And here is a more sophisticated 2D version of the Wall Bounce Calculator. It simulates reflections from both the front and side walls of a rectangular room.

Check out that scary initial layout I plugged in!

A 3D version is in the works!:D

Thanks a lot for the 2D version, very interesting and educational

Now, what about the 3D version ?

So is this frequency curve supposed to represent your room prior to any acoustic treatment? Surely if you put up reflection absorbers or diffusers that would change the frequency response at the listening position?

And what about variables such as ceiling height and wall material (ie would a wall of clay not produce a different response than a wall of glass?)

Im not being pendantic or critical here rather just trying to understand the application of this very interesting little spreadsheet. So if this graph was to tell you that there was a large bump at 1200 hz, would the obvious conclusion be to tune your room with a graphic EQ, making a dip at 1200 hz? How do you correct discrepancies of particular frequencies?

Thanks a lot

I don't quite understand the use here, should I be plug in in my room size? And if so then which fields?
Thanks! Looks like a cool and useful tool.

This is actually giving me a lot of hope =) seems I didn't screw up my placement too much, the graph actually looks really decent I hope the results will be similar to my "end product"

Cheers
