Sound is as important as visuals in a film and plays a major role in creating emotional impact and completing the viewing experience. While audiences often focus more on cinematography, poor sound quality can be equally distracting. Since we naturally experience the world through multiple senses, films primarily combine sight and hearing to create a complete experience. Sound can also communicate things that are not visible, such as distant trains, thunder, fans, or barking dogs, allowing the audience to imagine unseen elements. It reinforces the realism of visuals and carries much of their emotional impact. While visuals can sometimes work without sound, the absence of expected sound is immediately noticeable. Thus, sound and visuals work together, with sound often being an unnoticed but essential part of the cinematic experience.
