Highway walls are expensive running more than 2 million per linear mile for one side of the highway rymer said.
Highway sound barrier walls cost.
Between 2008 and 2010 roughly 554 million worth of sound walls were built.
A highway sound barrier is an exterior wall built alongside a roadway or highway that interrupts the flow of sound waves from one area to another.
It is a wall.
The concept of the sound barrier and how it works is remarkably simple.
The height width and location of the noise barrier wall dictates the size and shape of your noise shadow.
Newer research proves concrete sound barrier walls are some of the worst offenders for creating unwanted and unpredictable reflected noise issues.
Noise wall costs current construction costs average 51 61 per square foot.
For me though the most astounding figure in the story is that some.
The sound waves hit the wall and the reflective surface of the concrete causes the sound wave to go in the opposite direction.
The low installation costs of concrete sound walls leads to an economical buy when compared to metal or wood noise barrier wall applications the sierra wall noise barrier wall system has the additional advantage of being relocated if highway boundaries change.
Two types of highway sound barriers are used.
A hard surface made of wood concrete brick or other reflective strong and durable material.
The total spent on sound walls through 2013 the most recent government figures tops 6 billion.
Take a peek at the soundwall project showcase.
When constructing an acoustic wall to eliminate highway noise.
Disadvantages of concrete highway barriers.
This translates into a fourteen foot high wall typical costing about 3 9 million dollars per mile.
This gabion wall s surface diffuses and reduces the traffic noise the noise is unable to go under or through the wall.
According to the federal highway administration the average cost of building a sound wall is 30 78 per square foot.
Each state has a different threshold for what triggers the need for a reasonable intervention.
The barriers are largely made of concrete and cost over 2 million per mile with some 6 billion spent on them through 2013.
1 866 231 7867 ail sound walls designs and manufactures cost effective pvc sound barrier wall systems that are engineered for maximum sound reduction.

Construction costs for rural barriers may be lower and urban barriers may be much higher.
This creates an acoustic sound shadow behind the wall.
