The Indepentent has published an interesting article talking about the psychoacoustics of non-linear horror sounds and music creations. Let’s read:
It is probably the most scary scene in cinematic history. The shower curtain is drawn back and actress Janet Leigh lets out a spine-chilling scream that warps into a frenzied cacophony of staccato music as she confronts an unseen, dagger-wielding madman.
When Alfred Hitchcock put the soundtrack to his 1960 masterpiece Psycho he was almost certainly unaware that the discordant musical notes he was adding to the disturbing shower scene were in fact based on the sort of non-harmonic sounds used in the distress calls of wild animals.
Scientists have found that many of the emotionally-evocative moments in some of the most popular films are enhanced with a sound score that exploits the human brain’s natural aversion to the “non-linear” sounds widely used in the animal kingdom to express fear and distress.
