HRTF Rattle

HRTF Rattle

The HRTF Rattle is an example of the Sonic Interaction Design of a Metaphor for Physical Sonification, which extends on the earlier  HRTF Bells. The rattle is constructed from both left and right ear HRTFs so that the sound is influenced by the complete HRTF dataset.

Here is how it sounds when you shake it.

The HRTF data was measured from a Kemar dummy head, but future versions will be constructed from individual HRTFs of human subjects. Will the rattles made from different people sound distinctly different ? Can this physical sonification be used to classify or analyse these datasets ? Stay tuned….
