Environmental Noise
PNV addresses environmental noise issues of planned or existing facilities. Whether it is noise from air-conditioning equipment, construction, loading docks, emergency generators or other noise sources, environmental noise can impact people in proximity to these activities. Many municipalities have established standards to limit such noise. Phoenix NV can address environmental noise in the design phase of a proposed project. Sound power data from equipment manufacturers can be analyzed to determine whether or not proposed noise will meet standards. In the event of noise from currently operating equipment, PNV can conduct on-site measurements to determine compliance. In either case, noise mitigation features can be designed to bring equipment into compliance.
Phoenix NV uses the CadnaA noise propagation model to computer model a site and its surroundings. Such a model takes into account the source of the noise as well as the surrounding topography and building structures to determine the impact upon neighboring properties. This model can be used to delineate noise contours which indicate the extent of impact. When necessary the same program can then be used to design noise mitigating features such as sound walls to control the environmental noise.

For existing sources we measure and analyze the noise sources to determine impact relative to local noise codes, and when necessary develop noise mitigation features.
