Environoise consultants are proficient in the use of noise modelling software. We create noise models and sound maps for environmental noise, building acoustics, factory noise and sound insulation prediction. Our consultants offer this service as a stand-alone but more frequently we include acoustic models as part of our comprehensive reports. We use Soundplan, CATT, Softnoise and Insul to complete our service.
Soundplan 3D Propagation Noise Model
We predict the outdoor propagation of noise including façade incident noise levels such as from road traffic or industrial plant using Soundplan. The software is also useful to evaluate the attenuation provided by screening. The model takes into account the amplitude and frequency content of the noise and calculates the resulting noise. It accounts for how noise is attenuated by topography, existing buildings and proposed new buildings. We can ‘Value Engineer’ a proposed new building by accurately determining the shielding effect offered by the building. This means that the façade attenuation performance can be tailored to meet the predicted external noise level.
