Godzilla Minus Zero is incredibly loud. Who decides on the cinema volume? And is it safe?
The new film, out in IMAX, has viewers shaking in their seats from the volume. Why are some cinema screenings so loud?
Godzilla Minus Zero's blockbuster soundscapes are leaving audiences feeling the force of the massive creature on the big screen. One IMAX viewer reported receiving a 90 decibel (dB) warning on their smartwatch, describing the film as the loudest they've ever watched. The question arises: why do some cinema screenings have such loud soundtracks, and is it safe?
The loudness of a film stems from its dynamic range, which is the difference between the quietest and loudest parts of the soundtrack. This range is much wider in cinemas than on personal audio devices. Additionally, the film's sound design plays a crucial role in creating a sense of scale. Godzilla's low-frequency rumblings and high-frequency details are reproduced by cinema subwoofers and detailed speakers, allowing viewers to perceive the monster's immense size and power.
The original Godzilla's 1954 roar was created by dragging a resin-coated glove across double bass strings, while composer Akira Ifukube developed a unique orchestral language for the creature. The IMAX version of Godzilla Minus Zero enhances the theatrical experience with advanced sound technologies, including 12-channel sound systems and enhanced presentation.
While filmmakers and studios meticulously mix audio to industry standards, cinemas are not required to maintain the exact volume and typically adjust it based on audience comfort, theatre acoustics, and business considerations. This means that despite the meticulous mixing process, cinema volume levels may vary from one screening to another.
Regarding safety concerns, hearing damage depends on both sound intensity and exposure time. A brief, loud sound is not equivalent to prolonged exposure at the same level. Hearing damage typically starts at a sustained level of 85 dBA, and no cinema soundtrack would consistently be at this level. Immediate permanent damage from a single sound is also highly unlikely, as it occurs at levels above 140dB.
Cinema staff manage volume levels to ensure compliance with legal thresholds, making sustained exposure to dangerously loud levels highly improbable.
