- Noise maps serve to meet the requirements of Decree-Law 292/2000;
- Noise maps are used to obtain certification ISO14000 or EMAS / environmental license IPPC;
- Noise maps are used to show to third parties (auditors, supervision, NGO) compliance with legislation noise when measurements are inconclusive;
- The noise maps are useful in situations where there is difficult to stop the activity. Give the possibility to use the alternative method of APA; measure ambient noise and calculate particular noise / residual noise;
- Noise maps are used to help solve noise problems with neighborhood;
- Noise maps are used to identify the main sources of noise;
- Noise maps help in the definition of noise control action plan, Municipal Plans for Noise Reduction, with objectives, budget and schedule set.
Our extensive development experience of Urban and Transport Planning noise maps is the answer to guarantee its technical and legal requirements,pt
Noise maps – Urban areas and Transports
Noise maps are a realistic approach to managing the acoustic impact on the environment
The Noise map is a graphical representation of the spatial distribution of the outside environment noise levels , becoming a diagnostic tool, revealing in detail the noise emissions, the influence of different sources and the population exposed to these.
The vast experience of dBwave.i in the preparation of noise maps is to guarantee the best response to their needs assessment and planning.
The dBwave employees have in their portfolio over:
100 municipalities in Portugal and Spain
10.000 Km2 calculated
3 million people covered
The noise-mapped according to the calculation, shorten the duration of data collection and reduce costs, besides introducing as fundamental advantage the opportunity to assess which part of the recorded sound comes directly from the source and which part comes from the different surrounding acoustic reflections.
These new simulation techniques are possible by increasing the capacity of computers, understanding and international standardization of the different forms that a source can generate a sound, the understanding of sound propagation effects by different means and materials and to standardize the calculation models.
By using these simulators, we can come to predict noise levels that occur in any acoustic scenario present or future.
The application of calculation methodologies allows to differentiate the noise sources and the extent to which each contributes to the noise level in each area of an urban center.
This makes it possible to compare the relevance of each source in the noise pollution of the city and to identify the variables which can act to reduce the impact of each.
