Sound Barrier Concrete Walls

The wood based material is lightweight averaging just 36 40 pounds per cubic foot.

Sound barrier concrete walls. Which is something that concrete walls could never offer. Excessive noise contributes to numerous health problems. Sound wall construction using concrete is an outdated technology. Reflective walls of solid concrete that create a barrier and push sound away from homes or other areas being shielded.

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. Newer research proves concrete sound barrier walls are some of the worst offenders for creating unwanted and unpredictable reflected noise issues. 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. This new technology provides many more benefits including mobility.

Concrete is a heavy material that poses numerous challenges while absorptive noise barrier walls are made with durable lightweight metals and non corroding materials. Concrete noise reducing barriers. 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. The easiest strategy is to add a second layer of drywall to build up a thick sound deadening barrier.

Precast concrete sound walls reduce the perceived noise by as much as half while absorptive treatments have been found to further reduce noise pollution. Softsound outdoor sound barriers are also 100 recyclable and environmentally friendly. The sound waves hit the wall and the reflective surface of the concrete causes the sound wave to go in the opposite direction. Deadening those vibrations is best done with heavy dense materials that stop noise in its tracks.

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. Newer wall systems are lighter easy to customize and work for a variety of applications. When it comes to heavy brick and stone are great but impractical for retrofitting your interior walls. Durable under all weather conditions our concrete sound walls are resistant to mildew insect nesting rotting termites and more.

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.
