Auditory interfaces, such as auditory alarms, are useful tools for human computer interaction. Unfortunately, poor detectability and annoyance inhibit the efficacy of many interface sounds. Here, it is shown in two ways how moving beyond the traditional simplistic temporal structures of normative interface sounds can significantly improve auditory interface efficacy. First, participants rated tones with percussive amplitude envelopes as significantly less annoying than tones with flat amplitude envelopes. Crucially, this annoyance reduction did not come with a detection cost as percussive tones were detected more often than flat tones-particularly, at relatively low listening levels. Second, it was found that reductions in the duration of a tone's harmonics significantly lowered its annoyance without a commensurate reduction in detection. Together, these findings help inform our theoretical understanding of detection and annoyance of sound. In addition, they offer promising original design considerations for auditory interfaces.
听觉接口，如听觉警报，是人机交互的有用工具。不幸的是，较差的可检测性和烦扰性抑制了许多接口声音的效果。在这里，通过两种方式展示了如何超越传统规范接口声音的简单时间结构，可以显著提高听觉接口的效果。首先，参与者对具有打击乐幅度包络的音调的评价明显低于具有平坦幅度包络的音调，这是不令人讨厌的。至关重要的是，这种烦扰的减少并没有带来检测成本的增加，因为打击乐的音调比平坦的音调被检测到的频率更高，尤其是在相对较低的听力水平下。其次，人们发现，降低音调谐波的持续时间会显著降低其烦扰程度，而不会相应降低检测难度。总之，这些发现有助于我们从理论上理解声音的检测和烦扰。此外，它们为听觉接口的原始设计提供了有希望的考虑因素。
