Abstract
The utility model discloses an efficient noise reduction barrier, which belongs to the field of environmental protection facilities. The efficient noise reduction barrier consists of a porous front-panel, a sound absorption middle plate, a hollow cavity rear plate and a frame, and is characterized in that the porous front-panel is a through-hole plate which is distributed in a netted way, through holes are trumpet-shaped, and have big calibers at the external surface of the front-panel and small calibers at the internal surface of the front-panel, the porous front-panel, the sound absorption middle plate and the hollow cavity rear plate are sequentially connected with one another, and the peripheries of the porous front-panel, the sound absorption middle plate and the hollow cavity rear plate are fixedly assembled in the frame. The efficient noise reduction barrier of the design creatively adopts the porous front-panel which is distributed in the netted way and consists of the trumpet-shaped through holes, the trumpet-shaped through holes have the big calibers at the external surface of the front-panel and the small calibers at the internal surface of the front-panel, the porous front-panel is combined with the sound absorption middle plate which contains sound absorption materials and the hollow cavity rear plate, so a resonant sound absorber with a wide frequency range is formed and basically covers the highway noise frequency range, and the functions and effects of sound absorption and noise reduction of the noise barrier are greatly improved.
Description
Technical field
The efficient noise reduction sound barrier of the utility model.Belong to the environmental protection facility field.
Background technology
Along with the develop rapidly of Chinese transportation transportation and urban construction, more and more serious because of the sound pollution that the vehicle flowrate noise causes, and noise is directly connected to people's quality of life, and people's physical and mental health is caused harmful effect.For reducing sound pollution, more generally adopt the sound barrier facility in recent years.But, the frequency noise narrow range that existing sound barrier absorbs, acoustically effective is not very desirable.
The utility model content
The purpose of the utility model provides a kind of efficient noise reduction sound barrier, to satisfy the sound absorption noise elimination demand to the broad range frequency noise, promotes the sound absorption reduction efficient of sound barrier.
The utility model purpose realizes through following technical scheme:
The efficient noise reduction sound barrier of the utility model by plate, cavity in porous panel, the sound absorption after plate and framework form; Characteristics are that porous panel is the ventilating hole plate of net distribution; This through hole is horn-like, is heavy caliber at the external surface of panel, and inner surface is small-bore; In porous panel, the sound absorption behind the plate, cavity plate be linked in sequence, its periphery is installed in the framework.
The porous of being made up of tubaeform through hole that the creative employing of the efficient sound barrier of the design is net distribution is a panel; Its tubaeform through hole is big at the external surface bore of panel; The inner surface bore is little, this porous panel be equipped with in the sound absorption of sound absorption material that plate makes up behind the plate and cavity, formed a kind of resonant sound absorber of wide frequency range; Basically cover the frequency range of highway noise, significantly promoted the sound absorption reduction function and the effect of sound barrier.

Specific embodiments
This novel sound barrier by plate 2, cavity in porous panel 1, the sound absorption after plate 3 and frame-saw 4 form; Porous panel 1 as shown in Figure 1 is the ventilating hole plate of net distribution, and this through hole 1a is horn-like, is heavy caliber 1c at the external surface of panel; Inner surface at panel is small-bore 1b; In will absorbing sound behind plate 2 and the cavity plate 3 be connected with screw 5, again plate 2 in surface within the porous panel 1 and the sound absorption is bonded to one, then its periphery is installed in the framework 4.
Produce when implementing, according to the specification needs, the aluminium alloy plate of plate 3 employing different-thickness behind plate 2, the cavity in porous panel 1, the sound absorption, framework 4 adopts channel-section steels.
Claims (2)
