All our products are tested for performance and durability to rigorous scientific standards, in both the lab and the field. Independent research proves Echo Barrier are the best-in-class, leading the way in the reduction of noise pollution.
It is our technical excellence and scientific approach that keep us ahead of the pack. Through meticulous design our acoustic engineers have crafted six components that define our performance in the field.
Our acoustic barriers are manufactured using high specification absorbent materials. These materials are truly effective, soaking up as much as 100% of sound at the integral 300 Hz-1kHz range. The barriers reduce both reverberation and sound reflection, creating a sound suppression barrier. Alternative solutions tend to reflect or reverberate sounds, creating a sonic backwash that leaves more noise pollution than before.
Our solutions are manufactured using materials that absorb sound—but not water. All our acoustic barriers are certified as 100% waterproof. Water distorts and diminishes the effectiveness of textile-based solutions like foam, rock wool and fiberglass by up to 50%, as they soak up the rain until saturated. Water saturation makes installation and transportation far more problematic, denting productivity.
Rigorous testing proves that our solutions offer unrivaled field attenuation, and cut noise by a remarkable 41dB in the lab. Given that our products are 50% lighter than alternatives this is impressive. The lab tests don’t lie.
While heavier materials may reduce vibration—mass alone cannot stop sound.
As sound travels in all directions up and over the barriers—we design products that hit that sweet-spot, where sound is absorbed but products are still lightweight.
The barriers can be doubled up if necessary—increasing their performance six fold.
Our barriers are built to last and withstand all conditions, certified from -40ºC to +70ºC, waterproof, and UV resistant. Our barriers are the most durable on the market, built to last the distance and maintain performance, wherever they are placed. Vitally they will keep looking the part too, maintaining their appearance. Research proves that perception matters—the public complain far less when fencing looks smart and in good condition.
The location of noise barriers relative to the sound source—called site geometry—is the prime factor in any noise control system. As a general rule the closer to the sound source the barriers are the better they perform, enhancing attenuation.
When a barrier is close to a sound the sound is said to be under the barrier’s ‘acoustic shadow’. If you place a barrier between noise (eg a jackhammer) and a location (eg a building) you create an acoustic shadow.
The closer a barrier is to the sound the bigger the acoustic shadow becomes, and the less the noise that can escape it.
As Echo Barrier products are lightweight and portable, they can be moved to cast the optimum acoustic shadow, and maintain the perfect site geometry as the project progresses.
The critical range in noise control is 300Hz-1000Hz. A noise control barrier must absorb as much sound as possible over this range if it is to be considered effective. Tested in the field, our barriers average a remarkable 77% efficiency over the crucial range. Considering our products are half the thickness and much lighter in weight than alternatives our competitive advantage becomes clear.
All Echo Barriers are designed with the end user in mind, they are easy to store, transport and install making for maximum site efficiency
What makes our acoustic barriers work?
Let’s take a look under the hood to understand how our temporary noise control barriers deliver market-leading performance at minimum weight.
Waterproof outer layer
Extremely durable and waterproof, highest quality PVC makes our acoustic barrier easy to clean and professional looking.
Top grade lightweight acoustic absorbent made from recycled material prevents sound from reflecting off the barrier.
Waterproof breathable membrane
Allows sound to be absorbed but keeps water out.
Durable reinforced mesh
Extends product life to retain acoustic performance in harsh working environments.
Designed to be easy to use

There are two KPIs to measure a barrier’s performance.
- Transmission loss: this measures the difference a barrier makes by measuring sound with and without the barrier.
- Acoustic absorbency: over the key 300-1000Hz range how much sound is absorbed and how much is reflected or reverberated elsewhere?
By concentrating on one of these measures it is relatively easy for some barriers to perform well in the lab alone, but it is performance in the field that is vital.
Our barriers perform well under both measures, in lab and on site, in any conditions, even when wet. Other products lose integrity when the rain comes, but not Echo Barrier.
Our experience and design means our barriers actually perform better in the field than the lab when independently tested. The table below demonstrates results from a noise reduction project using a diesel powered trenchless excavation drill.
We were able to achieve 5dB less sound in the field than in the lab.
