    Linked via "Sabine units"

    $T_{60}$ is the reverberation time in seconds, defined as the time required for the sound pressure level to decrease by 60 dB from an initial steady state.
    $V$ is the volume of the room in cubic meters ($\text{m}^3$).
    $A$ is the total effective absorption of the room surfaces and contents, measured in Sabine units (or metric Sabins), calculated as the sum of the product of each surface area ($S_i$) and its [absorpti…
