System determines amount of radiated sound power separately attributed to airborne and structure-borne paths in aircraft. Also used to evaluate vibrating plates and thin shells. Sound transducers include array of lightweight, miniature piezoelectric accelerometers and two-microphone probe. Multichannel Fast Fourier Transform (FFT) analyzer/computer used for analog-to-digital conversion and to analyze spectrum of each of input signals. Noise-path identification in aircraft performed in flight by this system.
