摘    要:随着计算机科学的发展,声学的可听化技术被越来越广泛地应用到主观实验研究中.声学软件ODEON可以建立很好的仿真声场,利用ODEON的可听化技术,对矩形高大空间和狭长空间的语言清晰度进行实验研究.结果表明,对于同一空间中的不同接收点的语言清晰度,早期衰变时间的影响比信噪比的影响显著;在语言清晰度为主要设计指标的厅堂中,应该主要控制早期衰变时间,使其不能超过1.5 s.

关 键 词:早期衰变时间  信噪比  语言清晰度  声学软件

Abstract:As the development of computer technology,auralization method is widely conducted in subjective experiment.ODEON,an acoustic software which can simulate the sound field nicely,was used as a tool to compare the speech intelligibility between large-volume space and long space.The results indicate that in the same space the early-decay-time performs more prominently than signal-noise-ratio.As a result,the early-decay-time is proposed to be designed as the main parameter and be less than 1.5 seconds in rooms where the main target is to obtain a high speech intelligibility.
Keywords:early-decay-time   signal-noise-ratio   speech-intelligibility   acoustic software
