Room Acoustics Calculator & 3D Visualizer

Transform your listening environment with our advanced Room Acoustics Calculator. Designed for audio engineers, audiophiles, and spatial planners, this tool goes beyond simple measurements by analyzing your specific dimensions to calculate precise RT60 reverb times and identify problematic low-frequency room modes (standing waves). Featuring a real-time 3D Room Visualizer, it applies the Sabine formula to provide actionable data, helping you control bass response, improve speech intelligibility, and determine the optimal strategy for acoustic panel placement in studios, control rooms, and workspaces.

Complex Room or Specific Needs?

This calculator is optimized for standard rectangular spaces. For L-shaped rooms, non-rectangular rooms or spaces with vaulted ceilings, let our engineers build a custom plan for you.

SBX sub: tuning by air gap

The SBX sub features a suspended membrane for targeted bass control. Placing it close to the wall tunes it to ~75Hz, while increasing the air gap shifts absorption deeper. Hover over the bar to see the effective target frequency.
