| Models can be used to help visualize new buildings and
new products. Scale models can also help us test certain aspects of
the room or product better than a line drawing on paper or even a
computer model. After testing many different materials, we found that foam-board insulation is hard enough, stiff enough, and reflects sound in a way very similar to drywall. Building a model to one-twelfth scale gives us a large enough model that we can actually test some acoustical aspects of the room. |

| Using a small, self-amplified test speaker (that we
already tested the frequency response of) and our standard measurement
mic, we test the model. (Yes, it's important to put the roof on!) In the photos below you can see a series of tests we completed testing diffusion of different types (Periodical Diffusers, and High-Pass diffusers). The last photo shows testing balloons and the diffusive effect they have on mid and high frequencies! We expect to post our measurement results in the near future. |
