人们对笑声的声学特征知之甚少。在这里，声学结果报告了1024自然产生的笑声，从97个年轻人，因为他们观看有趣的视频剪辑记录。分析集中在时间特征上。生产模式，源和过滤器相关的影响，和索引线索笑性别和个人身份。虽然许多研究人员以前强调了笑声中的刻板印象，但现在发现它的声学效果是可变的和复杂的。在各种各样的调查结果报告，生产模式的明显多样性，显着的变化，在基本频率特性，并一致缺乏清晰度的影响，在喉上过滤是特别感兴趣的。此外，共振峰相关的过滤效果被认为是不成比例的重要性，作为声学相关的笑的性别和个人身份。这些结果是根据有关笑声声学的现有数据以及之前关于这种物种典型的声音信号提出的许多假设和猜想来检验的。(C)2001年，美国声学学会。
Remarkably little is known about the acoustic features of laughter. Here, acoustic outcomes are reported for 1024 naturally produced laugh bouts recorded from 97 young adults as they watched funny video clips. Analyses focused on temporal features. production modes, source- and filter-related effects, and indexical cues to laugher sex and individual identity. Although a number of researchers have previously emphasized stereotypy in laughter, its acoustics were found now to be variable and complex. Among the variety of findings reported, evident diversity in production modes, remarkable variability in fundamental frequency characteristics, and consistent lack of articulation effects in supralaryngeal filtering are of particular interest. In addition, formant-related filtering effects were found to be disproportionately important as acoustic correlates of laugher sex and individual identity. These outcomes are examined in light of existing data concerning laugh acoustics, as well as a number of hypotheses and conjectures previously advanced about this species-typical vocal signal.
