Understand the inputs
See how room size, surface area and frequency-dependent absorption contribute to the estimate.
Acouso Playground
Free acoustic calculators and room acoustics tools.
Explore RT60, materials, and room geometry with free interactive tools. Start with a six-band reverberation-time calculator using Sabine or Norris–Eyring.

Start with room reverberation.
The Playground will grow into a collection of focused acoustic calculations and visual explanations. Each tool is designed to make the assumptions visible, not hide them behind a result.

Free Reverberation Time Calculator
Build a simple room, assign six-band absorption materials, compare RT60 before and after treatment, and switch between Sabine and Norris–Eyring.
- Six octave bands
- Editable materials
- Treatment comparison
- Interactive 3D room
Compare a design move
Add a treatment area and review the before-and-after response without rebuilding the room.
Move into the model
Use Acouso-ROOM when the calculation needs to stay connected to rooms, materials and results in Revit.
Learn the acoustics
Understand the methods behind the result.
The calculator keeps the workflow concise. These Learn guides go deeper into RT60, the two equations, and more detailed room-acoustic modelling.
Acouso-ROOM
Take acoustic analysis into your Revit model.
The Playground helps explain an individual calculation. Acouso-ROOM connects acoustic analysis to the rooms and materials across your project.
