Synthetic click parameters for EE1, EE2, and EE3.
<p>Synthetic click parameters for EE1, EE2, and EE3.</p
Frequency dependent directivity diagrams.
<p>Top row: Azimuth frequency-dependent directivity diagrams for EE mouth-clicks at 40cm. Lines indicate average of measured data; shaded regions denote 1 SD around the average; different colours denote different frequency bands. Middle row: Azimuth frequency-dependent directivity diagrams for EE mouth-clicks at 100cm. Line and colour coding as in top row. Bottom row: Elevation frequency-dependent directivity diagrams for EE mouth-clicks. Line and colour coding as in top row.</p
Frequency content of clicks for all echolocators.
<p>Top: Averaged spectrograms; Middle: Averaged power spectral density (PSD) plots; shaded regions denote 1 SD around the average; Bottom: Waterfall plots showing a set of PSD estimates for a subset of clicks and the average PSD estimate (black line at back).</p
Directivity diagrams.
<p>Top row: Azimuth directivity diagrams for EE mouth-clicks at 40cm. Markers indicate average of measured data; shaded regions denote 1 SD around the average; red line is fit of a modified cardioid. Middle row: Azimuth directivity diagrams for EE mouth-clicks at 100cm. Symbol and colour coding as in top row. Bottom row: Elevation directivity diagrams for EE mouth-clicks. Markers indicate average of measured data; shaded regions denote 1 SD around the average.</p
Illustrations of click waveforms.
<p>Illustrations of waveforms of three clicks for each of the three echolocators.</p
Click synthesis.
<p>Synthetic clicks plotted for EE1 (left), EE2 (middle), and EE3 (right) in the frequency-time-domain (top), frequency-domain (middle), and time-domain (bottom).</p
Directivity diagrams.
<p>Azimuth dependent directivity diagrams for speech based on [<a href="http://www.ploscompbiol.org/article/info:doi/10.1371/journal.pcbi.1005670#pcbi.1005670.ref020" target="_blank">20</a>] (magenta) and [<a href="http://www.ploscompbiol.org/article/info:doi/10.1371/journal.pcbi.1005670#pcbi.1005670.ref021" target="_blank">21</a>] (cyan) and for clicks from EE1-EE3 (red lines and blue symbols; plotted as in <a href="http://www.ploscompbiol.org/article/info:doi/10.1371/journal.pcbi.1005670#pcbi.1005670.g003" target="_blank">Fig 3</a>). All measurements from 100cm.</p
Time domain envelope.
<p>Figures show envelope estimate for three EE1 Clicks, along with the mean squared error (MSE) of the estimate.</p
