SC044

This is a curve with a medium fast decay at Start and a very slow decay at the End. The area of the curve is 40.4% of the full square area (-7.89 dB FSA).

If based on area ratio (current to Linear (50%), it’s RT60 time should be 0.81 of Linear RT60.

This curve was calculated from the Semicubical Parabola Curve Equation, applying a value of 0.444444 as constant.
