Abstract IEC 60268-16:2011(E) specifies objective methods for rating the transmission quality of speech with respect to intelligibility. It provides a comprehensive manual for all types of users of the STI method in the fields of audio, communications and acoustics. Three methods are presented, which are closely related and are referred to as STI, STIPA, and STITEL. The first two methods are intended for rating speech transmission performance with or without sound systems. The STITEL method has more restricted uses. This fourth edition cancels and replaces the third edition, published in 2003, and constitutes a technical revision. This edition includes the following significant technical changes with respect to the previous edition: development of more comprehensive, complete and unambiguous standardization of the STI methodology; the term STIr is discontinued. A new function for the prediction of auditory masking effects is introduced; the concept of 'speech level' and the setting of the level of the test signal have been introduced; additional information has been included on prediction and measurement procedures.
