Operating Theatre Acoustics in Hospitals & Healthcare

Acoustic performance in a operating theatre directly impacts the functionality and occupant experience of hospitals & healthcare buildings. The RT60 target of ≤0.6s 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 35–40 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.

Balancing patient privacy and sleep quality with the need for clear staff communication in high-noise clinical environments, while meeting infection-control requirements that restrict material choices.
