Existing research links subjective judgments of perceived laughter intensity with features such as duration, amplitude, fundamental frequency, and voicing. We examine these associations in a new database of social laughs produced in situations inducing amusement, embarrassment, and schadenfreude. We also test the extent to which listeners’ judgments of laughter intensity vary as a function of the social situation in which laughs were produced.
