Why Projection Room Acoustics Matter in Cinemas & Screening Rooms
Acoustic performance in a projection room directly impacts the functionality and occupant experience of cinemas & screening rooms buildings. The RT60 target of Isolated is set to ensure that the space meets its intended purpose, whether that involves speech intelligibility, noise control, or sound isolation from adjacent areas.
The key metric of STC 55+ addresses the primary acoustic concern for this room type. Achieving this target typically requires a combination of absorptive surface treatments, appropriate construction mass, and careful attention to flanking paths and HVAC noise contributions.
Achieving NC 25 background noise and STC 65+ between adjacent auditoriums to prevent cross-talk during simultaneous screenings at reference level (85 dBC), particularly at low frequencies where bass extension can exceed 115 dB SPL.
