Where should I start with acoustic treatment?

Start with bass traps in all corners (they have the biggest impact). Next, treat first reflection points on side walls and ceiling. Then add absorption panels to remaining wall areas. Finally, add diffusion to the rear wall.

What RT60 should I aim for?

Mixing rooms: 0.25-0.35s. Recording rooms: 0.3-0.5s. Podcast booths: 0.2-0.3s. Practice rooms: 0.4-0.6s. Lower RT60 means a drier, more controlled sound. Very low values (<0.2s) can sound unnaturally dead.

How thick should absorption panels be?

Thicker panels absorb lower frequencies. 50 mm panels are effective down to ~500 Hz. 100 mm panels reach ~250 Hz. For broadband absorption, use 100 mm panels or mount 50 mm panels with an air gap behind them.

Diffusers scatter sound energy rather than absorbing it, maintaining a sense of space while controlling reflections. They are most useful on the rear wall of mixing rooms. For small rooms (<15 m²), focus on absorption first — diffusion needs distance to work effectively.

How We Calculate This

RT60 = 0.161 × room volume / total absorption (Sabine equation)

The calculator estimates the untreated RT60 from room dimensions, then calculates how much additional absorption is needed to reach the target RT60 for your room use.

Panel coverage is based on the budget level: minimal (25% of walls), moderate (40%), or comprehensive (55%).

Bass traps are placed in room corners where low-frequency energy accumulates. The number depends on budget level.
