Speech Intelligibility

STI-PA setup

Post Process	An optional “captured curve” feature can be applied to your STI-PA
	testing. Essentially, you take a snap shot of the current sound level
field
	measurement and store it as your background noise. Once the
	background noise data is gathered, you can apply the captured
	noise during your STI-PA measurement. This may be used in a
	situation where you cannot play the test signal during “normal”
	working hours. (Please refer to Chapter 1, “When to take STI-PA
	measurements, scenario 2” for more details.)
Range field	You can change the range when measuring. The following ranges
	are selectable parameters: 90 dB – 140 dB, 80 dB – 130 dB, 70 dB
	-120 dB ,60 dB – 110 dB, 50 dB – 100 dB, 40 dB – 90 dB, 30 dB- 80
	dB, and 20 dB – 70 dB.
