  Animations

The animations below show visualisation of scattered sound field simulated with two different acoustic models:

  • The animations with the blue background were all simulated with an analytical model of a rigid sphere. These demonstrate time domain propagation of the spherical waves, first for a free field model and a single monopole source, and later with two loudspeakers which their inputs were filtered to produced the desired signals.

  • The next set of animations include both time and frequency domain simulations that used numerical methods together with accurate mesh models of KEMAR.


More information is given on each animation page. (best viewed with a monitor resolution of 1027x768 pixels)
