NSI - Intensity Mapping

Noise Source Identification (NSI) is an important method for optimising the noise emission from a wide range of mechanical and electro-mechanical products like vehicle engines, components , aircrafts, appliances, power tools, industrial machinery, etc.

In addition, selective intensity may be used to further identify the internal root sources and radiation mechanisms involved. Since intensity mapping typically involve measuring a large number of points, the measurement is most effectively performed using an automated microphone positioning system (robot).
