Tall concrete walls span more than 3 thousand miles of roadway across the US, separating suburban neighborhoods from noisy multi-carriage roads, representing half a century of traffic noise control efforts. While these giant noise barriers have provided acoustic protection for countless homes across the country, they have also inadvertently exacerbated the impact of traffic noise for many hapless citizens.
New technology currently being tested in the field in the United Kingdom shows promise in taking highway noise control to a new level, at long last. Successful demonstration of the noise wall technology could change the future of highway design, and drastically improve quality of life for thousands of people around and the world.

While noise attenuation measures should certainly be taken in any construction, refurbishment, build-out, or renovation settings, works that are undertaken inside buildings and within closed spaces are often less noisy to the public, given that everyone outside the building already falls in the acoustic shadow of its walls. On the other hand, in an outdoor context, any noise produced by construction activity can spread far and wide, potentially disturbing a considerable number of nearby residents and local businesses.
Acoustic panels are the best way to tend to a wide variety of noise control problems. Whether your construction activities are exceeding legal limits or a generator unit is bothering neighboring residents and local businesses, acoustic panels can attenuate the noise level and offer protection, relief, peace, and quiet. There is one issue, however: many of the most acoustic panels and acoustically-absorbent materials are also great at absorbing water and moisture. This is problematic on multiple levels:
We can all benefit from quieter equipment on worksites. Air compressors are an example of just one of the hundreds of pieces of equipment that make legally dangerous levels of noise. More powerful models of air compressors can reach 100 dB or more, while 85 dB is NIOSH’s recommended exposure limit, beyond which point permanent hearing damage can occur.
HVAC noise complaints are far from a rarity; businesses and authorities all around the world receive complaints from office workers, neighbors, and other businesses suffering from disturbance caused by the noise generated by HVAC units on rooftops and in compounds. A large array of HVACs can reach problematic noise levels even in the absence of typical issues such as duct system noise, loud return grilles, and high air velocity, often exceeding 85 dB in larger systems. To reduce the impact of HVAC noise on the external environment, noise barriers can be applied to the perimeter of the unit or a series of units.Read more →
It’s no secret that demolition is messy business. Pulling down entire structures is inevitably going to disturb surrounding residents, businesses, and pedestrians. There are also considerable health risks associated with the presence of dust from demolition.Read more →
