Abstract :
This paper presents the combination of acoustic diffusers with a mode-stirred chamber to enhance the field homogeneity. Simulations with a TLM-based time-domain computer program show a more homogenous field in this advanced mode-stirred chamber lined with diffusers on the walls compared to a rectangular reference room, a room with Schroeder diffusers and a normal mode-stirred chamber. An optimized paddle in the mode-stirred chamber will improve the results further
