Stipa Pro - Vox -01 Operating Manual

STIPA pro

The STIPA pro module is also used to measure the Speech Transmission Index, but unlike the
quick STIPA module, it also comprises features that allow you to analyze and manipulate your
measurement data in greater detail.
"STI and spectrum" and "measurement details" screen in the STIPA pro module
The STIPA pro module has five screens:
STI and spectrum : display measured STI, octave spectrum and dBA level
Measurement details: display all measurement details including the MTF
Settings : configure the STIPA pro module
Additive noise: enter and enable/disable a noise spectrum to add to data
Browse measurements: review saved measurements
Measurements are usually started from the "STI and spectrum" or the "measurement
details" screen. STI measurements are set up and started in the same way as when using the
Quick STIPA module (see above). However, in the STIPA pro module, more details about
the measurement are shown, and the user has more elaborate options to configure the
measurement. Measurements are started, stopped and saved in the same way as with the
Quick STIPA module (by using the buttons at the bottom of the screen).
The "STI and spectrum" screen shows not only the current STI value and the A-weighted
sound pressure level, but it also shows an octave band spectrum of the measured signal in
the 7 octave bands from 125 Hz to 8 kHz. The STI analysis is carried out in these octave
bands. The scale of the octave band spectrum plot can be modified by tapping on the
triangualar arrows to the left of the plot.
