论文摘要
最佳点可以解释为声学源产生空间听觉幻觉的地区。我们研究了使用一系列扬声器再现所需的声波时最大化这个最佳位置的问题。为了实现这一目标，我们引入了一个空间声音感知的理论框架，该框架可用于定义最佳位置，并且我们开发了一种旨在产生声波的方法，该方法旨在直接在此框架内直接最大化模型定义的甜点。我们的方法旨在纳入一开始的感知原理，并且是灵活的：尽管它对感兴趣的区域，扬声器的排列或其辐射模式几乎没有任何约束，但它允许有音频感知模型，其中包括最先进的单声感知模型。概念验证实验表明，我们的方法在其本地化和着色属性方面比较了最先进的方法。
The sweet spot can be interpreted as the region where acoustic sources create a spatial auditory illusion. We study the problem of maximizing this sweet spot when reproducing a desired sound wave using an array of loudspeakers. To achieve this, we introduce a theoretical framework for spatial sound perception that can be used to define a sweet spot, and we develop a method that aims to generate a sound wave that directly maximizes the sweet spot defined by a model within this framework. Our method aims to incorporate perceptual principles from the onset and is flexible: while it imposes little to no constraints on the regions of interest, the arrangement of loudspeakers or their radiation pattern, it allows for audio perception models that include state-of-the-art monaural perceptual models. Proof-of-concept experiments show that our method outperforms state-of-the-art methods when comparing them in terms of their localization and coloration properties.
