When a material encounters sound waves, it can either absorb or reflect the energy. Acoustic absorption is the process through which sound energy is taken in by an object. When acoustic materials absorb this energy, they transform it into heat and transmit it. Thus, the energy is ‘lost’.Read more →

Acoustics – the science of sound – is something that can easily confuse the layman, especially given its “invisible” characteristics. At Echo Barrier, taking the laws of physics and applying them to effective noise abatement is what we do every day in both the design and implementation of our acoustic barriers and noise enclosures.
Equipment on a worksite is exposed to unforgiving conditions, and so whether its the hardware we use or the safety equipment we wear, it needs to be designed and built tough. A key part of retaining a piece of equipment’s durability is its maintenance, including cleaning.
It's easy to get lost between all the numbers, terminology, and data when dealing with sound, noise, and acoustics in general. After all, it’s not a simple science.
An acoustic shadow results when sound waves fail to spread outward due to disruptions or physical barriers such as buildings, geographical obstructions, or wind currents and can alter our perceptions of events, and can also be controlled to diminishing the impact of high decibel noises.
Upon considering noise attenuating barrier products like Echo Barrier, you may ask yourself: “I’ve been using hoarding for years, isn’t that blocking noise anyway?” Certainly, a small amount of sound is being prevented from passing through to the other side; however, not only is this amount a fraction of that reduced by Echo Barriers, but it is dangerously reflecting sound back toward the noise source and people exposed internal to the perimeter.
Furthermore, the cumbersome nature of heavier objects used in hoarding make installation, disassembly, and reuse far more difficult.Read more →
