Optimize the acoustics of your space in just a few clicks.
Step 1 : Enter the dimensions of the room
Step 2 : Enter the room finishes
Step 3 : Select the desired Reverberation Time (RT60)
To determine the recommended RT60 for your space, please refer to the table below, which presents suggested values according to the type of environment and its use.
Step 4 : Choose the thickness of your panel
Choose a 1-inch thick acoustic panel to primarily absorb high frequencies and speech-related frequencies in spaces with low to moderate noise levels.
Choose a 2-inch thick acoustic panel for noisier or more reverberant spaces in order to achieve better sound absorption, including lower frequencies.

Table of Recommended RT60 Values by Space Type
General reference
RT60 (reverberation time) represents the time it takes for sound to decay by 60 dB in a room. A properly adjusted RT60 improves acoustic comfort, speech intelligibility, and the overall atmosphere of spaces.
Quick interpretation
Low RT60 → better speech intelligibility and improved concentration.
Medium RT60 → balanced and comfortable atmosphere.
High RT60 → livelier, more reverberant space, often used for music or large architectural volumes.
