Speech Intelligibility Option for XL2 Analyzer
The STI-PA function measures the speech intelligibility of public announcement systems according the latest revision of IEC 60268-16:2003 standard. The XL2 displays the measurement results as STI or as CIS results, accompanied by the individual levels and modulation indices of the seven octave bands. The measurement results are acquired from the dedicated STI-PA test signal, generated by the included STI-PA Test CD.
