One direct applications of the techniques
developped during my PhD is room acoustics simulations. Given a 3D model
of a room and the acoustic properties of the surfaces, we can calculate
at any location the room 'response'.
This response is a digital filter that encodes all sound modifications as it propagates from the source to the receiver. From this filter we can reproduce the sound as if it was heard in the room (auralization process) or calculate several quality criterias in order to evaluate the room acoustics. These criteria can then be visualized in order to help the designers improving the room acoustic quality.
