Environmental Noise Impact assessment

Predicting noise damage in residential areas and shopping areas near a construction site of plants through simulation and maintaining a silent noise environment by reflecting anti-noise measures in entire process, from design through verification, in order to take optimal measures.

Necessity
01
Prediction of places where civil complaints may arise
Analysis of noise damage through accurate noise prediction
Evaluation of noise environment in a newly constructed site or a site to be scheduled for construction
02
Economic feasibility
Dramatic reduction of double investment and additional construction costs thanks to optimal anti-noise measures design
Pre-evaluation of noise variation by measures
03
Prevention of environmental problems
Maintaining a silent noise environment in residential areas
Prevention of civil complaints
