Influence of the artificial torso of the dummy head
The localization ability of humans stem from the influence by the head and pinna shape on the sound field. To recreate such an influence, it is often more efficient to have a fixed head model. These models, or artificial heads give a good but not individually perfect spatial impression of sound sources. This thesis focuses on the influence of the torso of an artificial head that is used both as a reference measurement device and an important tool for many virtual acoustics scenarios. It is studied with the use of Boundary Element Method simulation which will allow an easy way to examine different types of material as well as different geometries. The goal of the thesis is to create a simulation that is similar to measurements with a wooden torso while gaining a better understanding of the importance of the torso to the head.
