0.001 ml is the lowest detectable volume change
Initial latency = 35 ms (5 ms)
Rise time = 45 ms (5 ms)
Terminal latency = 35 ms (5 ms)
Fall time = 45 ms (5 ms)
Overshoot = max. 1%
Undershoot = max 1%
Values between -600 to +300 daPa can be selected in the

The actual sound pressure level at the eardrum will depend
on the volume of the ear. See Table 2 for details.
