New SONICOM research introduces BezierPPM – a new parametric model of the pinna based on cubic Bézier curves and concave deformations. This parametric pinna model (PPM) represents the biological structure of the human pinna and enables its parametric modelling in many degrees of freedom.
“In contrast to other PPMs, BezierPPM is based on the biological structure of the human pinna aiming at providing parameters directly related to the complex pinna geometry,” says Felix Perfler, PhD student at the Acoustics Research Institute of the Austrian Academy of Sciences and first author of the publication. “Our analysis shows that BezierPPM can accurately represent human pinnae, meaning that it has high potential for a range of applications, including biometric identification, the design of ear prostheses, and the personalisation of spatial hearing."
