STIPA
Averaging of STI Results
The standard IEC 60268-16 recommends averaging two or
three subsequent results taken at the same measurement lo-
cation.
The German Standard VDE 0833-4 requires performing mini-
mum three subsequent measurements for one measurement
position in case of STI < 0.63.
The XL2 Analyzer offers automated averaging of two up to
eight speech intelligibility results based on these standard re-
quirements.
