Noise Source Identification (NSI) is an important method for optimizing the noise emission from a wide range of products from vehicles, white goods, power tools and heavy machinery to components like engines, tyres, gear‐boxes, exhausts, etc. The goal of NSI is to identify the most important sub‐sources on an object in terms of position, frequency content and sound power radiation. Ranking of sub‐sources can be used to identify where design changes will most effectively improve the overall noise radiation. Spherical Beamforming Type 8606: provides a 360° soundfield map without making assumptions about the sound field.
