Horror film soundtracks mimic animal distress calls. Film-makers' manipulations of sound tap into our primal fears, say researchers
Discordant sounds used to create tension in horror films are effective because they mimic calls made by animals in the wild at times of stress, researchers have found. The "non-linear" sounds, often created by pushing brass and wind instruments beyond their natural range by playing them too hard, exploit the human brain's natural aversion to sonics that signal fear or distress.
