房间声学参数是音频特征，通常从房间声学环境的单声道或双耳测量中提取，并用于预测“房间声学印象”的不同方面。本文需要仔细研究这种感知结构的性质，并在不同的方法来开发一个心理测量仪器的多维感知档案的房间声学环境。即使经过几十年的研究，也没有令人满意的解决方案可用于此目的。其原因在于测试开发和项目分析方面的方法缺陷，以及在以前的研究中使用的刺激样本太小。先进的室内声学模拟和可听化技术开辟了进步的前景，这些技术可用于提供大量具有代表性的室内声学环境样本，并在实验研究中提供真实的演示。由这种方法提供的基本感知组件将，最有可能的是，传统的房间声学参数是不可预测的，但需要先进的测量技术的基础上的球形阵列的换能器的源和接收器的特性，以及新的听觉模型的特征提取。无论如何，这一问题的生理和心理方面是相互联系的。
Room acoustical parameters are audio features, usually extracted from monaural or binaural measurements of room acoustical environments, and used to predict different aspects of the ‘room acoustical impression’. The paper takes a closer look at the nature of this perceptional construct and at different approaches to develop a psychological measuring instrument for the multidimensional perceptional profile of room acoustical environments. Even after several decades of research, there is no satisfactory solution available for this purpose. The reasons for this lie in methodological deficits with respect to test development and item analysis as well as in a much too small sample of stimuli used in previous studies. Prospects for progress are opened up by state-of-the-art technologies for room acoustical simulation and auralization, which may be used to provide a large and representative sample of room acoustical environments as well as an authentic presentation in experimental studies. The fundamental perceptional components delivered by this approach will, most likely, not be predictable by traditional room acoustical parameters, but require advanced measurement techniques based on spherical arrays of transducers for both source and receiver characteristics, as well as new auditory models for feature extraction. The physical and psychological aspects of the problem are, in any case, inextricably linked with each other.
