van der Eerden, F.J.M. (author), Brouns, E. (author), Eisses, A.R. (author), van Vliet, W. (author)By using elements with quarter-wavelength resonators of different depths alongside a road, noise can be diffracted upwards to create a zone of noise reduction behind these elements. Measurements at a short distance, up to 15 meters, have proven that a noise reduction up to 4 dB(A) can be achieved. The noise reduction at long distance, up to 600...conference paper 2019

van der Eerden, F.J.M. (author), van den Berg, F.H.A. (author), Wessels, P.W. (author), Kruyen, A.H.J. (author)The use of combining sound measurements and sound propagation modelling is increasing. In this paper the acoustic situation on and around a shooting range is considered. A monitoring system that automatically detects and localizes impulsive sound events is presented. The locations of these events are obtained by combining detections from...conference paper 2018

(author)A long-term monitoring project, with 12 months of continuous operation time, is described where the sound sources within a large industrial area as well as the sound levels in the nearby residential area are measured. The sources in the industrial area may give rise to complaints from the neighboring residential areas, at several kilometers...conference paper 2017

(author)Source localization using microphone arrays has now become common practice for many applications. Their application for long term monitoring of industrial noise nevertheless remains uncommon. Hence, in 2016 we deployed four microphone arrays near a large industrial area for a period of 12 months and explored the challenges involved. The...conference paper 2017

van der Eerden, F.J.M. (author), Binnerts, B. (author), Graafland, F. (author)Noise control starts by understanding the actual noise situation. Especially for situations where the distance between industrial and traffic noise sources and a local community is in the order of one kilometer or more, it may not be clear what sources are the main contributors to annoyance. Then a combination of monitoring and modeling is...conference paper 2015

Wessels, P.W. (author), Basten, T.G.H. (author), van der Eerden, F.J.M. (author), Graafland, F. (author)Developments in systems for monitoring environmental noise have made it possible to monitor the acoustic situation within large urban areas. The developments in hardware size and costs, combined with the developments in wireless communication allow to deploy networks with many acoustic sensors without much effort. An application of such a sensor...conference paper 2014

van der Eerden, F.J.M. (author), Graafland, F. (author), Wessels, P.W. (author), Basten, T.G.H. (author)A model based monitoring system is applied on a local scale in an urban area to obtain a better understanding of the traffic noise situation. The system consists of a scalable sensor network and an engineering model. A better understanding is needed to take appropriate and cost efficient measures, especially when changes to the local...conference paper 2013

Nijhof, M.J.J. (author), van der Eerden, F.J.M. (author)National legislation enforces a limit on the Sound Levels of outdoor military shooting ranges observed in nearby residential areas. These restrictions directly influence the number of shots that may be fired at a specific shooting range, which may conflict with the required/ scheduled training capacity for that specific range. If desired, sound...conference paper 2013

van der Eerden, F.J.M. (author), Lutgendorf, D. (author), Wessels, P.W. (author), Basten, T.G.H. (author)Urban traffic noise can be a major issue for people and (local) governments. On a local scale the use of measurements is increasing, especially when measures or changes to the local infrastructure are proposed. However, measuring (only) urban traffic noise is a challenging task. By using a model based monitoring system, consisting of a scalable...conference paper 2012

van der Eerden, F.J.M. (author), van den Berg, F.H.A. (author)Environmental research is ongoing to predict and to mitigate the noise impact of heavy weapons or explosives. In the densely populated area of the Netherlands this is of particular interest for the Ministry of Defence as the shock waves can propagate over large distances. In this research program the mitigation of shock waves by means of a sound...article 2012

Wessels, P.W. (author), Basten, T.G.H. (author), van der Eerden, F.J.M. (author)A good understanding of the acoustic environment due to traffic in urban areas is very important and can be obtained by long term model based monitoring within large areas. As a result one has a good basis for assessing the effect of mitigating measures and for communication and policy making. A monitoring approach has been developed, based on...conference paper 2012

Bosschaart, C. (author), Eisses, A.R. (author), van der Eerden, F.J.M. (author)Ground noise due to aircraft starting from the Amsterdam airport runway ‘Polderbaan’ has been an issue since its construction in 2003. Take off operation in headwind conditions causes downwind sound propagation towards a residential area situated 2,5 km Southwest of the runway. Due to the large propagation distance, the wind- and ground...conference paper 2012

(author)This paper deals with the first stages of the development of a new test method for evaluating the reflectivity performance of noise barriers. The reflectivity performance describes the increase in sound level at a receiver due to the presence of the noise barrier. First the current test method for sound reflectivity is simulated with three...conference paper 2011

Wessels, P.W. (author), Basten, T.G.H. (author), van der Eerden, F.J.M. (author)In order to have a good understanding of the environmental acoustic effects of traffic it is important to perform long term monitoring within large areas. With traditional monitoring approaches this is quite unfeasible and the costs are relatively high. Within TNO a new wireless monitoring approach has been developed which is based on low cost...conference paper 2011
