The omnidirectional system analysis sources from NAE - Nittobo Acoustic Engineering - Tokyo - Japan
 
 
This system consists of a spherical transducer equipped with 31 microphones and 12 cameras, and allows you to get, as a result of a rapid and simple acquisition, the noise map in any direction with respect to ball-transducer. The representation of noise maps can be both static form for the analysis of phenomena stationary, both in form 'animated' for the analysis of the phenomena of non-stationary or moving source.

The rapid identification of different sources within a complex machinery that help with the total noise emitted by a machine, as well as the search for sources within a workplace, has always been a problem primary importance, which for its solution requires usually lengthy and complex acoustic measurements. With Noise Vision is possible to obtain the same results (and more) in a form of immediate interpretation and execution time of measurement and processing of extremely modest.
