在交互式虚拟声学环境中，总系统延迟（TSL）对于模拟的真实性起着重要作用，无论是纯声学[1]还是视听模拟[2]。关于仅可检测延迟的阈值的知识将允许渲染工作的适当调整。此外，将确定可用于附加音频处理的净空。以往的研究大多采用基于无回声头相关传递函数（HRTF）的可听化方法来研究潜伏期。因此，由于混响声学环境的双耳模拟不存在可靠的阈值，因此本研究针对不同的声学环境进行，并且在无标准自适应心理声学过程中使用不同的刺激。
In an interactive virtual acoustic environment the total system latency (TSL) plays an important role for the authenticity of simulations, be it a purely acoustic [1] or an audiovisual simulation [2]. Knowledge about thresholds of just detectable latency will allow for adequate adjustment of the rendering effort. Moreover, headroom available for additional audio processing will be determined. Most former studies examined latency by means of auralization based on anechoic head related transfer functions (HRTFs). Thus, as no reliable thresholds exist for the binaural simulation of reverberant acoustic environments this study was conducted for different acoustic environments, and using different stimuli in a criterion free adaptive psychoacoustic procedure.
