Why Cinema Lobby Acoustics Matter in Cinemas & Screening Rooms
Acoustic performance in a cinema lobby directly impacts the functionality and occupant experience of cinemas & screening rooms buildings. The RT60 target of ≤1.0s 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 LAeq ≤55 dB 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.
