几十年来，人们一直在研究房间声学质量的测量和技术描述。早期的研究只处理单点测量和估计语音和音乐演示的质量参数，使用简单的模型，如早到晚到达的声音能量比。最近的研究还考虑了声场的空间特征，并开发和研究了各种参数。音乐厅声学的两个最突出的特征是视源宽度（ASW）和听众包络度（LEV）。ASW描述的是声音场景的感知宽度，而LEV与被声音包围的感觉有关。然而，ASW和LEV的作用在科学界仍在讨论中。本文研究了在虚拟声环境（VAE）中利用波场合成（WFS）进行声音再现的ASW和LEV。在不同的虚拟房间中，通过使用多个紧密间隔的虚拟声源来模拟声源的宽度。在共29名听者的听力测试中，评估了感知参数ASW和LEV。
For several decades the measurement and technical description of the acoustical quality of a room is under investigation. Early research only dealt with single point measurements and estimated quality parameters for speech and music presentations by using simple models, like the early to late arriving sound energy ratio. Recent research also takes the spatial characteristics of a sound field into account, and a variety of parameters have been developed and investigated. The two most prominent features in concert hall acoustics are the apparent source width (ASW) and the listener envelopment (LEV). ASW describes the perceived width of the sound scene, while LEV is associated with the feeling of being enveloped by sound. However the role of ASW and LEV is still under discussion in the scientific community. In this paper ASW and LEV are investigated in the context of virtual acoustic environments (VAE) using wave field synthesis (WFS) for sound reproduction. The width of the sound source is modeled in different virtual rooms by using multiple closely spaced virtual sound sources. The perceptual parameters ASW and LEV are evaluated in listening tests with a total of 29 listeners.
