FFT Acoustic analysis
S-1-3 Octave analysis of noise from OA equipments and home appliances
- The 1/1 and 1/3 real time octave analysis is useful for reducing noise from OA equipments, and home appliances such as air conditioners or printer. In this example, four microphones are set at bystander position surrounding the measurement object to obtain the noise. It also can be set A, C or Z-weighting sound filter for a microphone. And, measured signal by the microphones are input to the DS-5000 O-Solution to perform octave analysis. Then you can see the accurate noise data numerically with various display functions, such as data comparison between before and after noise countermeasure, 3D display or trend display (time series variation) of specified frequency band. Up to 64ch-system also can be assembled.
