Construction site noiseneeds to be properly managed because itaffectsthe health and safety of workers and nearby residents. Therefore, the authors attemptedto develop areal-time noise informationmapping system forconstruction sitesthat can support the establishment of noise reduction measures by practitionersusingspatial interpolation. Fieldconstraints were identified to ensure that the noise-estimation model has high accuracy without disturbing workers.Spatial interpolation was utilized to develop the noise-estimation model,and the performance was evaluated by installing sensors in an experimental environment according tothefield constraints. The model showed optimal performance,with maximum and minimum accuracies of 97.5% and 92.4%, respectively, when using eight sensingpoints as inputs. The research resultswerevisualized through the Unity 3D Engine for the convenience of field workers. Through the results of this study, practitioners will be able to easily understand information on high-noise areas that need to be managed, thereby minimizing the cost and time required for on-site noise management.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
