Delvaux, Bertrand and Howard, David Martin orcid.org/0000-0001-9516-9551 (2014) A new method to explore the spectral impact of the piriform fossae on the singing voice:Benchmarking using MRI-based 3D-printed vocal tracts. PLoS ONE. e102680. ISSN 1932-6203
Abstract
The piriform fossae are the 2 pear-shaped cavities lateral to the laryngeal vestibule at the lower end of the vocal tract. They act acoustically as side-branches to the main tract, resulting in a spectral zero in the output of the human voice. This study investigates their spectral role by comparing numerical and experimental results of MRI-based 3D printed Vocal Tracts, for which a new experimental method (based on room acoustics) is introduced. The findings support results in the literature: the piriform fossae create a spectral trough in the region 4–5 kHz and act as formants repellents. Moreover, this study extends those results by demonstrating numerically and perceptually the impact of having large piriform fossae on the sung output.
