Acoustics - Reverberation Time (Sabine Formula)
Formula:RT₆₀ = 0.161 * (V / A)
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:
V= volume of the space (cubic meters)A= total absorption of the space (sabins)
Output:
RT₆₀= reverberation time in seconds
Data validation
The volume must be a positive number (greater than zero), and the absorption must be a non-negative number.
Summary
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.
