Loudspeaker Requirements in Object-Based Cinema

Object-based cinema formats present acoustical design challenges in the loudspeakers used in theaters, which require analytical study. This paper presents an in-depth analysis of the acoustic delivery requirements in a typical theater utilizing these formats. Further, the paper proposes a metric for loudspeaker placement and selection to be used in theater design. This becomes particularly useful for surround loudspeaker specifications knowing that object-based theaters utilize venue-specific rendering engines. The metric provides a means to both improve performance and reduce system cost compared to current methods.
