Bisschop, M.C. Contributor Hendriks, R.C. (mentor) Khademi, S.

This project is a part of a three-group bachelor graduation project of six peoplein total. The three groups combined create a working game for visually impaired children, meant to be used to train the user’s ears and brain to visualize their surroundings using sound only. Using the mirror source method, a model for sound reflections in concave 3D rooms is obtained. Important parts of this model are the placement of the mirror sources, the calculation of a line of sight and a model for the energy absorption of a wall when sound is reflected off of it. The placement of mirror sources and a model for the wall absorption were successfully implemented. The calculation of a line of sight is only half finished.The implementation of the model in the game adds a sense of the location and the materials of the walls.The execution time of the model is however too low to run the model completely in real time.
