In order to evaluate the acoustic performance of a newly designed engine block under various operating conditions, prototypes of different designs can be built, and acoustic parameters, such as sound pressure level, acoustic intensity, and radiated sound power, can be measured at various operating conditions.
CSI also helps identify deficiencies in process and machine design through modal analysis, which determines vibration modes; acoustic intensity testing, which identifies noise problems; and performs product quality testing and general troubleshooting.
These products are well-suited for rotating machinery, such as engines, where speed varies with time; o I-DEAS Acoustic Intensity Measurement software assists users in noise source identification by collecting real-time acoustic data, as well as calculating and displaying acoustic intensities.
