In the POP Force DOP, second set of parms where the noise is added, enable the Use VEX Expressions.

There is a preset down arrow menu button to the right of the editor window. There you will find a few presets. Try the “Amplitude By Age” option which puts down this:

// Ease in using age in seconds
amp *= smooth(0, 1.5, @age);

The smooth(min,max,variable) expression reads like:
The smooth function returns a value of 0 if the variable is less than the min value, an ease curve going from 0-1 for the variable between the min and max values, and returns 1 when the variable is greater than the max value.

So adjust the 0 and 1.5 to control when the 0-1 ease curve starts and ends.
There's at least one school like the old school!
