Existing sound measuring equipment are mostly designed for indoor use, and those of outdoor are costly and demands human involvement multiple times. This study proposes the concept of a compact and cheap sensor and GIS-based system that runs algorithms of sound distribution and visualizes interpolated and extrapolated data as heatmaps in an interactive map. According to the concept, the system consists of several noise measuring devises wirelessly connected to a data collector that transmits the measurement data real-time through internet to a server, where the data is analyzed and visualized. The integrated into GIS algorithms are designed to identify the sound sources and locations where the sound level exceeded its daytime or nighttime standard limits. The implementation of proposed concept may make noise issues related to construction activities more transparent.
