Environmental Noise

INERTANCE has performed the environmental noise assessment to be in line with applicable local environmental noise limits against transportation and industrial noise around residential area.

Site & Road investigations are carried out to predict the estimated noise level during day & night time, which can be shown as noise contour map respectively, and it is determined if the noise contour measure as anti-noise facilities (ex. Barrier) should be designed.

Noise contour map is used to understand the noise status propagated around interested area, which is often verified via noise verification survey. INERTANCE has a capability to perform below kinds of noise study.

  • Noise Pollution
  • Local Regulation of Noise
  • Health Effects from Noise
  • Noise Contour Map
  • Noise Exposure
  • Noise Source such as Vehicles, Aircraft, Trains and Industrial Sources
  • Sound Pressure Level (SPL) and Sound Power Level (PWL)
  • Definition for Residential Area
  • Noise Induced Hearing Loss
  • Definition for Maximum Allowable Noise Level
  • Background Noise
  • Propagation of Sound
  • Noise Analysis
  • Environmental Noise Control

1.Noise Assessment

INERTANCE provides the powerful noise contour map using relevant simulation tools, which is generated by various noise sources such as transportation, industrial and recreational activities around residential area. Noise assessment has to be carried out to estimate the noise pollution to check the compliance with local noise limitation.

2. Road Traffic Noise

Road traffic noise is the most important source of environmental noise, and INERTANCE has investigated the noise pollution caused by transportation such as vehicle, truck during day & night time in order obtain the result which can be used to verify the noise prediction shown in a contour map.



3. Railway Noise

Railway noise is a major noise source normally in a big city, generated by moving and long line vehicles such as train or subway.

4. Construction Noise

Construction noise is a significant problem in compact big city, and it is normally controlled by local regulations. The noise assessment based on survey is conducted to adjust the construction activities so that the noise severity can be mitigated.
