Sound transmission class stc provides an estimate of the acoustic performance of a wall in certain common airborne sound insulation applications the stc of a wall is determined by comparing sound transmission loss stl values at various frequencies to a standard contour stl is the decrease or attenuation in sound energy in db.
Sound barrier concrete walls.
The sound waves hit the wall and the reflective surface of the concrete causes the sound wave to go in the opposite direction.

Durable under all weather conditions our concrete sound walls are resistant to mildew insect nesting rotting termites and more.
As clearly defined by the federal highway administration a noise barrier can achieve a 5 db noise level reduction when it is tall enough to break the line of sight from the highway to the receiver such as a home or person.
Versatile noise wall solutions using precast concrete.
The easiest strategy is to add a second layer of drywall to build up a thick sound deadening barrier.
Determining sound transmission class stc for concrete masonry.
Noise wall solutions using softsound and sierra wall technologies combine the unmatched strength and durability of precast concrete with a variety of finishes to provide a number features.
With color additives or stains and textured form liners a precast wall can blend in with a city s architecture and local topography or stand out by capturing community s theme or identity.
When it comes to heavy brick and stone are great but impractical for retrofitting your interior walls.
Excessive noise contributes to numerous health problems.
Deadening those vibrations is best done with heavy dense materials that stop noise in its tracks.
The wood based material is lightweight averaging just 36 40 pounds per cubic foot.
This new technology provides many more benefits including mobility.
Reflective walls of solid concrete that create a barrier and push sound away from homes or other areas being shielded.
While both the federal and state governments have made efforts to address the issue of highway noise and its adverse impacts on society their traditional remedy has been to place large sound reflective concrete barriers on the worst offenders.
Concrete is a heavy material that poses numerous challenges while absorptive noise barrier walls are made with durable lightweight metals and non corroding materials.
Precast concrete sound walls reduce the perceived noise by as much as half while absorptive treatments have been found to further reduce noise pollution.
Newer research proves concrete sound barrier walls are some of the worst offenders for creating unwanted and unpredictable reflected noise issues.
While reflective products like concrete have been the traditional material for noise barrier walls the advanced absorptive materials found in our sound barriers present a much more effective noise abatement option.
Which is something that concrete walls could never offer.
Softsound outdoor sound barriers are also 100 recyclable and environmentally friendly.
Sound wall construction using concrete is an outdated technology.
What makes our outdoor sound barriers so attractive is they serve as a protective security fence attractive privacy wall versatile sight barrier and as an economic retaining wall.
