The formula to calculate the Reverb Decay Time (RT60) is:
\[ RT60 = 0.1611 \cdot \frac{V}{A \cdot S} \]
Where:
Reverb Decay, also known as reverberation time or RT60, refers to the time it takes for the sound to decay by 60 decibels after the source of the sound has stopped. It is a measure of the persistence of sound in a particular space after the original sound is removed. This is a key factor in the perceived ambiance of a space and is often used in audio production and room acoustics to create or simulate different environments.
Let's say the volume of the room (V) is 100 cubic meters, the absorption coefficient (A) is 0.5, and the total surface area of the room (S) is 200 square meters. Using the formula:
\[ RT60 = 0.1611 \cdot \frac{100}{0.5 \cdot 200} \approx 0.1611 \text{ seconds} \]
So, the Reverb Decay Time (RT60) is approximately 0.1611 seconds.
