Development of a dynamic loudness model including perceptual weights

响度是声音的感知强度，是听觉的一个重要方面。它在评估环境噪声时起着至关重要的作用。若干标准描述了响度感知的某些方面。这些都建立在响度模型的基础上，这些模型是基于相对简单的声音的听觉实验。然而，对于某些环境声音，观察到感知和预测之间的巨大差异，特别是对于具有强时间波动的声音。这种差异的原因可能是这些方法中不包括响度感知的所有方面。听觉实验表明，听众对声音的不同部分赋予不同的权重。例如，声音的初始部分对于响度比稍后的时间点更重要。目前还不清楚声源在空间中的位置（例如，在听众前面或从上方）对响度有影响。该项目的第一个目的是更好地了解在评估声音响度时人类如何分配权重。第二个目标是在现有数据以及项目中将收集的数据的基础上开发新的响度模型。与现有的响度模型相比，该新模型在计算其响度时将包括声音的不同分量的特定加权。

Loudness is the perceived intensity of a sound and is an important aspect of hearing. It plays a crucial role when assessing environmental noise. Several standards describe certain aspects of loudness perception. These build on loudness models which are based on hearing experiments with comparatively simple sounds. However, for some environmental sounds, large difference between perception and prediction are observed, especially for sound with strong temporal fluctuations. A reason for this discrepancy may be that not all aspects of loudness perception are included in these approaches. Hearing experiments showed that listeners assign different weights to different portions of the sound. For example, the initial portion of a sound is more important for loudness than later points in time. At present it is unclear if the position of the sound source in space (e.g., in front of the listener or from above) has an impact on loudness. The first aim of the project is to gain a better understanding of how weights are assigned by humans when evaluating the loudness of a sound. The second aim is to develop a new loudness model on the basis of existing data as well as on the data that will be collected in the project. In contrast to present loudness models, this new model will include a specific weighting of different components of the sound when calculating its loudness.
