“20 Hz” is a creepy short horror film directed and written by Chris Keller that is centered around sounds that we as humans cannot hear. It follows a young lady, played by Alix Wilton Regan, who hears an eerie noise on her headphones while working on a song. She decides to investigate the sound and unfortunately finds what she was looking for.
Human hearing is capable of detecting sound waves between 20 and 20.000 Hz… merely a small fraction of the frequency spectrum. Most sounds around us go unnoticed.
