This study investigates the variability in sound levels experienced by moviegoers in commercial cinemas and its impact on the viewing experience. We measured playback levels in over forty cinemas, including both premium large-format auditoriums and standard theaters, and compared these levels with sound processor fader settings. Objective SPL readings were taken at various locations during reference pink noise playback. We also surveyed on-site operators and collected subjective feedback from audiences on their perceived loudness levels. Results revealed significant variability in both fader settings and actual playback levels, with many cinemas set below reference levels. Subjective feedback indicated a strong correlation between playback level and perceived loudness, with many respondents finding soundtracks "Too Loud" or "Slightly Too Loud," though dialog levels were generally rated as "About Right." The study highlights inconsistencies between existing sound level standards and audience satisfaction, suggesting a need for revised guidelines that balance objective measurements with audience preferences to enhance cinema sound quality.
