The XL2 Analyzer, with the STIPA Option installed, measures the speech intelligibility according to the latest revision of standard IEC 60268-16:2011 (edition 4) and older editions. It offers ambient noise correction and automated averaging for repeated measurements. The XL2 displays the speech transmission index (STI) and the common intelligibility scale (CIS), accompanied by the individual levels and modulation indices of the seven octave bands.

The measurement results are acquired from the dedicated STIPA test signal source:

NTi Audio TalkBox
Acoustic signal generator, required for audio systems with voice microphones, thus measuring the complete signal chain.

Minirator MR-PRO

Test signal generator, required for audio systems with line inputs

STIPA Test CD

STI reporting tool

STIPA Reporting Tool

The STI Reporting Tool creates measurement reports according to the IEC 60268-16 and VDE0833 standards. The tool calculates the effect of the actual ambient noise caused by the public onto the measured speech intelligibility. Thus it provides you the expected speech intelligibility in STI or CIS during real-life emergency announcements.

The STI Reporting Tool is free to download at the XL2 Support website.
