The Brüel & Kjær Sentinel platform is a real-time Environmental Compliance Monitoring software solution. One of the key uses of the Sentinel software is in urban noise monitoring. Urban noise environments are complex, consisting of multiple sound sources, that can often disrupt the desired data logging. For example, cars and trucks driving past a construction site can falsely increase average loudness levels, resulting in false violations of noise regulations. Localising the sound and providing a visualisation of the noise source's location can provide the user with better insight to the accuracy of noise readings. The current noise monitors deployed in Sentinel systems use omnidirectional microphones, and do not have any method for identifying where the noise violations has come from in relation to the monitor. The alternative systems that offer directional noise monitoring require expensive hardware, and are often to costly for the intended use. The aim of this project is to find an alternative approach that allows for localisation of noise sources using the existing hardware deployed in Sentinel systems.
