Calculate the reverberation time of a room using either Sabine’s or Eyring’s formula by entering the required details in the calculator.
Reverberation Time Calculation Formula
The following formulas are used to calculate the reverberation time of a room.
Sabine: RT = (0.161 * Volume) / Absorption Area
Eyring: RT = (0.161 * Volume) / (-Volume * ln(1 - Absorption Coefficient))
Variables:
- RT is the reverberation time (s)
- Volume is the room volume (m³)
- Absorption Area is the total absorption area (m²) for Sabine
- Absorption Coefficient is the average absorption coefficient for Eyring
To calculate the reverberation time, use the appropriate formula and input the required values. The reverberation time is a critical factor in room acoustics, impacting how sound behaves in a space.
What is Reverberation Time?
Reverberation time is the measure of how long it takes for sound to decay by 60 dB in a closed space. It is an essential parameter in acoustics, affecting speech intelligibility, music quality, and overall acoustic comfort. Properly managing reverberation time is crucial for various environments such as concert halls, classrooms, and recording studios.
How to Calculate Reverberation Time?
The following steps outline how to calculate the reverberation time using the given formulas.
- Determine the room volume and either the absorption area or the average absorption coefficient.
- Choose the appropriate formula (Sabine or Eyring).
- Plug in the values: Sabine: RT = (0.161 * Volume) / Absorption Area, Eyring: RT = (0.161 * Volume)
