The SPL (Sound Pressure Level) heat map shows how sound distributes across your room. Think of it like a weather map, but for sound intensity instead of temperature.

Good vs. Bad Heat Maps

LR
✓ Uniform coverage
Even distribution = ideal
LR
✗ Hot spots & cold spots
Uneven = poor placement

Hot Spots (Red Areas Near Walls)

Red zones near walls mean sound is reflecting and building up. This causes some areas to sound unnaturally loud.

💡 Fix: Add acoustic panels, bookshelves, or soft furnishings near hot spots to absorb excess reflections.

Cold Spots (Blue Areas)

Blue zones are areas that don't receive enough sound energy. People sitting here will struggle to hear clearly.

💡 Fix: Reposition speakers toward cold spots, or consider adding another speaker for better coverage.

Why Uniform Coverage Matters

The best listening experience comes from even sound coverage. If you see a smooth, consistent color across your seating area, your speakers are well-placed. Big color differences mean some listeners will hear too much bass or treble while others hear too little.
