About Reverb Time Calculator (Formula)

Acoustic design plays a crucial role in creating spaces with optimal sound quality and clarity. One of the key parameters in acoustic design is the reverb time, often referred to as the “reverberation time” or “RT60.” Reverb time is the time it takes for a sound to decay by 60 decibels (dB) after the sound source has stopped. It is an essential factor to consider when designing spaces for various purposes, such as concert halls, recording studios, or even residential rooms.

The Reverb Time Formula

Reverb time (T) can be calculated using a simple formula:

�=0.1611⋅��T=A0.1611⋅V​

Where:

• $T$ is the reverb time in seconds (s).
• $V$ is the volume of the room in cubic meters (m³).
• $A$ is the total absorption in sabins (sab).

Understanding the components of this formula is crucial for achieving the desired acoustic characteristics in a space.

Volume (V): The volume of a room is a fundamental factor in reverb time calculation. Larger rooms tend to have longer reverb times, as sound waves take more time to bounce around before dissipating. In contrast, smaller rooms typically have shorter reverb times.

Absorption (A): Absorption refers to the ability of materials and surfaces within a room to absorb sound energy. Different materials have different absorption coefficients, which are measured in sabins. Highly absorbent materials, such as acoustic panels, curtains, and carpets, can reduce reverb time significantly. On the other hand, reflective surfaces like glass or concrete can increase reverb time.

Reverb Time Calculator

To simplify the process of calculating reverb time, we’ve created a Reverb Time Calculator that allows you to input the room’s volume (V) and the total absorption (A) in sabins. The calculator will then provide you with the reverb time (T) in seconds.
