Sound Study for Proposed Firing Range Sites

Shield was retained by North Carolina Wildlife Resources Commission (NCWRC) to perform a sound study to collect sound data in the area of multiple proposed firing range sites in order to understand the levels of sound emanating from each of the proposed sites. For this study the NCWRC Law Enforcement Officers discharged pistols, rifles and shotguns at the proposed firing range sites. Multiple sound level measuring locations were located in the general vicinity of nearby residents in order to measure sound levels if a firing range should eventually be constructed at one of these sites.  Type 2 impulse sound level meters were used to record sound levels before, during, and after discharging weapons.  Extraneous noises (train horn, traffic, chainsaw, etc.) were recorded at each location throughout the measuring period.  

 

Shield established a correlation between peak sound levels and distance from the firing range at the proposed firing range sites. In summary the sound levels emanating from the firing of weapons at proposed firing range sites did not produce sound levels at any of the monitoring locations any greater than those sound levels emanating from extraneous sounds recorded during the sound study, and any other typical sounds that could be experienced at other times in those areas where the sound measuring was conducted.   

  

The sound data presented in this study was made available to NCWRC to assist in the design of the proposed firing range sites and to provide empirical evidence of the extraneous noise nearby residence would likely encounter if firing range sites were to be constructed.
