When we examine a countermeasure against noise in a large-scale factory, it is necessary to investigate sound sources supposed comparatively influential in detail, and to calculate noise propagation condition repeatedly, using a complex computer simulation .
When a factory has a large amount of complex noise sources, there is tremendous amount of work needed to take a detailed measurement. Moreover, a vast amount of time will also, have to be spent on performing an acoustical simulation in-house.
However, using the omni-directional sound source analyzing system called 'Noise Vision' which has the potential of separating the entire noise, it can diagnose the condition of the noise source easily.
By using this noise diagnostic result, it is easy to verify the important point and priority of countermeasure against factory noise. Depending on factory's scale, for example, when we carry out measurement using 'Noise vision' for 2 days, it is possible to turn in the report attached the following result of the analysis in the evening of the 2nd day.
