Noise propagation 3D modeling
Our experience
The team of “Eco-Spectri” LTD has
a long working experience in the field of 3D modeling of noise
propagation. The Company has been providing measurement services
both, on the territory of Georgia and beyond its borders both, for
state bodies and international financial institutions (Asian
Development Bank, European Investment Bank, World Bank, European
Bank for Reconstruction and Development, etc.). The company has
completed modeling projects for the propagation of highways,
railways, power lines, industrial, construction and other types of
noise.
When is noise propagation
modeling needed?
- In urban planning;
- During the road and railway construction and operation;
- During the construction and operation of wind power plants;
- In case of industrial and commercial activities;
- For noisy working zones;
- For urban noise;
- In the planning, realization and/or operation phases of infrastructural projects;
- In developing environmental management plans.
Services we
offer:
- Noise propagation modeling in working zones;
- Road and railway transport noise propagation modeling;
- Power transmission lines and wind power plant noise propagation modeling;
- Production/industrial noise propagation modeling;
- Modeling of point and linear noise sources propagation (stationery sources, pipelines, etc.).
Methods and techniques of
noise propagation modeling
Noise modeling is done by using
German „CadnaA“ software. „CadnaA“ (Computer Aided Noise Abatement)
is the state of art efficient software for calculation,
presentation, assessment and prediction of environmental noise. The
software has more than 30 standards and guidelines, powerful
calculation algorithms, extensive object processing tools,
outstanding 3D visualization. It is totally compatible with other
Windows applications, such as Word processors, table calculation
software, CAD and GIS database.
Standards used in noise
propagation modeling:
- Vehicle noise - NMPB-1996 (Nouvelle Méthode de Prévision Emission Parameter du Bruit) – the European Commission recommended French Auto-Modeling Standard;
- Railway noise - SRM II (Standaardrekenmethode 2) - the European Commission recommended Netherlands Railway Modeling Standard;
- Industrial and other noise - ISO 9613 (Acoustics — Attenuation of sound during propagation outdoors).
Duration and prices of
measurement and analysis services of the noise propagation
modeling
The time and price of the
services are calculated individually, depending on the numbers of
measurement points, task complexity and scale, as well as specific
indicators and environmental conditions.
