Compute the noise level in your city

The NoiseM@p experience...

Made by research

The NoiseM@p project is led by two French research teams, internationally recognized in their field of expertise, the Lab-STICC (UMR CNRS 6285) laboratory for geospatial research and the Environmental Acoustics Laboratory (Ifsttar) for environmental noise research.

Designed for GIS

NoiseM@ap is a fully GIS-implemented environmental noise calculation model, as a plugin of the OrbisGIS software.

Free to use

NoiseM@ap is distributed under the GPL 3 license and can be freely used whatever the field of application (research, education, business...).

logoTHE PROJECT


The NoiseM@ap project started within the reasearch project Eval-PDU, funded by the French National Research Agency (ANR) in 2009. During the project, it was decided to produce a tool that would be fully implemented in a GIS software, in order to produce noise maps for evaluating the noise impact on urban mobility plans. It was expected to propose an alternative of commercial software, as a free tool, which will be able to produce environmental noise maps on very large urban areas, requiring few computational resources, while providing relevant results. This tool was integrated in the OrbisGIS software and applied with success to the study the noise effect of several mobility plans of the Nantes metropolis.

Since this first study, many developments have been focused on NoiseM@ap, in order to enhance both the noise calculation method and its integration within a full and simple system dedicating to environmental noise evaluation (data managing, noise exposure calculation, interactive noise maps...). The future of NoiseM@ap is to become a reference tool for a large community (researchers, students, teachers, engineers...) in order to predict, to manage, to study... environmental noise.


DESIGNED FOR ACOUSTICIANS, RESEARCHERS, TEACHERS AND STUDENTS


Because NoiseM@p is easy to use and opensource, it is a perfect tool for the noise assessment in urban areas in the context of the european directive 2002/49/EC. In addition, it can be an excellent support for academic training, as well as for research.



METHODS



The noise calculation method implemented within the NoiseM@ap plugin is based on the standard French method called NMPB 2008, as a reference method to be used under the Directive 2002/49/EC relating to the assessment and management of environmental noise (Read More). In order to limit the overall computational time, the current version of NoiseM@ap implements a simplified 2D approach of the NMPB 2008 for the sound propagation calculation (Read More), as well as, a simplification of the noise emission (Read More). It must be noted that the current development of NoiseM@ap is aimed at full integration of the NMPB 2008, including all 3D propagation phenomena, such as ground effect and horizontal scattering by building edges. Most of algorithms within the NoiseM@ap plugin, mainly for the calculation of the sound propagation, are based on spatial analysis methods which allow to optimize and to reduce the complexity of the sound propagation path search in urban areas. Each part of the computation process has been splitted in several SQL functions thanks to the H2GIS datatabase available within OrbisGIS. This open tool-box help the user to produce noise maps beyond the limitation of a monolithic computation software. However, the GIS environment allows to produce noise results with a high level of graphical representation, by coupling if necessary with other geospatial databases such as demographic data. Using GIS analysis methods, the user can easily compute a map of population exposure. This map is estimated by determining the number of residential units for each building and the number of inhabitants by units such as french statistical population units (INSEE) or cities boundaries.






ARCHITECTURE



NoiseM@p consists of two separated parts : NoiseM@p core and NoiseM@p plugin.

NoiseM@p core

This module contains the main processes to compute the sound level and to produce noise maps. The first part is related to the evaluation of the noise emission, by considering light and heavy vehicles, as well as trolley cars (road noise). The second part consists in evaluating the noise propagation from sources to receivers, according to the standard model described below. The main inputs of the propagation model are :

  • an array of sounds sources defined by a geometry (lines or points) and a sound power for each third octave band from 100 Hz to 5000 Hz,
  • an array of buildings (2 D geometry),
  • a list of parameters, like the order of reflexion and diffraction, wall absorption, maximum propagation distance... that are needed for the calculation of the sound attenuation between sources and the receivers.

This module written in JAVA is exposed as a set of SQL functions to the OrbisGIS software. It uses the relational database management system (RDMS) H2 and its spatial extension called H2GIS.

NoiseM@p plugin

The NoiseM@p plugin offers an unique way to connect the NoiseM@p core processes within the OrbisGIS software, available as SQL functions. These functions are manipulated in a graphical user interface console that enables you to execute NoiseM@p commands. This console also proposes a number of features for helping with, code formatting, code writting (auto-completion, tooltips)…

However, the main added value is related to the GIS capabilities - map viewing, cartography, data edition, database access - that permit to interact with the input and output data. For example, the user can easily post-process the output data through the built-ins OrbisGIS functions, in order to :

  • interpolate the receivers levels to build a continuous noise map (ISO levels),
  • establish a spatial statistical study of the results in association with external data to compute population exposure,
  • publish intermediate or final results as files and/or over networks services thanks to the OGC standards supported by OrbisGIS.

Future

NoiseM@p is a high performance computational and programming tool to access the outdoor noise exposition in urban areas, as well as to realize researches and courses on the noise problematic. Because of many partners want to use NoiseM@p, new features will be added in the next months thanks to research projects like ENERGIC-OD.

  • the use of NoiseM@p by experts will be improved by developing user interfaces: one can add, for example, specific tools for manipulating input data and for producing standard noise indicators automatically,
  • NoiseM@p will take advantage of its modular architecture to be pushing on cloud-enabled system. We attempt to provide a design and architectural framework for web applications based on open geospatial standards. The NoiseM@p processes could be executed through a WPS implementation and the involved spatial data conform to the standards of an SDI to meet their INSPIRE obligations (web services).
  • the use of Open Data (such as road traffic), could be both a simple and a low-cost solution for cities to produce noise maps in "real-time" and to communicate with citizens on their urban soundscape.

Many applications of NoiseM@p are also possible in order to reduce the noise exposition of citizens... The new features and applications are in progress. So keep in touch and follow us.
