Polycarbonate Noise Barrier | Acrylic Noise Barrier

Polycarbonate Noise Barriers

Leading polycarbonate noise barriers manufacturer & Supplier in India. Acrylic noise barrier, Transparent noise barrier. Highway transparent noise barrier From Ecotone.

ECOTONE™ Sound barriers are most effective at mid-and high frequencies, while low-frequency sounds may require the use of longer and taller sound walls for mitigation. While the sound insertion loss of a sound barrier can be limited, it can be often optimized to provide a sufficient reduction of the offensive sounds. The height and length relationship of sound barriers is well documented. At a minimum, the sound barrier should at least block the line of sight between the sound source and the receiver. Additionally, the sound waves that travel around the ends and over the top of the sound barrier can be significant, as well as the sound waves reflecting off of other nearby buildings and structures.

There are mainly two types of Noise Barrier:

1. Absorptive Type (sound absorbent materials and possible finishes of absorptive panels)
2. Reflective Type (Transparent & Non-transparent)

Sound barriers reduce the noise which enters a community from a highway by absorbing, reflecting, or forcing the sound to take a longer path over and around the barrier. Sound is an energy that decreases in intensity as it travels away from its point of origin. Sound waves travel out in all directions from vehicles on the roadways. When the sound waves encounter an obstacle or barrier, some of the sounds will bounce off the barrier’s surface. This is called Reflection. If the surface is porous, where there are small cavities or holes that extend into the interior of the barrier material, a portion of the sound waves will travel inside the cavities when they reach the surface. The waves will bounce around and eventually expend all their energy. This process is called Absorption.

ECOTONE™ Polycarbonate / Acrylic Sheet Noise Barrier offers a comprehensive range of Polycarbonate Solid Sheets, Polycarbonate Embossed Sheets, and Acrylic Sheets which are made of high-quality raw materials. Our range offers maximum levels of glazing performance where transparency or tailored light transmission along with high impact strength is of vital importance. The transparent barriers are made of PMMA (polymethylmethacrylate) OR polycarbonate Sheets, placed between support railings. Moreover, these Polycarbonate Embossed Sheets, Polycarbonate Compact Sheets, and Acrylic Sheets are clear in color and available in various thicknesses, lengths, and colors to opt for.

These barriers are solely for isolation and meet the strictest criteria of the European standards EN 1793 regarding devices for the reduction of road traffic noise.

On-demand, they are colored, translucent, inclined, or wrapped around. They perfectly integrate with other types of barriers.

The polycarbonate noise barrier is a good alternative among many types of soundproofing barriers. Although glass-like appearance, it is virtually unbreakable and will not deform or crack when cut, drilled, or milled using the right tools.
Polycarbonate noise barrier significantly lowers noise level as well as not break natural views.

Ecotone Systems is a supplier of a polycarbonate noise barrier in India.
