Head and Torso HRTF Computation

Application ID: 75011

This tutorial model shows how to import a 3D scanned geometry of a human head and torso and compute the head related transfer function (HRTF). The scan is imported as a .stl file and converted into a COMSOL geometry. The HRTF is computed using the reciprocity principle, locating the source at the ear canal entrance, and the acoustics are simulated using the Pressure Acoustics, Boundary Element interface. The simulated results are compared to measured data form the actual subject and show good agreement.

The scanned geometry and measured data is with courtesy of the Teaching and Research Area of Medical Acoustics, Institute of Technical Acoustics, RWTH Aachen University, Germany.

This model example illustrates applications of this type that would nominally be built using the following products:
