Acoustics calculator
For most commonly found shapes and materials generally used, you can calculate the reverberation time in a room with our acoustics calculator. The reverberation time should correspond to the recommended values that are based on the intended use of the space. We do need to acknowledge the importance of these calculations; however, they are only one of the aspects of an otherwise complex process of acoustic design - we gladly offer our expertise in helping with the latter.
The acoustics calculator on this webpage determines the reverberation time in octave bands using Sabine and Eyring’s equations, two of the most commonly used options for calculating the reverberation time. The data on the absorption coefficients of materials is taken from expert literature, and the calculation takes into account air attenuation in circumstances of 50% air humidity.
Using the calculator in three simple steps
1) Determine the shape and dimensions of the room; the surface area of the outer surfaces and the volume of the room will be calculated.
2) Determine the type of material of individual surfaces. If there is more than one material used, you can add it.
3) The reverberation time is then calculated automatically. Choose the intended use of the room above the graph, and you will see whether or not your room is acoustically appropriate. You can download the graph by clicking the button PRINT.
