Loudspeaker Array Simulator

I needed to simulate speaker array configurations before building them. So I built a browser-based tool that does exactly that.

The simulator has been useful for planning column speakers and bass arrays. Instead of guessing, you can see how different configurations actually behave - spacing, curvature, attenuation patterns, the lot.

What It Calculates

For each frequency and measurement position, the tool sums complex amplitudes from all speakers:

• Inverse square law - SPL drop with distance
• Phase relationships - Path length differences at each frequency
• Speaker directivity - Baffled piston model with Bessel functions

Real speakers become more directional at higher frequencies. The simulator models this, so you see the high-frequency narrowing that happens in real arrays.

What You’ll See

Comb filtering at off-axis angles. How curvature affects coverage. High-frequency narrowing with directivity enabled. How attenuation patterns reduce side lobes.

Limitations

This is for building intuition, not replacing professional acoustic modeling software. No room modes, no air absorption, simplified reflections.

Good enough to validate ideas before spending money.
