CEI - EN IEC 60268-16

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

active, Most Current
Organization: CEI
Publication Date: 1 June 2021
Status: active
Page Count: 136
ICS Code (Audio, video and audiovisual systems in general): 33.160.01
scope:

This part of IEC 60268 defines the STI model, test signals, measurement and prediction methods.

The objective of this document is to provide a comprehensive manual for all types of users of the STI model in the fields of audio, communications and acoustics.

This document does not provide STI criteria for certification of transmission channels (e.g. criteria for a voice-alarm system), but some typical application values are provided in Annex G.

Every measurement method has limitations, and the reader is referred to clauses relating to limitations such as speech privacy, echo and systems using digital voice compression (vocoders).

This document does not cover the case of fluctuating noise on the STI, although some general comments on dealing with this complex issue are provided in 7.13 and 8.9.3.
