How the Hidden Sounds of Horror Movie Soundtracks Freak You Out (2016)

Horror movie soundtracks utilize various audio techniques to evoke fear and anxiety in viewers. Composers manipulate familiar sounds in unconventional ways, creating a sense of dread even before any visual threat appears. Techniques include using distorted instruments, distressing animal calls, and nonlinear sounds, which trigger instinctual fear responses. For instance, Harry Manfredini's iconic "ki ki ki ma ma ma" sound in "Friday the 13th" signals the presence of the killer Jason Voorhees, enhancing the viewer's tension. Additionally, infrasound—low-frequency sounds below human hearing—can create physical discomfort and unease, as seen in films like "Irreversible" and "Paranormal Activity." These sounds, often imperceptible, can lead to heightened anxiety due to their abstract nature, prompting the imagination to fill in the gaps. The evolution of horror soundtracks has shifted from orchestral scores to more atmospheric compositions, making the experience more immersive. This manipulation of sound transforms viewers from passive spectators into active participants, making them feel as if they are part of the unfolding horror.
