Reading Room Acoustics in Libraries & Archives

Acoustic performance in a reading room directly impacts the functionality and occupant experience of libraries & archives buildings. The RT60 target of ≤0.5s 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 NR 25 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 ultra-low background noise levels (NR 25) in reading rooms while managing HVAC system noise, particularly from air handling units and terminal devices that typically produce NR 30–35 without acoustic attenuation.
