Figure 4 From: Classification of human breathing sounds by the common vampire bat, Desmodus rotundus Vampire hearing and breathing-sound spectra. Absolute auditory thresholds averaged across three individuals of D. rotundus are shown as symbols and the fine line; error bars represent standard errors of the mean. Averaged breathing-sound magnitude spectra are shown by the strong black line; the strong grey lines again represent standard errors. This comparisons show that in D. rotundus, auditory sensitivity is well suited to detecting and analyzing breathing sounds.Back to article page
