Structural vibrations excited by pressure loading which is random in space and time are considered. Power spectra of generalized force and generalized coordinate variables are discussed in general linear vibrating systems. Vibration magnitude of generalized coordinate variables and mode shapes are determined from simultaneous measurement of vibration quantities at many points by summing up the results with variable weightings. As an example, flexural vibration of thin beam, which is acted upon by pressure fluctuation of air flow or random sound pressure, is measured by strain gages and real time spectrum analyzer.
