FONOMOC – The main network for noise monitoring

FONOMOC is the FOcus group On NOise MOnitoring Cities. Aim of this group is to exchange knowledge and experiences on noise monitoring in cities. First meeting of FONOMOC was held in Gdansk. The second meeting was in Paris. FONOMOC is a subgroup of Working Group Noise EUROCITIES.

The objectives of the FONOMOC group are:

  • Exchange of knowledge en experience on noise monitoring systems
  • To carry out peer reviews (city to city)
  • To identify new developments and innovations
  • To identify and to collaborate in EU funded projects (H2020, LIFE, INTERREG and URBACT)
  • To promote noise monitoring and to elaborate and use Open Data

Report FONOMOC meeting Paris on 24 March 2017

After welcoming by chair FONOMOC and the director of Bruitparif (Ms Fanny Mietlicki) and an acquaintance round the minutes of the previous meeting (Rome) were approved.  Only a minor change of the area in Turin will be made (Murazzi instead of Mazurri). By Ms Patrizia Bellucci (ANAS) an update was given on the DYNAMAP project. This project is about dynamic noise mapping with the support of noise monitoring units (NMU). The system does not only updates the traffic noise maps in Rome and Milan frequently but also detects the anomalous noise not being caused by traffic by means of the so-called ANED algorithm. This algorithm is developed by the La Salle University of Barcelona. The frequency of refreshing the noise maps varies between 5 – 60 minutes depending on the hour of the day. In rush hours the refreshing frequency is 5 minutes. By means of a noise propagation model, the noise is estimated on grid points that do not have a NMU. This is done by the NMPB method, so DYNAMAP is CNOSSOS proof. Beside the LDEN and LNIGHT other indicators are also calculated. The NMU’s consist of a mix of low and high capacity sensors. From June the information is also accessible to the wider public by means of a website ( After the presentation and discussion the next presentation was held by Ms Rosalba Silvagio (ISPRA) and Mr Francesco Borchi (UNIFI). Subject of the presentation was the MONZA project. The MONZA project, a rather new initiative is about noise monitoring in Low Emission Zones. However, it is combined with air quality as well.  It follows a top-down and a bottom-up approach. The top-down approach is about designating pedestrian zones for instance. The bottom-up approach relies on meetings with the public, interviews and a competition for a logo. Within the MONZA project a method for noise measurements in LEZ will be developed. Noise measurements in the MONZA project is done by a mix of low-tec sensors and traditional devices. During the discussion on MONZA it was suggested that we need more time to consider whether a single standard (specifications) is needed for low-tec sensors.  This will be on the agenda in next meeting and prepared by Ms Rosalba Silvagio and Mr Cesar Asensio (University Madrid). By Mr Francesco Borchi an explanation was given about the technical components used in the MONZA project. The sensors are installed on streetlights and sometimes appllied with solar panels. Calibration is not remote but in situ. Attention was asked to provide the sensors/microphones with proper windscreens. More information about the MONZA project can be obtained at After this Mr Luca Nencinni presented the progress on the low cost sensor used in the DYNAMAP project (these sensors are also be used in the MONZA project). After testing two types of sensors (MEMS and electorate) it was chosen for an electret microphone/sensor. The threshold of these sensors is 32 dB(A). Sensor are sometimes installed close to the façades which can affect the noise level determined (reflection). How to deal with the influence of the façade is still under discussion in the projects. By Mr Richard Spaans (DCMR EPA) a presentation was given about the RANOMOS project that is running at Rotterdam-The Hague airport. Within this project noise complaints are connected to flight tracks and noise measurements which are executed around the airport and in the residential districts around the airport. Approximately 12.000 complaints are sent in annually by more than 800 residents. The module that supports all these functionalities is CASPER. More information about the RANOMOS system can be found at . After the lunch a presentation was given about the MONICA project by Mr Enrico Gallo. Tis project, a H2020 funded project, has 25 partners and is consisted of six pilots demonstarting the use of IoT technology helping and solving security and noise problems of large outdoor events, music events, festivals, sport events and other events that attract more than 100.000 persons. Wearables and portable IoT sensors, also smartphones included, are employed in this H20202 project. Mr Gallo focussed on the situation in Turin, especially on the San Salvario Movida district. This district can be characterised by a mix of open air night life every weekend, long-time running, with about 40.000 inhabitants of multi-ethnic composition, al kind of leisure activities, containing a University, a park, restaurants, bars, pubs and terraces. The district also has residential buildings.   The city has developed new policies that imply to establish the acoustic impact assessments (indoor), no music on terraces and to stop new small bars temporary. This all need to collect more noise monitoring & video surveillance by means of cameras. The devices to examine the noise is an android smartphone and the openoise application (propagation software). The smartphones are calibrated by means of a comparison with a class 1 sound level meter generating pink noise. The developments planned for the future are to install more low-cost sensors (each 5/10 meters), to install also a few class 1 sound meter and provide people with wearable sensors for people and to start research to beam forming. Until now differences are found of about 10 dB the Monday and the weekend days. A small video of the area in Turin can be found here.  By Mr Thomas Montagnon and Christophe Mietlicki,  version 2 of RUMEUR was presented. This global Cloud solution has a back-end open to manage all kinds of noise sensors and GIS data. The front-end is very flexible and can be customized on demand. See The RUMEUR website discloses all kind of distributions (day, day-period, hour, etc.). Also, sound recording can be stored and replayed as historical data and events. By means of RUMEUR, a comparison can be made between different time periods. Bruitparif has partnerships with SNCF (railway noise) and Lille Metropol (traffic noise) and is open for other partnerships. The principle is to pool development costs to add new features.  Then Ms Fanny Mietlicki presented the noise measurements conducted on the right bank of the river Seine. The lower bank was closed for cars over a length of 3 km. By monitoring the noise it was found that around 10 dB reduction occurs due to the closing of the bank on the left side of the bank. However, at the upper bank the noise increased with some dB’s. A lot of NMU’s have been installed (12 permanent, 14 additional and 64 complementary NMU’s). See more at . The last presentation by Bruitparif was done by Mr Christophe Mietlicki. He presented the first results of an experiment on leisure noise. By numerous NMU’s and an acoustic antenna (MEDUSA) the leisure noise can be distinguished from the other noise (e.g. traffic noise). The measurements are carried out in five areas with in total 40 sensors. Measured is dB(A), dB(C) and spectrum with class II devices. The influence of wind is still under research. The MEDUSA used 4 MEMS microphones. The process applied is called triangulations. To prepare the peer review of the sensor systems in Barcelona and in Budapest two brief presentations were given by Ms Julia Camps (Barcelona) and Mr Gabor Céreb (Resono). After the presentations, it was decided to review the Barcelona system in 2017 and the Budapest system in 2018. Information about both systems is provided in the slides which can be found elsewhere on this website.  By Mr Carlos Ribeiro (Bruitparif) the GRAFIC project was presented. This project has already a duration of 4 years, and its aim is to examine the overall pleasantness of the sound environment of an urban and to classify areas of acoustics and perception. Six classes are found. More information (papers on congresses can be found at and also on this website By Professor Mr Dick Botteldooren (UGhent) two new project are briefly presented. The ASA project is trying to collect soundscapes all over the world. Volunteers are invited to join at no costs.  The other project is called Embodied sound monitoring which is a combination of smart lightening and noise measurement devices using the power of light posts.

About 5 members of FONOMOC will participate in ICSV24 in London. If there will be more than it can be considered to organise a FONOMOC meeting alongside this ICSV24 congress. The number of papers already sent is quite poor, now 2 papers are sent in of the 10 abstracts that were uploaded.

At the end of the meeting, the chair thanks everyone for his/her presence and contribution in special the presenters. He also thanked the host, Bruitparif for their hospitality, organising the meeting in an excellent way. Date and venue of the next meeting are to be considered yet. Presentations can be downloaded here.

Report meeting Rome 9 June 2016

This time, the FONOMOC was hosted by ANAS, an Italian government-owned company deputed to the construction and maintenance of Italian motorways and state highways under the control of Italian Ministry of Infrastructure and Transport, being the lead beneficiary of the DYNAMAP project. After welcome by the FONOMOC chair, the approval of the agenda and the

By Ms. Patrizia Bellucci (ANAS) an update of the DYNAMAP project was given. The DYNAMAP project aims to provide a dynamic noise map (à la EU) and to develop the use of a high-quality, low-cost sensor. On the basis of a limited number of sensors, the traffic model and the basic noise map EU, it is made possible to generate a map which moment by moment (5 minutes to 1 hour) represents the varying noise levels. This approach is expected to reduce costs compared to the usual calculations. Added value will be that the map gives almost real-time information to the public and other stakeholders. The system also consists of meteorological stations and can be extended to other applications (e.g. air quality). The project is also working on identifying anomalous noise other than traffic noise (ANED). In due time, this open algorithm will also be available to others. In August 2017 a special session dedicated to DYNAMAP will be held at INTERNOISE Hamburg. All FONOMOC participant are invited to join this session. More information on this project can be obtained at to

photo 21 fonomocA system aimed to identify noise sources was presented by Mr Gabor Geréb of Resono which is a spin-off of University of Technology and Economics Budapest, called source selectivity.  This method aimed to source selective real-time monitoring and mapping of environmental noise, comprising the steps of  identifying sources in the area (1), designing places for the monitoring stations(2), creating a data collecting and data processing centre (3), measuring the noise impact and observation of the sources with the sensors (4); composing the monitoring stations including a sound measuring device (5) and developing a computing unit and a communication unit that determines the resultant noise impact prevailing in the respective measurement points and the dominant noise sources in the individual moments on the basis of the data obtained by the sensors. This identification is based on the characteristics (frequency, time segmentation, etc.) of the sound. Having measured for about 15 hours and using artificial intelligence, it offers a pretty simple measuring system with a relatively inexpensive sensor. There is collaboration with the city of Birmingham (UK).  Gabor is looking for a one-year pilot project. More information can be obtained at Mr Nico Faber (Anteagroup) then presented their Noise monitoring system AAP which stand for Antea Analysis Platform, which is situated near the military airbase Leeuwarden. It is designed to define and recognise the footprint of the F-16 and F-35 (Joint Strike Fighter). In addition to measuring the noise, it also records weather, the sound, and images (by videos footage) if the aircrafts fly over. No comparison is made between the noise maps and the measurements because this noise map is (still) expressed in so-called Kosten units, a Dutch standard. More information about this standard can be found at ( ). Further developments are to apply this system also elsewhere for recognizing other noise source, or using smartphones with annoyance applications and develop ITS applications in cars. Nico looks for cooperation in further developments.  The noise monitoring network RUMEUR that is run by Bruitparif connects numerous terminals and discloses the resulting measurement data. Within the Ile de France region different noise sources in different places (airports, railways, roads and recreational noise) are monitored. The noise data obtained is accessible on one platform and is known as RUMEUR 2.0. It is intended to employ this also elsewhere as a custom made front-end with the aid of templates for each type of application by providing a window information that is desirable. Also, the so called HARMONICA index can be displayed. The partners in the DYNAMAP project are considering to employ the RUMEUR 2.0 front-end. By Mr Enrico Gallo (Torino) the indoor monitoring system that runs in the Mazurri area was presented. This historical is situated along the River Po and is a favourite entertainment area. By conducting noise measurements indoor (e.g., discos, restaurants, dance rooms) and audio recordings enforcement is done. Is it thought to compress the music in order to perceive it louder than it actually is (such as TV advertising). Subsequently, Mr Didier Helal of OrbiWise presented the sensor network of Courage near Geneva. The approach relies heavily on the approach in the telecom world (regarding data transfer) using gateways of telecom providers like Orange, Vodafone, etc. They want to install a thousand sensors (MEMS technology) within the framework of digitization city (smart cities) and IoT (Internet of Things). A base station costs approximately € 1,000 / unit, but could be lower in the future (when series production). After this presentation, Mr Coen Boogerd presented the sensor network of the Maasvlakte which is a part of the Rotterdam industrial and harbour area. Due to many complaints about droning noise from citizens living in the municipality of Westvoorne and previous surveys, it was decided to install a sensor network. The sensors are situated on the Maasvlakte but also in the residential area. Some of these sensors are composed as an array. Citizens are convinced that the droning noise stems from the industry on the Maasvlakte. This noise does not always occur. Previous surveys made clear that meteorological conditions could play a decisive role. Citizens are asked also to log the moments that they notice the droning noise. By analysing the noise data obtained at the moments that noise is noticed the source(s) of the annoyance could be identified and localised. By Ms Itziar Aspuru the CITI-SENSE project from Vitoria-Gasteiz was presented. photo 36 fonomocUsing smartphones with an external microphone and an app in which observations and perceptions can be registered many citizens have been adding information to display the quality of life in their city. Measured is noise, radiation, and temperature. Perceived safety, visual aspects, etc. are also registered and stored in a central database. Also, pictures are added. See also  .The last presentation was given by Jacob Fogola (ARPA Piemonte). This included measurements by smartphones (Android) equipped with a low-cost MEMS microphone (€ 19). The data obtained is sent to a SmartDataNet. Cost per measurement unit (a box) are approximately € 120. The session ‘lessons learned’ was downsized due to the time. Mr Nico Faber gave a summary of the main elements of the FONOMOC meeting. Involving citizens is important (public involvement), open data available for market and public is hot, innovative source localization and identification techniques (ANED, Maasvlakte Resono). Finally, Mr Henk Wolfert presented a brief proposal to apply the peer review system on the noise monitoring networks presented during the FONOMOC meetings. By means of visiting experts/colleagues, the system comes to a critical examination that could lead to proposals for improvement. Due to the time available, this proposal will be further expanded under the FONOMOC members via email. The meeting was attended by 22 people. The next meeting will be held in March 2017 in Paris at Bruitparif and if possible be combined with another event, (e.g. mini congress, a hackathon). All presentations are available here.

On the afternoon of 10 November 2015 a FONOMOC meeting was held in Barcelona. The meeting was held in conjunction with the meeting of the Working Group Noise EUROCITIES. The FONOMOC meeting was attended by 20 persons.
The first presentation was done by Ms Patrizia Belluci (ANAS, which is the national road authority in Italy). The subject of her presentation was DYNAMAP. This LIFE project aims to develop a dynamic map in parts of Rome and Milan. This dynamic noise map represents the noise real time. By the use of low cost sensors and smart algorithm a dynamic noise map can be constructed that saves time and money in comparison with the traditional way of noise mapping (calculation). It is assumed that the savings can be up to 50%. The map will be visualised by means of a GIS platform and is accessible for citizens. The system is also designed that other measuring devices can be connected as well, such as sensors for air quality, meteorology, et cetera. More information about DYNAMAP can be obtained at .

Mr Henk Wolfert and Mr Hans van der Waal (both DCMR EPA) gave an impression of the new sensor network on an industrial area in the Rotterdam Port Area was given. Due to numerous complaints in the past and also currently, this network will be installed. It is expected to run in December 2015. In the past two long term measurements have been executed. It appeared that companies situated on the existing part of the industrial area were meeting their noise limits of the environmental permits. However, sometimes people in the nearest village (Westvoorne) perceived a droning noise that was very annoying. By TNO (Dutch Institute for Applied Sciences) it was suggested that the phenomena of droning noise was due to the meteorological conditions. During measurements in the past no specific source could be localised. That is why the Port Authorities, the Municipality of Westvoorne and the DCMR EPA decided to install a sensor network that has the shape of an array. The measurements will last 1 year and the FONOMOC group will follow the progress of this project and evaluate the outcomes.

By Mr Piot Gaudibert (BruitParif) a presentation was given about the car-free day in Paris. His presentation made clear that there was a drop of noise and a drop in air-pollution during that day. Besides that, now the (main-) roads were free for bikers and pedestrians and that was highly appreciated by these target groups. It could be considered to have more car-free days in the city and also that other cities this event adopt and also introduce car-free days.

By Mr Henk Wolfert a brief report was given about the technical session on sensor networks during the EURONOISE 2015 congress in Maastricht. The papers presented are:

  • Utilising the strengths of different Sound Sensor networks in smart cities (Manvell)
  • Barcelona noise monitoring network (Camps)
  • Sound sensor networks based assessment of traffic, Noise and Air pollution (Dekoninck et al)
  • On the use of linear regression for the assessment of stability in noise monitoring networks (Sotirakopoulos)
  • Real life harmonic source localisation using a network of acoustic vector sensors (Pérez Cabo)
  • Dynamic noise mapping based on fixed and mobile sound measurements (DeCoensel et al)
  • Design and calibration of low cost urban acoustic sensing devices (Mydlarz)
  • Area based environmental noise measurements using wireless sensor networks (Kivelä)

The papers will be sent to the participants who can scrutinise them whether they are interesting and if interesting, the FONOMOC group could invite them to present the sensor network in one of the next meetings. Action: Henk Wolfert. It was also proposed to introduce a so called peer review. By peer reviewing the sensor networks one can learn how to improve the network. The peer review could address the next:

  1. Hardware
  2. Software
  3. Netware (infrastructure)
  4. Dataware
  5. Orgware (organisation, procedures, etc.)
  6. Communication

By Mr Piotr Gaudibert and Henk Wolfert a first proposal will be drafted that can be discussed during the next meeting of FONOMOC. Action: Piotr Gaudibert/Henk Wolfert.

By Ms Julia Camps the Barcelona sensor network was presented. Barcelona has a main network and a secondary network with low costs sensors. The main network exist of class 1 sensors.

By Mr Guillermo de Arcas (university of Madrid) the Recreational Noise Sensor Network of Malaga was presented. This Spanish southern city has a lot of tourists and the tourists and the events to entertain the tourists are causing a lot of noise. the number of inhabitants amounts 300.000 and the number of tourists 1 million.

After the meeting the FONOMOC group visited some smart solutions in Barcelona such as the noise monitoring network, a smart bus stop and smart sensors in the road and containers.

Next meeting will probably held in Rome in conjunction with the DYNAMAP meeting which will be held on 10 June 2016. This means that the FONOMOC meeting will take place on 9 June 2016.



If enough participants are registered the FONOMOC meeting at EURONOISE 2015 Maastricht will be held in conjunction with the congress. Until now (30 April 2015) not enough participants have registered. If interested let us know and send an email to Ms Patricia van Rixoort that you will attend this FONOMOC meeting (


On 23 April the steering committee of DYNAMAP has met in Rome. EUROCITIES WG noise is represented in that steering committee by means of Mr Henk Wolfert. The aim of the DYNAMAP project is to develop a dynamic noise mapping system able to detect and represent in real time the acoustic impact of road infrastructure. The main objective of this project is to ease and reduce the cost of periodically updating noise maps, as required by the European Directive 2002/49/EC on environmental noise. To that end, an automatic monitoring system, based on customised low-cost sensors and a software tool implemented on a general purpose GIS platform, will be developed and built in two pilot areas located along the A90 motorway that surrounds the city of Rome (Italy), and inside the agglomeration of Milan (Italy). A one-year survey will then be undertaken to check the reliability, effectiveness and efficiency of the DYNAMAP system. More information can be obtained at

Second meeting FONOMOC Paris OLD

On the 2oth of May a combined meeting of FONOMOC and HARMONICA project was  be held in Paris. Venue was the office of BruitParif ( 9, impasse Milord, 75018 Paris).  Below an brief impression. The minutes of this meeting can be delivered in a few weeks.


logo bruitparifOn 20 May a successful combined meeting of the Harmonica project
and the FONOMOC Group was held at Bruitparif Paris. HARMONICA project ( aims to deliver a Common Noise Index that makes it easier to communicate with the public and the politicians but also to provide Europe with a website that gives best solutions of reducing noise and last but not least a forum. The FONOMOC is a subgroup of Working Group Noise EUROCITIES aiming to exchange experiences and knowledge on noise monitoring systems among their members, identification of new developments, to contribute in improving existing systems by means of peer reviews and to promote the use of open data, see further elsewhere on this website.

After the welcome, by managing director Ms Fanny Mielicki, a brief pitch was given by the chair of FONOMOC, Mr Henk Wolfert. That pitch gave the objectives of FONOMOC, what already has been achieved and how FONOMOC works. By Prof. Botteldooren of the GlogoHarmonicahent University a presentation was given on sensor networks. It appeared that relative low cost sensors can compete with traditional microphones especially when measuring noise levels that are not very low. The so called noise floor is about 40 dB (A). It was tested by the team of Prof. Botteldooren. He explained how the network ran by UGhent works. Big Data, Internet of Thinks or better Internet of Sounds, neural networks, map based prediction of sleep disturbance and many things more are challenging us. By means of the sensor signal it is also possible to detect whether a sensor is working properly or not. He also referred to the GRAFIC project. Information about this project will follow soon on this blog. By Mr Piotr Gaudibert, Mr Carlos Ribeiro, Mr Bruno Vincent, Ms Fanny, Mr Vincent Gissinger and Mr Christophe Mietlicki the HARMONICA project was illustrated. The Common Noise Index (CNI) was explained, an index based on background noise, events and perception that could help to communicate to the public and the politicians.Not only this CNI will be launched, but also the results of the optimization of the CNI index with an innovative graphical representation, called the Harmonica index. One already can watch a short movie about the harmonica index on the website before being online of the content on the 10th June. The website alsoprovides best solutions to reduce noise and it offers also a forum. The website makes it possible to upload contributions. This could be data collected from measurements but also best solutions that have been or will be employed in cities and regions.

The website will be operational by the 10th of June 2014. Other members of FONOMOC, Working Group Noise or third parties are cordially invited to contribute to this web portal in order to improve the Harmonica index and to collect best solutions. There also a portal will become available to disclose the data from the database (Open Data). By Barcelona (Ms Julia Camps) an overview was given of all the noise monitoring activities in Barcelona. That city is very active and has about 25 noise monitoring units in place. Barcelona uses different microphones or sensors and different configurations. Many activities are monitored like recreational noise, pet noise, traffic noise, et cetera. Most of the data obtained is not published for the public but is hidden ore limited open for the public. Julia noticed that noise hardly is mentioned in the SMART CITIES concept. It was concluded that more promotion of smart noise initiatives is needed towards the smart cities programme.  More information can be obtained at and By Mr Vincent Gissinger a pitch was given about the noise monitoring systems in use in Grand Lyon. The system is running by Acoucité (www.acoucité.org). The system is also installed in Saint Etienne, Grénoble, Nice and Aix en Provence. Mr Gissinger mentioned en passant that Monaco has embraced the HARMONICA noise index.  By Mr Luca Nencinni the noise monitoring system in Pisa was explained. This is a pilot in a small area near the University of Pisa were 25 sensors are installed. The project is called DYNAMAP. The project aims to develop a dynamic noise mapping system that is able to detect and represent in real time the acoustic impact of road infrastructure. This will help implement the European Noise Directive, which requires the updating of noise maps every five years. The project will develop an integrated system for automated data acquisition and processing of road noise. A website is not available yet. By Mr Christophe Mietlicki of Bruitparif the RUMEUR noise monitoring network was presented ( This network is leading in website based communication. Probably the best there is at this moment. It also works with arrays in order to identify noise sources. Since a few weeks radar data of arriving and departing aircrafts is available which makes it easier to address complaints or high noise levels. By Mr Richard Spaans an overview has been given on the Rotterdam/DCMR initiatives. DCMR has a number of noise monitoring units, both permanent and mobile. They are used near the Rotterdam airport (RANOMOS system, which is an acronym for Rotterdam Airport NOise MOnitoring System). It is linked with complaints from citizens and with radar data. It is the most sophisticated system in the Rotterdam Area. Other systems are used to follow trends near railway tracks, industrial areas and in recreational areas. The latter warns the owners of the bars that the noise in the neighbourhood is exceed and the action is needed. By Mr Dick Botteldooren a brief presentation on the so called ears of Katendrecht” was given. This is a participatory project with citizens involved. By means of sensor, connected to Internet, the noise is measured and people can send in their ideas on perception. By means of analysis also noise sources could be localised. No website is available. Residents seemed a bit reluctant in sending in their perceptions. By Turin, which was impeded to join, a brief note was sent in. Turin noise measurements take place on three locations:

  1. city center, main source: public transport tramways and buses
  2. suburb, big road, main source: heavy traffic noise from commute travels
  3. (temporary) suburb, ARPA – Regional Environmental Protection Agency, main source traffic noise. See also the next website:

Concluding it could be noted that:

  •  The noise monitoring network RUMEUR could serve as a best practice to inform the public
  • The CNI and the website is a very good initiative and should be embraced by all European partners in order to improve the CNI and to complete the website’s part with best solutions to reduce noise.
  • Not all presented initiatives provide information to the public by means of a website
  • Traditional Class 1 and Class 2 microphones are being used as well as sensors
  • Sensors are cheaper than traditional class 1 and 2 microphones but to have good results you need more sensors
  • Next meeting will be held alongside the WG Noise meeting in Copenhagen
  • The meeting contributes to improve our noise monitoring systems continuously and inspires all members to make work of innovations.
  • We could seek for opportunities for improvement and innovations by launching EU funded project (LIFE et cetera).


First meeting FONOMOC in Gdansk OLD

The very first meeting of FONOMOC was held in Gdansk (Poland).  The next issues have been decided and exchanged.

The cities of Gdansk, Amsterdam and Rotterdam and also BruitParif are running a noise monitoring system. Turin considers to install a noise monitoring system. After the presentations of Gdansk, Turin, Amsterdam, BruitParif and DCMR EPA we decided the following points.

  1. Henk will disseminate the list with cities that showed interest in FONOMOC
  2. Henk will ask the Air Department of DCMR EPA about the procedures they haven implemented to certify their work (answer: this is accreditation)
  3. Menno will send the url’s of the Schiphol website to all of us and if available the urls’s of the other monitoring websites. (see here)
  4. Jan will provide an English part on the Gdansk website which goes into the noise monitoring. (see here)
  5. Piotr sends the summary of the HARMONICA project which was sent in for subsidy to us in order to take into account making a new proposal for FONOMOC
  6. Piotr will provide us with the url’s of BruitParif (see here)
  7. Priorities of FONOMOC is decided to be road traffic noise, airport noise and railway noise. We will especially pay attention to knowledge experience exchange and validation of calculated noise levels.
  8. We decided to make an application for LIFE+, has to be ready at 18 July at the latest
  9. Bydgoszcz will provide us with the basic idea for a LIFE+ proposal on Noise and we can add other ideas; this could be a different Work Package. Bydgoszcz sends the proposal within 14 days and we will respond within a week.
  10. The basis project idea will be sent to the EUROCITIES office in Brussels in order to make a call for partners.
  11. Besides the possible project FONOMOC will also continue as a subgroup in order to share knowledge and experiences among the cities that showed interest
  12. After or before the meeting of WG Noise in Turin FONOMOC will have a second meeting (as a sub-group) (This was postponed to the Paris meeting, see above)
  13. We have no objections that third parties like universities or suppliers etc.
  14. We should think about a possible lead beneficiary (Universities)

Henk Wolfert is appointed as chairman of FONOMOC.
