Recent research carried out at Surrey's Institute of Sound Recording has developed software that can predict the perceived room width and the location and width of sound sources from audio recordings made using microphones positioned in the ears of a listener or a dummy head. This software is useful in the development of sound reproduction systems such as home cinema systems, because it is cheaper, quicker and more accurate than asking a large number of listeners to judge the sound. However, we now need to investigate the best way to apply this software to making measurements of these sound reproduction systems.Humans make great use of head movement to work out where sounds are coming from. This helps to sort out a number of issues, including whether the sound source is in front or behind, and whether the sound source is above or below. Taking this into account, if our measurements are to accurately predict what we hear when we listen to a surround sound system, we need to find out: what type of head movements we make; how best to capture the signals at the ears to take into account these head movements; and what it sounds like when various physical parameters change as we move our heads. By finding answers to all these questions, we can develop a measurement technique that captures the ear signals in a manner that is relevant to the way in which we usually listen, and we can properly interpret the results from the software.

萨里大学录音研究所（Surrey’s Institute of Sound Recording）最近进行的一项研究开发了一种软件，可以通过放置在听众耳朵或假头上的麦克风录制的音频，预测感知到的房间宽度以及声源的位置和宽度。该软件在诸如家庭影院系统等声音再现系统的开发中很有用，因为它比要求大量听众判断声音更便宜、更快、更准确。然而，我们现在需要研究应用该软件对这些声音再现系统进行测量的最佳方法。人类经常利用头部运动来判断声音的来源。这有助于整理一些问题，包括声源是在前面还是后面，以及声源是在上面还是下面。考虑到这一点，如果我们的测量要准确地预测我们在听环绕声系统时听到的声音，我们需要弄清楚：我们做了什么类型的头部运动；如何最好地捕捉耳朵的信号，以考虑这些头部运动；以及当我们移动头部时，各种物理参数发生变化时的声音。通过找到所有这些问题的答案，我们可以开发一种测量技术，以一种与我们通常倾听的方式相关的方式捕获耳朵信号，并且我们可以正确地解释软件的结果。
