Noise barriers are essential components in soundproofing and acoustic management, designed to mitigate noise pollution in a range of different industry environments. These noise barriers work by blocking sound waves, providing an effective solution to reduce the intrusion of unwanted noise. Their application spans across numerous sectors, including architectural designs, industrial settings, transport infrastructure, and urban development projects, demonstrating their versatility and importance in creating quieter, more comfortable spaces.

Innovative materials and technologies have significantly improved the effectiveness of noise barriers. Products like flexible noise barriers, fire-resistant barriers, and reinforced barriers offer customisable solutions tailored to specific needs. These barriers are not only effective in reducing sound transmission but also come with additional benefits such as thermal formability, fire resistance, and enhanced durability. The choice of material and design depends on the specific requirements of the project, including the type of noise to be mitigated, environmental conditions, and aesthetic considerations.

Understanding noise barrier technology

Understanding the technical aspects of noise barriers, such as sound transmission loss (STL), sound transmission class (STC), and the weighted sound reduction index (Rw), is crucial. These metrics help in evaluating the performance of a barrier in attenuating airborne sound. Factors like the mass of the barrier and its thickness play a significant role in its soundproofing efficiency, governed by principles such as the Mass Law. However, challenges such as the critical frequency of partition materials can impact performance, highlighting the need for internal damping and material diversity to optimise sound reduction.

The development and installation of noise barriers require careful consideration and expertise to ensure they meet the desired soundproofing objectives. With advancements in material science and acoustic engineering, it is possible to design thin partitions that offer high sound insulation levels, demonstrating that effective noise mitigation can be achieved without compromising on space or aesthetics.

Noise barrier products

Megasorber noise barrier is designed to block out or attenuate un-wanted sound, with noise blocking performance of up to STC (or Rw) 30

Our engineers have developed three different noise barrier products, each suitable for different application types. From installation inside walls and ceilings to a heavy-duty industrial noise curtain, Megasorber has a barrier for most project types.
