Introduction to Reverberation Time (Sabine Formula)

The Sabine Formula for Reverberation Time is a widely used equation in acoustics to estimate the reverberation time within a space. The formula calculates the time taken for sound to decay by 60 decibels after the sound source ceases. In this formula, RT₆₀ represents the reverberation time, V is the volume of the space, and A is the total absorption of the space.

Parameter usage:


Data validation

The volume must be a positive number (greater than zero), and the absorption must be a non-negative number.


This formula helps in estimating the acoustic properties of a space based on its volume and total absorption, providing valuable insight for architectural and acoustic engineering design.
