The presence (black) and absence (white) of specific acoustic attributes measured from film soundtracks as a function of film type (adventure, horror, sad, war). (a) Noise diegetic, p = 0.019; (b) noise musical, p = 0.003; (c) noise sound effects, p = 0.003; (d) abrupt amplitude fluctuation, p < 0.001; (e) abrupt frequency change shift down, p < 0.001; (f) abrupt frequency change shift up, p = 0.002; (g) sidebands musical, p = 0.002; (h) sidebands non-musical, p = 0.002; (i) noisy screams female, p = 0.002; (j) noisy screams male, p = 0.003. p-values are from a χ²-test, asterisks highlight those individual categories that are larger or smaller than expected by chance.
