From: Syringeal vocal folds do not have a voice in zebra finch vocal development
Mechanical efficiency is not affected by respiratory pressure, but is lower on the right side of adult zebra finch. (a) Example of one pb-ramp (from top to bottom) received sound pressure, bronchial and interclavicular air sac pressures, acoustic and aerodynamic power and mechanical efficiency (ME). (b) Mechanical efficiency in the pressure control space for the left hemi-syrinx of an adult male zebra finch (100 DPH). (c,d) Mechanical efficiency was significantly higher for the left hemi-syrinx than the right hemi-syrinx in both sexes. For statistics see Supplementary Table S1. *p < 0.05.
