Abstract

Many primates produce copulation calls, but we have surprisingly little data on what human sex sounds like. I present 34 h of audio recordings from 2239 authentic sexual episodes shared online. These include partnered sex or masturbation, but each recording has only one main vocalizer (1950 female, 289 male). Both acoustic features and arousal ratings from an online perceptual experiment with 109 listeners recruited on Prolific follow an inverted-U curve, revealing the likely time of orgasm. Sexual vocalizations become longer, louder, more high-pitched, voiced, and unpredictable at orgasm in both men and women. Men are not less vocal overall in this sample, but women start moaning at an earlier stage; speech or even minimally verbalized exclamations are uncommon. While excessive vocalizing sounds inauthentic to listeners, vocal bursts at peak arousal are ubiquitous and less verbalized than in the build-up phase, suggesting limited volitional control. Human sexual vocalizations likely include both consciously controlled and spontaneous moans of pleasure, which are perhaps best understood as sounds of liking rather than signals specific to copulation.

为什么人们在床上会发出声音?
许多灵长类动物都会发出交配的叫声,但关于人类性爱声音的数据却少得令人吃惊。我介绍了 34 小时的录音,这些录音来自网上共享的 2239 个真实的性爱场景。其中包括伴侣性行为或手淫,但每段录音只有一个主要发声者(1950 个女性,289 个男性)。在 Prolific 网站上招募的 109 名听众进行了在线感知实验,实验结果显示,声音特征和唤醒评分均呈倒 U 型曲线,揭示了性高潮的可能时间。在性高潮时,男性和女性的性发声都会变得更长、更响亮、音调更高、声音更大且更难以预测。在这一样本中,男性的发声总体上并没有减少,但女性开始呻吟的时间更早;说话或甚至微弱的口头感叹都不常见。虽然过度发声对听众来说听起来不真实,但唤醒高峰期的爆发性发声无处不在,而且与酝酿阶段相比口头发声较少,这表明意志控制能力有限。人类的性发声可能包括有意识控制的愉悦呻吟和自发的愉悦呻吟,也许最好将其理解为交配的声音而不是特定的信号。

期刊介绍: Evolution and Human Behavior is an interdisciplinary journal, presenting research reports and theory in which evolutionary perspectives are brought to bear on the study of human behavior. It is primarily a scientific journal, but submissions from scholars in the humanities are also encouraged. Papers reporting on theoretical and empirical work on other species will be welcome if their relevance to the human animal is apparent.
