Exemplary results using subglottal impedance-based inverse filtering of a weeklong neck-surface acceleration signal from an adult female with a normal voice. Histograms of the maximum flow declination rate (MFDR) measure are displayed in physical and logarithmic units. The logarithm of MFDR is plotted against sound pressure level (SPL) to confirm the expected linear correlation (r = 0.94) and slope (1.13 dB/dB).
