The current Micro-Electro-Mechanical System (MEMS) technology allows to deploy relatively low-cost Wireless Sensor Networks (WSN) composed of MEMS microphone arrays for accurate sound-source localization. However, the evaluation and the selection of the most accurate and power-efficient network's topology is not trivial when considering dynamic MEMS microphone arrays. Despite software simulators are usually considered, they are high-computational intensive tasks which require hours to days to be completed. Our demonstrator is an FPGA-based network emulator, which provides a fast network design-space exploration. The user can easily evaluate a network's topology with different nodes' configurations and multiple sound sources in matter of seconds. An intuitive graphical user interface hides from the user the dynamic partial reconfigurations needed by the network emulator to set the node's configurations. As a result, a probability map generated from the fusion of the output data from the nodes and an error on the estimation of the sound-source location are graphically represented.
