The last decade has shown a growing number and wide variety of systems for monitoring environmental noise. This ongoing development is made possible by the availability of cheaper and smaller hardware and innovations in communication networks. The developments are fed by a growing interest in monitoring because it can help in improving noise maps and in getting more insight in complex noise situations. It can also help to take appropriate and cost efficient measures and to assess the effect of these measures. Furthermore, it is a welcome instrument for communication and policy making. In this paper several developments and approaches for acoustic sensor networks are discussed with examples from literature. The systems vary from application of expensive dedicated hardware to low cost sensor nodes and networks based on smartphones. While each system has its own advantages and disadvantages, the various approaches will be compared with respect to several aspects such as costs, scalability, flexibility, reliability and accuracy. One of the considered systems is the acoustic sensor network developed by TNO. This system is based on two types of low cost acoustic sensor nodes, a basic sensor node and an advanced sensor node, in a scalable architecture. The specific benefits of this system will be discussed in more detail. This includes recent developments such as automatic classification and accurate synchronization, which were successfully applied in a field test using seven advanced nodes and twenty-eight basic nodes for monitoring traffic noise in a complex situation |
