In recent years, there has been an increasing interest in the use of acoustic sensors for monitoring urban and environmental noise. The most common concerns are the exposure to high sound levels and the localization of the main noise sources. Pressure-based solutions have been proven useful for observing noise at specific locations, but they have limited capabilities addressing source localization in broad areas, especially transient noises. In contrast, the use of vector sensors combining sound pressure and particle velocity such as the 2D Acoustic-Multi-Mission Sensor (AMMS) or 3D Acoustic Vector Sensors (3D AVS), allows for the determination of the sound direction of arrival at one specific location. The particle velocity sensors integrated in each probe enable a broadband assessment of the entire audible range, providing a quantitative estimation of the loudness and information of the acoustic direction of arrival. Consequently, a set of probes across an area of interest enable the location of noise sources by using triangulation or beamforming upon the acquired data.
