Necessity of Noise Map for Smart Protection from Environmental Noise

Abstract

Since environmental noise, which has recently increased disputes and complaints, has a negative impact directly or indirectly on the lives of modern people, accurate analysis of noise effects and establishment of noise reduction method are essential. In the view of prevention, the noise map is very important for observing the overall noise distribution, identifying the noise sources, and preparing a noise reduction plan. In Korea, technical studies had conducted for producing the noise map. Various efforts also applied to prepare noise reduction measures, efficient introduction of regional noise maps, and establishment of management systems. However, there was a lack of experts and budgets to produce the noise map. The noise prediction formula and program were not standardized yet, consequently that it was difficult to build an infrastructure and update it. In this paper, by making a noise map for Chuncheon city using a smartphone application, we tried to produce a brief version of the noise maps which would increase people’s perception and interest toward. Furthermore, we introduced several good examples of the noise map from other countries. We expect that it is possible to reduce social costs and to improve the quality of people’s lives by academically approaching the multifaceted relationship between environmental noise, hearing, and health in Korea.
