大量最近的研究已经检查了在基于Web的实验中视觉呈现的刺激的呈现持续时间和响应时间测量的准确性，一般的结论是，大多数种类的实验的准确性是可以接受的。然而，行为研究的许多领域使用听觉刺激代替视觉刺激，或者除了视觉刺激之外。使用标准的基于网络的测试程序对听觉准确性的了解要少得多。我们使用毫秒精度的黑盒工具包来测量听觉刺激的实际持续时间以及听觉和视觉呈现开始的同步。我们研究了100个听觉和视觉刺激的演示文稿在两台不同规格的计算机上的时间分布，三种常用的浏览器，以及用Adobe Flash或JavaScript编写的代码。我们还研究了不同的编码选项，试图同步的听觉和视觉发作。总的来说，我们发现听觉持续时间非常一致，但视觉和听觉开始之间的滞后在浏览器和计算机系统中差异很大。本文的在线版本（doi：10.3758/s13428-016-0758-5）包含补充材料，可供授权用户使用。
Substantial recent research has examined the accuracy of presentation durations and response time measurements for visually presented stimuli in Web-based experiments, with a general conclusion that accuracy is acceptable for most kinds of experiments. However, many areas of behavioral research use auditory stimuli instead of, or in addition to, visual stimuli. Much less is known about auditory accuracy using standard Web-based testing procedures. We used a millisecond-accurate Black Box Toolkit to measure the actual durations of auditory stimuli and the synchronization of auditory and visual presentation onsets. We examined the distribution of timings for 100 presentations of auditory and visual stimuli across two computers with difference specs, three commonly used browsers, and code written in either Adobe Flash or JavaScript. We also examined different coding options for attempting to synchronize the auditory and visual onsets. Overall, we found that auditory durations were very consistent, but that the lags between visual and auditory onsets varied substantially across browsers and computer systems.
