructure, although it provides convenience for people's travel, the accompanying noise problem has become more and more prominent. In some areas, there is even a phenomenon that the transportation infrastructure "convenience to the people also disturbs the people". Therefore, it is imminent to solve the problem of noise pollution. [0003] At present, the most effective way to solve the problem of traffic noise pollution is to install sound barriers on both sides of roads and railway lines. The traditional sound barrier works in a relatively simple way: one is guided by sound absorptio...
