Sound system equipment - Part 16: Objective rating of speech intelligibility by speech transmission index

IEC 60268-16:2011 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. It 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. The French version of this standard has not been voted upon.

Elektroakustische Geräte - Teil 16: Objektive Bewertung der Sprachverständlichkeit durch den Sprachübertragungsindex

Equipements pour systèmes électroacoustiques - Partie 16: Evaluation objective de l'intelligibilité de la parole au moyen de l'indice de transmission de la parole

La CEI 60268-16:2011 spécifie des méthodes objectives d'évaluation de la qualité de transmission de la parole sous l'angle de l'intelligibilité. Elle met un manuel complet à la disposition de tous les types d'utilisateurs de la méthode STI dans les domaines de l'audio, des communications et de l'acoustique. Trois méthodes, étroitement liées, sont présentées sous le nom de STI, STIPA, et STITEL. Les deux premières méthodes sont destinées à l'évaluation des performances de la transmission de la parole avec ou sans systèmes électroacoustiques. La méthode STITEL a des utilisations plus restreintes. Cette quatrième édition annule et remplace la troisième édition parue en 2003, et constitue une révision technique. Elle inclut les modifications techniques importantes suivantes par rapport à l'édition précédente: - Le développement d'une normalisation plus aboutie, plus complète et moins ambiguë de la méthodologie STI; - le terme STIr n'est plus utilisé. Une nouvelle fonction pour la prédiction des effets du masquage auditif est introduite; - le concept de "niveau de parole" et le réglage du niveau du signal d'essai ont été introduits; - des informations supplémentaires relatives aux modes opératoires de prédiction et de mesures ont été incluses. La version française de cette norme n'a pas été soumise au vote.

Oprema za zvokovne sisteme - 16. del: Objektivno ocenjevanje govorne razumljivosti z uporabo indeksa prenosa govora (IEC 60268-16:2011)

Ta del IEC 60268 določa objektivne metode za ocenjevanje kakovosti prenosa govora z zvezi z razumljivostjo.
Cilj tega standarda je zagotoviti celosten priročnik za vse vrste uporabnikov
metode STI pri slušnosti komunikaciji in akustiki.
Ta standard ne zagotavlja kriterijev STI za certifikacijo kanalov prenosa (npr. kriterijev za sistem glas-alarm).
Predstavljene so tri metode, ki so tesno povezane in so omenjene kot STI, STIPA in STITEL. Prvi dve metodi sta namenjeni ocenjevanju delovanja prenosa govora
z zvokovnimi sistemi ali brez njih.
Uporabe metode STITEL so bolj omejene.
OPOMBA: Nobena izmed teh metod ni primerna za merjenje in ocenitev zasebnosti govora in sistemov za maskiranje govora, ker STI ni bil potrjen za zahteve, ki predstavljajo uporabe za zasebnost govora [1]1.
Vključene so naslednje informacije:
• tehnike merjenja;
• tehnike napovedovanja.
