What the Room Acoustic Simulator does
Enter a room size, place speakers and subwoofers on a to-scale top-down plan, set each one’s aim and mount height, and see a broadband SPL heatmap with per-speaker coverage footprints and a plain-language coverage verdict. It carries verified specifications for 163 professional speaker models across 11 brands.
How the estimate is calculated
Each speaker’s maximum SPL at one metre is attenuated by the inverse-square law over the 3D distance to each floor point at ear height, reduced by an off-axis roll-off derived from the coverage angle, then energy-summed across all placed speakers. This is a free-field estimate: it does not model room reflections, reverberation time, room modes, air absorption or per-frequency behaviour.
How this differs from EASE Focus
Engineering-grade acoustic simulation (EASE Focus 3 / AFMG) uses measured per-frequency directivity data (GLL files) and models reflections and air absorption. This tool is a fast first-pass coverage estimate; for a final design, use EASE Focus 3 or send the brief.
Room Acoustic Simulator — SPL heatmap and coverage footprints
Free-field broadband estimate — not a measured acoustic simulation. Reflections, room modes and per-frequency behaviour are not modelled. For engineering-grade results use EASE Focus 3 or send the brief.
