FAQ – Acoustic Calculator
How do I calculate the number of acoustic panels needed?
The acoustic calculator estimates the required treatment surface (sq. ft.) based on the dimensions, finishes, and intended use of your room. It then divides this value by the surface area of each panel (rectangular, circular, hexagonal, 3D, or cube) to determine the exact number of panels to install.
What types of acoustic panels can I calculate with this tool?
Our calculator takes into account several formats:
- Rectangular and square panels (e.g., 12"x47", 23"x23", 47"x47")
- Circular panels (DX24", DX36", DX47")
- Hexagonal panels (Hex24"x21", Hex47"x40")
- 3D panels and cubes
Each size is factored in to provide an accurate estimate.
In what types of spaces can I use the acoustic calculator?
The tool is suitable for many environments:
- Offices and meeting rooms
- Recording and broadcasting studios
- Restaurants and cafeterias
- Classrooms and training centers
- Churches, multipurpose halls, gyms, and performance venues
Is the calculator free to use?
Yes ✅. The acoustic calculator is completely free and available online. It gives you an instant estimate and can help you plan your acoustic treatment projects.
