Log 30 Gold

This is a curve with a slow decay at Start and a fast decay at the End. The area of the curve is 39.85% of the full square area (-7.99 dB FSA).

If based on area ratio (current to Linear (50%), it’s RT60 time should be 0.8 of Linear RT60. time

This curve was calculated by inserting the number FI in a base 30 logarithmic equation.
