The vocal tract organ is a new musical instrument that consists of three-dimensional (3D)-printed vocal tracts (throat and mouth) for individual vowels sitting on loudspeakers to enable static vowel sounds to be produced.
The acoustic excitation from the loudspeakers is a synthesized version of the typical waveform produced by the vibrating human vocal folds during pitched sounds, which enables the instrument to be played from a keyboard.
The vocal tract organ will become an instrument in its own right, and it could be used as a direct replacement for the vox humana organ stop, given that its acoustic output is a much closer representation of the human vocal output than that from a vox humana organ pipe. The 3D-printed tracts may also be used in vocal and choral workshops as well as degree-level music technology education.
This according to “The vocal tract organ and the vox humana organ stop” by David M. Howard (Journal of music, technology & education VII/3  pp. 265–277).
Above, an illustration from the article; below, a composition by Professor Howard.
In an experiment, direct high-speed video observations of an elephant larynx demonstrated flow-induced self-sustained vocal fold vibration in the absence of any neural signals, thus excluding the need for any purring mechanism. The observed physical principles of voice production apply to a wide variety of mammals, extending across a remarkably large range of fundamental frequencies and body sizes, spanning more than five orders of magnitude.
This according to “How low can you go? Physical production mechanism of elephant infrasonic vocalizations” by Christian T. Herbst, et al. (Science CCCXXXVII/6094 [3 August 2012] pp. 595–599). Below, a podcast interview with Dr. Herbst provides examples and further details (including the fact that the elephant had died of natural causes).
