Over the past few years, the subject of movies getting louder has generated increasing concern within the film production community. In addition, it has become commonplace for moviegoers to claim that movies are too loud. Many theatres now project films at an audio fader setting below the calibration setting that would match that in the dubbing theatre, presumably because of audience complaints. The following material discusses some of the issues that can be described as sound-track “loudness.” What is a measure of “loudness” for a movie? Why do theatres turn the sound down? Have new sound formats (Dolby SR and more recently the digital formats, Dolby SR•D, Sony SDDS, and DTS) exacerbated the perceived loudness problem? This paper describes an investigation aimed at defining perceived long-term sound-track loudness with a meter reading, and some data are presented.
