This paper explores methods to help make shooting ranges compatible with surrounding properties. Sounds from outdoor firing ranges can propagate over 2 miles from the range depending upon topography, vegetation, background sound levels, numbers of shooters, weapon types, and mitigation systems employed at the range. Many communities have regulations for maximum sound levels that can be propagated from one property to another. The impulsive nature of gun shots produces sounds that are not easily measured using conventional acoustical metrics and sound level meters. These items can be studied using three-dimensional computer models. Acoustical data for different weapon types are used as the sound sources. Mitigation options such as shooting sheds, berms, and other strategies can be studied as part of the design process to optimize sonic compatibility with neighboring properties. Similar processes are used for partially and fully enclosed ranges with the addition of the walls, roofs, doors, and HVAC systems for the range included in the models. An architect, engineer, and other design team members work to design specific systems to provide the required mitigation methods. Consultants can evaluate the cost of implementing the mitigation measures so that sonic compatibility is addressed prior to using the range. |
