Power spectra of the waveforms shown in Fig. 14. Bandstop filters were further applied at 2000 and 4000 Hz. \(\bigtriangleup\), \(\bigtriangledown\), and \(\bigcirc\), indicate the peaks which we identified as air column resonances (\(n = 0\), 1) and Helmholtz resonance, respectively. \(\bigtriangleup\) and \(\bigtriangledown\) plotted on the upper frequency axis indicate the \(f_{\mathrm{A}}\) calculated from Eq. (20) using \(n = 0, 1\) and their sizes correspond to L
