• Abstract:
  Noise barriers are a necessary structure along the highway to protect the local residents from excessive
  
  road noise. There are many different materials from which noise barriers can be constructed. As of 2004, the
  
  most widely used noise barrier material was concrete which accounts for approximately 80 percent of all the
  
  noise barriers in the United States. Other noise barrier materials include metal, plastic, wood or soil. Each of
  
  the materials used to construct noise barrier has advantages and disadvantages both acoustically and
  
  aesthetically.
  
  This study was done to determine which of the currently used noise barrier materials in Ohio produced the
  
  largest noise reduction. There were seven different materials field tested across the State of Ohio; absorptive
  
  concrete walls, reflective concrete walls, hollow fiberglass walls, rubber-filled fiberglass walls, steel walls, clear
  
  walls and earthen berms). The noise barriers were tested by measuring noise levels in front of the barrier,
  
  above the barrier and behind the barrier, while recording traffic data (volume, class, and lane position) and
  
  atmospheric conditions. The noise reduction results across the various barrier materials were then compared to
  
  determine which material yielded the greatest noise reduction. The TNM parameters were set to replicate each
  
  site that was tested and the noise reduction results from the model were recorded. The results from the model
  
  and the field were then compared to determine if the model is an accurate representation of the field.
