A common problem that arises during modal testing is the inability to directly excite degrees-of-freedom to obtain frequency response functions (FRFs). It has been shown previously that reliable reproduction of FRFs via indirect excitation is difficu... Read More about Operational measurement of frequency response functions.

Prediction of Radiated Structural Noise Using Decomposed Vibro-Acoustic Frequency Response Functions (2024)
Journal Article

The manner in which a system radiates noise is dependent upon the resonant behaviour and the forced vibration of the structure. It has been shown previously that the modes of such a system can be identified by performing a singular value decompositio...
