GSO IEC 60268-16:2014 音频系统设备 第16部分：通过语音传输质量测量指南客观评估语音清晰度

This part of IEC 60268 specifies objective methods for rating the transmission quality of speech with respect to intelligibility. The objective of this standard is to provide a comprehensive manual for all types of users of the STI method in the fields of audio, communications and acoustics. This standard does not provide STI criteria for certification of transmission channels (e.g. criteria for a voice-alarm system). 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. NOTE None of the methods are suitable for the measurement and assessment of speech privacy and speech masking systems, as STI has not been validated for conditions that represent speech privacy applications [1]1. The following information is included: • measurement techniques; • prediction techniques.

This part of IEC 61606 is applicable to the basic methods of measurement of the audio characteristics of the digital audio part of audio and audiovisual equipment for all of consumer use, professional use and personal computer. The common measuring conditions and methods, described in this standard, are used for the measurement of the performance characteristics of equipment having an audio bandwidth equal to approximately one-half of the sampling frequency of a system, where the audio information is processed in the form of digital data. CD players, DAT recorders, digital amplifiers, digital sound broadcast receivers and television broadcast receivers with digital sound are examples. This standard describes test methods for equipment which has digital input with analogue output and analogue input with digital output. Future revisions of this standard will cover digital-in/digital-out and analogue-in/analogue-out tests. This standard does not apply to a lossy compression signal and also does not apply to power amplifiers. NOTE 1 A digital audio system having an analogue input and an analogue output with digital signal processing may have different characteristics from those of a pure analogue audio system due to sampling of the audio signal and performance of incorporated A/D and D/A converters. Measurement methods described in IEC 60268-3 may not give correct results when applied to a digital system. NOTE 2 The methods described are mostly based on sampling frequencies of 32 kHz and higher. NOTE 3 For tests of those systems of digital-in – digital-out, and analogue-in – analogue-out tests, refer to AES17. NOTE 4 This standard is planned to harmonize with the first edition of IEC 61606 (1997)1, AES17 and EIAJ CP- 2i50.

When used for other purposes, the interface is able to carry audio data coded other than as linear PCM coded audio samples. Provision is also made to allow the interface to carry data related to computer software or signals coded using non-linear PCM. The format specification for these applications is not part of this standard. The interface is intended for operation at audio sampling frequencies of 32kHz and above. Auxiliary information is transmitted along with the programme.
