Enter your Room Length, Width, and Height alongside Room Type, Wall Material, Floor Material, and Ceiling Material — the Room Acoustics Calculator figures out your RT60 Reverberation Time, Room Volume, Total Surface Area, and Mean Free Path so you know how sound behaves in your space.

RT60 is the time it takes for sound to decay by 60 decibels after the source stops. It's the standard measurement for room acoustics, with optimal times varying by room type and use.
Home theaters: 0.3-0.5 seconds, recording studios: 0.2-0.4 seconds, listening rooms: 0.4-0.6 seconds, conference rooms: 0.6-0.8 seconds. The calculator provides recommendations based on your room type.
Minimum coverage (15-20% of wall area) provides basic acoustic improvement, while recommended coverage (25-35%) offers significantly better performance. Start with minimum and add more as needed.
Minimum coverage addresses basic echo and reverberation issues. Recommended coverage provides professional-level acoustic control with better speech clarity and reduced room coloration.
For most rooms, focus on walls first, especially the front wall and first reflection points. Ceiling treatment becomes important in rooms with hard surfaces or when maximum acoustic control is needed.
Larger rooms typically need proportionally less coverage as a percentage of surface area, but more total material. Smaller rooms often benefit from more aggressive treatment due to closer boundaries.
This calculator works best for rectangular rooms. For irregular shapes, calculate the equivalent rectangular dimensions or break the space into rectangular sections and calculate separately.
