Description:
Cellular Expert Express Sound is a specialized geospatial simulation engine developed for the accurate modeling of environmental sound propagation, with a particular focus on the behavior of acoustic warning systems such as civil defense sirens. Built as a server-side module within the ArcGIS Enterprise environment, it offers scalable, multi-user access and centralized data management, allowing organizations to plan and evaluate siren network performance across wide geographic areas. At the heart of the solution lies a full implementation of the ISO 9613-2 standard, the internationally recognized method for calculating sound attenuation during outdoor propagation. This ensures that all simulations comply with established acoustical engineering practices, accounting for atmospheric absorption, ground effects, terrain shielding, and obstacles such as buildings and vegetation. Designed for agencies responsible for public warning infrastructure, emergency preparedness, homeland security, and municipal safety planning, Server-Express Sound provides detailed modeling of how siren-generated sound behaves across real-world terrain. The module enables users to place siren sources into a geographic environment, define their acoustic properties (sound power level, directivity, frequency spectrum), and then simulate how the sound will disperse over urban or rural landscapes. The result is a highly realistic acoustic footprint presented as a sound pressure level (SPL) raster map, visualized directly within GIS. This solution supports not only the assessment of coverage zones where sirens will be clearly audible, but also the identification of acoustic shadows and weak coverage areas. It facilitates scenario comparisons – for example, to evaluate the impact of alternative siren placements, sound output configurations, or system upgrades – making it an essential tool for cost-effective, performance-driven siren system design. By combining GIS intelligence, standardized acoustic modeling, and enterprise accessibility, Cellular Expert Express Sound delivers a highly reliable and efficient platform for organizations tasked with ensuring audibility, safety, and public communication readiness in both peacetime and emergency situations.
