Figure 3. Mean SNR values and regression lines for individual formants at the different distances.

Figure 3

The regression slope values quantify how the formant amplitudes of re-recorded bellows drop over distance (N = 10). Higher regression slope values indicate greater amplitude attenuation over distance.
