GB/T 15485-1995
AbolishedAcoustics--Methods for the calculation of the articulation index of speech
声学 语言清晰度指数的计算方法
Application Summary AI generated
This standard specifies calculation methods for the articulation index of speech, which quantifies speech intelligibility in a given acoustic environment. It is applied in acoustical engineering and product testing contexts, such as evaluating the performance of communication systems, public address systems, and room acoustics in auditoriums or telecommunication devices. The standard is used by engineers to predict and measure how clearly speech is understood under specified noise and reverberation conditions.
