Exploring the effect of the occurrence of sound on force applied by the ear when listening at a surface.

In this article, we explore the effect of the occurrence of a target sound on the force that is applied by the ear when listening at a surface because differences in applied force induce variation in carprints of a single ear. Forty two subjects each listened four times at a surface. During two of these listening efforts there was silence.

Exploratory study on classification and individualisation of earprints.

The FearID research project is aimed at the individualisation of earprints for the purpose of forensic research. The study presented here was carried out within the framework of this project. It intends to combine a review of what is known from literature on the classification and individualisation of earprints with results from a preliminary study of earprints.
