We present a sonification method which we call Focused Audification (FA; previously: Augmented Audification) that allows to expand pure audification in a flexible way. It is based on a combination of single-side-band modulation and a pitch modulation of the original data stream. Based on two free parameters, the sonification’s frequency range is adjustable to the human hearing range and allows to interactively zoom into the data set at any scale. The parameters have been adjusted in a multimodal experiment on cardiac data by laypeople. Following from these results we suggest a procedure for parameter optimization to achieve an optimal listening range for any data set, adjusted to human speech.

重点审核及其参数优化

我们提出了一种称为集中式听觉化（FA；以前称为：增强式听觉化）的声音处理方法，该方法可以灵活地扩展纯音质。它基于单边带调制和原始数据流的音高调制的组合。基于两个自由参数，超声波的频率范围可调整到人类的听觉范围，并允许以任意比例交互式放大数据集。外行对心脏数据进行的多模式实验已对参数进行了调整。根据这些结果，我们建议进行参数优化的过程，以实现针对任何调整为人类语音的数据集的最佳收听范围。
