19. MG-102S, Tokkyokiki Corporation. The vibration noise spectra were recorded with a data-logger (RS-1, Tokkyokiki Corporation). Sampling rate: 256 Hz, window function: hanning, and averaging process: peak-hold. The spectrum was averaged over 400 lines.
20. Sampling rate: 256 Hz, window function: hanning, and averaging process: peak-hold. The spectrum was averaged over 400 lines.
21. When the active vibration isolation dampers were turned off, the honeycomb bench was rested on the active vibration isolation system.
22. The transfer function H(f) is described as follows: H(f) (B(f) A(f))(A(f) A(f)), where f, A(f), B(f), A(f), and B(f) is frequency, Fourier spectrum of input signal, Fourier spectrum of output signal, conjugate of A(f), and conjugate of B(f), respectively.
23. Sampling rate: 256 Hz, window function: hanning, and averaging process: peak-hold. The spectrum was averaged over 400 lines.
24. yy is cross-spectrum between input and output signals, power-spectrum of the input signal, and power-spectrum of the output signal, respectively.
