Response time (F,S, I)
Selectable time response settings used in SoundPro SE/DL measurements. The response
time is a standardized exponential time weighting of the input signal according to fast (F),
slow (S) or impulse (I) time response relationships. Time response can be described with a
time constant. The time constants for fast, slow and impulse responses are 0.125 s, 1.0 s and
35 ms, respectively. Impulse time response is 35ms rise with a constant decay of 2.9dB/sec.
