Environmental and Facade Noise Modelling
Environmental Noise Modelling is the process of simulating and predicting the propagation of noise in outdoor environments. An environmental modelling technique combines geospatial analysis, prediction algorithms and simulation software to model noise propagation. This aids in impact assessments in evaluating potential noise impacts of new developments and early mitigation planning for noise control.
Noise Sources
- Transportation: roads, railways, airports
- Industrial: factories, plants and machinery
- Construction: Temporary noise from building and infrastructure projects
Facade 3D Noise Modelling, a technique commonly used in Noise Impact Assessments (NIA), predicts the noise levels that impact building facades and determines the amount of noise that penetrates the building’s exterior.
This modelling technique analyses various factors:
- Facade materials used in building construction and their acoustic properties.
- Building geometry, shape and orientation of building relative to noise sources.
- Window and ventilation opening which are critical points for noise ingress.
Environmental noise modelling assesses the broader impact of noise sources on the environment, aiding in planning and mitigation efforts. Facade noise modelling focuses on the interaction between environmental noise and building exteriors, guiding the design of facades to ensure indoor acoustic comfort. This is useful in building design as we can design facades to achieve desired indoor noise levels and assist in urban planning to minimise exposure for new buildings.
