Room Boundary Simulator
Version: 1.01 (2019-08-21)
Software platform: Windows
Simulation of early reflections from the floor, ceiling and from the wall behind the speaker.
- Following room reflections are simulated: first-order reflections from the floor, ceiling and the rear wall and second-order reflections from the rear wall (upper and lower corners).
- The driver is modelled by a set of point sources (no cone 'break-up').
- Baffle step and rear response are estimated from the baffle width.
What is this software good for? For example, you can create a setup and change only one parameter (as a variable) at a time and see the effect of that parameter.
Usually the deep notches caused by the floor and ceiling are not present in the room response of a speaker, because the diffuse (random) reflections from the walls fill the large gaps and smooth the frequency response. (There is an estimation for the diffuse room response by setting the absorption coefficient of the floor and ceiling to 0.5.)
Important notice: This simulation does not substitute in-room measurements.

Changes in version 1.01.:
- Improved baffle step and rear response (better agreement with measurements when the speaker is close to the rear wall).
